Personal Jurisdiction Over Corporations in Federal Court: The \"At Home\" Test, Consent by Registration After Mallory, Stream of Commerce, and Relatedness

Two decisions decided fifteen years apart have made corporate personal jurisdiction a narrower and more technical field than the one most practitioners learned. Daimler AG v. Bauman killed the old "doing business" theory of general jurisdiction, and Mallory v. Norfolk Southern Railway Co. revived a 1917 consent-by-registration case that had been dormant for a century. The combined effect is that the winning argument in a corporate jurisdiction motion is frequently not about contacts at all — it is about where the entity is incorporated, where it is headquartered, and what the forum state's registration statute says in terms.

The corporate analysis differs from the individual one in structure, not just in degree. A natural person has a domicile, a body that can be served, and a finite set of intentional acts. A corporation is a legal fiction with a chartered home, an operational headquarters, subsidiaries, distributors, registered agents, and a nationwide sales footprint — any of which a plaintiff will characterize as "presence." The Supreme Court's project since 2011 has been to insist that most of those things are irrelevant to all-purpose jurisdiction and must instead be channeled through specific jurisdiction, where relatedness does real work.

This guide covers what decides these motions: the "at home" paradigm and its two anchors, the registration-statute question that Mallory reopened, purposeful availment and relatedness for entity defendants, the corporate-family theories that survive and the one Daimler destroyed, and the service-authority step under Rule 4 that is skipped more often than any other.

The two-track structure as applied to entities

Jurisdiction over a corporation comes from one of three sources, and they are not interchangeable.

The practical consequence of the narrowing is a reallocation of work. Before 2011, a plaintiff suing a national retailer or manufacturer in a state where it operated stores, warehouses, or a regional office could plead general jurisdiction and never confront relatedness. After Daimler, that route is closed everywhere except the two home states, so nearly every contested corporate motion is now a relatedness fight — which is why Bristol-Myers Squibb Co. v. Superior Court and Ford Motor Co. v. Montana Eighth Judicial Dist. Court are the two most-cited cases in current practice.

Note what is not on the list. Corporate "presence," the pre-International Shoe concept that a company doing business in a state was constructively there, is gone as an independent basis. So is the idea that a corporation's ownership of in-state property confers jurisdiction over unrelated claims: Shaffer v. Heitner subjected every assertion of state-court jurisdiction, including quasi in rem, to the International Shoe standard, so a corporate defendant's in-state assets are one contact among many rather than a freestanding hook.

The service-authority step: Rule 4(k) and Omni Capital

Before the due-process question there is a statutory one, and it is independently dispositive.

Omni Capital Int'l, Ltd. v. Rudolf Wolff & Co. holds that due-process sufficiency is not enough: "before a court may exercise personal jurisdiction over a defendant, there must be more than notice to the defendant.... There also must be a basis for the defendant's amenability to service of summons. Absent consent, this means there must be authorization for service of summons on the defendant." The plaintiffs there sued a British broker and its agent under the Commodity Exchange Act, which contained no nationwide-service provision, and Louisiana's long-arm did not reach them. The Court declined to fashion a federal common-law service rule to cover the gap.

Rule 4(k)(1) supplies the authorization:

• (k)(1)(A) — the borrowing rule. Service establishes jurisdiction over a defendant "who is subject to the jurisdiction of a court of general jurisdiction in the state where the district court is located." In the great majority of federal cases this means the forum state's long-arm statute governs the corporate defendant's amenability, and a federal court in that state has no greater reach than its state courts.
• (k)(1)(B) — the 100-mile bulge for parties joined under Rule 14 or Rule 19.
• (k)(1)(C) — service authorized by federal statute.
• (k)(2) — the federal long-arm: for a claim arising under federal law, against a defendant "not subject to jurisdiction in any state's courts of general jurisdiction," if the exercise is consistent with the Constitution. This provision was written in direct response to Omni Capital, and it is the one most often overlooked when the defendant is a foreign entity with diffuse United States contacts that add up nationally but are insufficient in any single state.

Federal nationwide-service statutes change the sovereign whose contacts matter. 18 U.S.C. § 1965 (RICO), 15 U.S.C. § 22 (Clayton Act), 15 U.S.C. § 78aa (Exchange Act), and 29 U.S.C. § 1132 (ERISA) each authorize service beyond the forum state. Where one applies, the constitutional test is a Fifth Amendment national-contacts inquiry rather than a Fourteenth Amendment forum-state one — a distinction that makes an antitrust or securities defendant reachable in a district where a common-law plaintiff could never sue it. Read the provision's text carefully: § 22 and § 1965 have venue and service clauses that courts have not read identically, and the circuits differ on whether § 1965(b)'s "ends of justice" clause requires a showing beyond nationwide service.

The state long-arm text matters even when the defendant is a large company. Some long-arm statutes reach as far as due process permits, collapsing the two questions into one. Others enumerate acts — transacting business, contracting to supply goods, causing tortious injury by an act inside or outside the state — and an enumerated statute can defeat jurisdiction the Constitution would tolerate. A brief that argues only minimum contacts forfeits the statutory ground.

General jurisdiction: from International Shoe to "at home"

International Shoe Co. v. Washington is the origin of both tracks, and it is worth recovering what it actually said about corporations, because the passage has been read two ways. Washington sought unemployment-compensation contributions from a Delaware corporation headquartered in St. Louis that employed eleven to thirteen commission salesmen in Washington. The Court sustained jurisdiction on the familiar formulation — a defendant must have "certain minimum contacts with it such that the maintenance of the suit does not offend traditional notions of fair play and substantial justice" — and then sketched a four-part taxonomy that has organized the field ever since: continuous and systematic activity giving rise to the claim; single or occasional acts giving rise to the claim; continuous and systematic activity not giving rise to the claim; and casual, isolated activity unrelated to the claim.

The third category is general jurisdiction, and International Shoe described it in a sentence that generated sixty years of confusion: there have been instances in which "continuous corporate operations within a state were thought so substantial and of such a nature as to justify suit against it on causes of action arising from dealings entirely distinct from those activities." Lower courts read "substantial, continuous and systematic" as a test — a sliding scale on which enough in-state business, of any kind, made a company suable for anything. That reading is the one Daimler rejected.

Helicopteros Nacionales de Colombia, S.A. v. Hall was the intervening data point and should have been the warning. Helicol, a Colombian carrier, had sent its chief executive to Miami to negotiate a contract, purchased roughly 80 percent of its helicopter fleet and substantial parts and training from a Fort Worth manufacturer, and received payments drawn on a Texas bank. The Court held Texas lacked general jurisdiction over a wrongful-death suit arising from a crash in Peru. Purchases, "even if occurring at regular intervals," do not warrant all-purpose jurisdiction, and the contract negotiation was a single trip. Helicopteros also gave the doctrine its vocabulary: the opinion's footnotes coined the modern terms for the two tracks.

Perkins: the surviving exceptional case

Perkins v. Benguet Consolidated Mining Co. is the only decision in which the Supreme Court has ever upheld general jurisdiction over a foreign corporation outside its formal home, and understanding why explains the modern test.

Benguet was a Philippine mining company whose Philippine operations were halted by the Japanese occupation. Its president moved to Ohio, maintained an office there, kept the company's files there, held directors' meetings there, carried two active bank accounts there, distributed salary checks drawn on Ohio accounts, supervised the rehabilitation of the Philippine properties from Ohio, and used an Ohio bank as transfer agent. The Court held Ohio could entertain claims unrelated to any Ohio activity, because the company's "continuous and systematic supervision of the necessarily limited wartime activities of the company" made Ohio the place where its business was in fact conducted.

Daimler reinterpreted Perkins into the current framework: Ohio was "the corporation's principal, if temporary, place of business," so the company was at home there. That reading converts Perkins from a high-water mark of the doing-business test into an ordinary application of the at-home test, which is exactly how it now functions. The reserved exceptional case — the possibility that a corporation's operations elsewhere might be "so substantial and of such a nature as to render the corporation at home in that State" — is a Perkins scenario: the entity's real center of gravity has relocated to the forum. It is not a large-operations scenario, as BNSF confirmed.

Goodyear, Daimler, and BNSF: the Court narrowing itself

Three decisions in six years cut general jurisdiction down, and each rejected a theory that the lower courts had treated as settled. Read together they are the clearest modern example of the Court dismantling a doctrine built on its own earlier language.

Goodyear Dunlop Tires Operations, S.A. v. Brown (2011). Two North Carolina boys died in a bus accident outside Paris, allegedly caused by a defective tire manufactured in Turkey by a Goodyear subsidiary. The plaintiffs sued the foreign subsidiaries in North Carolina, relying on the fact that tires made by those subsidiaries reached the state through the corporate family's distribution channels. A unanimous Court reversed. The opinion introduced the phrase that now controls: a forum may exercise all-purpose jurisdiction only where the corporation's affiliations with the State are "so 'continuous and systematic' as to render [it] essentially at home in the forum State." The Court also corrected a widespread misreading of the stream-of-commerce cases — World-Wide Volkswagen Corp. v. Woodson and its successors are specific-jurisdiction cases, and "[f]low of a manufacturer's products into the forum... may bolster an affiliation germane to specific jurisdiction," but does not support general jurisdiction.

Daimler AG v. Bauman (2014). Argentinian residents sued Daimler, a German company, in California over alleged collaboration between its Argentinian subsidiary and state security forces during the Dirty War. No party, no conduct, and no injury was Californian. The Ninth Circuit had upheld jurisdiction on an agency theory: Daimler's American distribution subsidiary, Mercedes-Benz USA, performed services in California important enough that Daimler would perform them itself if MBUSA did not, so MBUSA's substantial California contacts were imputed to the parent.

The Court reversed and did two distinct things.

1. It rejected the doing-business test. The plaintiffs' submission that general jurisdiction exists wherever a corporation "engages in a substantial, continuous, and systematic course of business" was, the Court said, "unacceptably grasping." International Shoe's reference to continuous operations "elsewhere" was not a general-jurisdiction formula. And the Court stressed the point that most often decides motions today: the inquiry "is not whether a foreign corporation's in-forum contacts can be said to be in some sense 'continuous and systematic,' it is whether that corporation's affiliations with the State are so continuous and systematic as to render it essentially at home in the forum State." The comparison is to the corporation's activities in their entirety, nationwide and worldwide, not to a threshold of in-state volume.
2. It rejected the agency theory. The Ninth Circuit's "important enough that the parent would perform them itself" standard "stacks the deck, for it will always yield a pro-jurisdiction answer." Because a parent will by definition find its distribution functions important, the test would subject multinationals to general jurisdiction in every state where they have a functioning distributor. Footnote 20 left open whether agency principles might ever bear on specific jurisdiction, but as to general jurisdiction the theory is dead.

Daimler also fixed the paradigm. The "paradigm all-purpose forums" for a corporation are its place of incorporation and its principal place of business — the two places borrowed, by the Court's own comparison, from the diversity-citizenship analysis in Hertz Corp. v. Friend and its "nerve center" test. Footnote 19 reserved the possibility of an exceptional case, citing Perkins, in which operations elsewhere could render a corporation at home. In more than a decade no Supreme Court case has found one.

BNSF Railway Co. v. Tyrrell (2017). This is the case that forecloses the volume argument, and it is the one to cite when a plaintiff tells you the defendant's in-state footprint is simply too big to ignore. BNSF is incorporated in Delaware with its principal place of business in Texas. In Montana it had about 2,000 employees, roughly 2,061 miles of railroad track, six percent of its total track mileage, an automotive parts distribution center, and derived some ten percent of its revenue. Montana's courts held that enough. The Supreme Court reversed 8-1: "the general jurisdiction inquiry does not focus solely on the magnitude of the defendant's in-state contacts," and in-state business "does not suffice to permit the assertion of general jurisdiction over claims... that are unrelated to any activity occurring in Montana."

BNSF also disposed of a statutory argument worth knowing because analogues recur. The plaintiffs relied on FELA's venue provision, 45 U.S.C. § 56, which allows suit in a district where the carrier "shall be doing business at the time of commencing such action," contending that Congress had thereby authorized state-court personal jurisdiction over railroads wherever they operate. The Court held the provision addresses venue in federal court, not personal jurisdiction, and that the second sentence's concurrent-jurisdiction clause is a subject-matter provision. A statute that speaks to venue or to subject-matter jurisdiction does not supply personal jurisdiction; that argument fails the same way whenever it is made.

The arc is worth stating plainly for a brief: Perkins (1952) upheld general jurisdiction where the forum had become the company's operational home; Helicopteros (1984) refused it for regular purchases and a negotiation trip; Goodyear (2011) supplied the "at home" formulation and pulled the stream-of-commerce cases out of general jurisdiction; Daimler (2014) discarded the doing-business test and the agency theory; BNSF (2017) confirmed that magnitude alone is irrelevant. The doctrine the casebooks taught for two generations was retired by the Court that wrote it.

Consent by registration after Mallory

Everything above concerns the contacts track. The consent track is independent of it, and in 2023 it became the most important open question in the field.

The 1917 case. Pennsylvania Fire Ins. Co. of Philadelphia v. Gold Issue Mining & Milling Co. upheld a Missouri judgment against an Arizona-chartered insurer on a policy covering Colorado property, sued upon in Missouri by a Missouri-licensed plaintiff. Missouri required a foreign insurer, as a condition of doing business in the state, to file a power of attorney consenting that service on the state superintendent would be as valid as personal service. Justice Holmes, for a unanimous Court, held that the state was entitled to take the insurer at its word: the company had "executed a power of attorney that made service on the superintendent the equivalent of personal service," and the resulting jurisdiction was valid even for a claim with no Missouri connection.

The long dormancy. After International Shoe reoriented the field around contacts, Pennsylvania Fire went essentially unused. The prevailing lower-court view — near-unanimous after Daimler — was that registration and appointment of an agent were the routine price of doing business, not consent to all-purpose jurisdiction, and that reading a generic registration statute as consent would resurrect the doing-business test Daimler had just buried. Many state supreme courts said so explicitly between 2014 and 2022.

Mallory v. Norfolk Southern Railway Co. (2023). Mallory, a Virginia resident, sued Norfolk Southern — incorporated and headquartered in Virginia — in Pennsylvania state court under FELA for occupational cancer allegedly contracted from exposures in Ohio and Virginia. Under Daimler and BNSF there was plainly no general jurisdiction, and no specific jurisdiction. The plaintiff relied entirely on Pennsylvania's registration scheme, which is unusual in that its statutory text expressly provides that qualification as a foreign corporation permits Pennsylvania courts to exercise general personal jurisdiction over the registrant. Norfolk Southern had registered and had an extensive Pennsylvania operation.

The Pennsylvania Supreme Court held the statute unconstitutional. The Supreme Court reversed, and the precise contours of what it held matter enormously:

• The holding is narrow and precedent-bound. A five-Justice majority on this point held that Pennsylvania Fire controls and has never been overruled, so a state statute that requires an out-of-state corporation to consent to general jurisdiction as a condition of doing business in the state does not violate the Due Process Clause. Justice Gorsuch's opinion emphasized that International Shoe "did not purport to overrule" the consent line; the contacts test supplements rather than replaces it.
• The Court fractured. There was no single majority opinion for the whole judgment. Parts of Justice Gorsuch's opinion commanded only a plurality; Justice Alito supplied the fifth vote by concurring in part and in the judgment on the due-process question alone.
• The dormant Commerce Clause is left open. Justice Alito's concurrence is the most consequential document in the case for planning purposes. He agreed that due process does not forbid Pennsylvania's scheme, but wrote separately to flag a "seriously" different question: whether a statute conditioning the privilege of doing interstate business on submission to all-purpose jurisdiction unduly burdens interstate commerce. He identified the difficulty of finding a legitimate local interest in hearing a Virginia plaintiff's claim against a Virginia defendant about Ohio and Virginia conduct. That issue was not decided and was left for remand.
• No merits ruling on notice or fairness beyond due process. The Court did not address whether Pennsylvania's statute survives any other constitutional objection, and the majority expressly noted the limited question presented.

What practitioners should actually do. The operative instruction from Mallory is textual, not conceptual: read the forum state's registration statute. Most states' registration and agent-appointment statutes do not contain Pennsylvania's explicit consent-to-general-jurisdiction language. They require a foreign corporation to qualify and to designate an agent for service, and nothing more. For those statutes the pre-Mallory analysis is largely unchanged, because Mallory rests on Pennsylvania having said in terms what other legislatures did not say — and Daimler's rejection of the doing-business test still forbids inferring all-purpose consent from the bare fact of qualification. A handful of states have amended or are considering amending their statutes to add express consent language, and a few courts have found consent in older statutes with unusually broad text, so the survey has to be done state by state and version by version, with attention to which version was in force when the defendant registered.

Three further practice points follow. First, a registration-based consent argument is not a contacts argument, so a defendant's affidavit about the modest scale of its in-state operations does not answer it; the answer is the statutory text. Second, where a plaintiff invokes consent under a generic statute, brief Daimler structurally — treating registration as consent would restore the very regime Daimler rejected, and would do so without the legislature having said so. Third, where the statute does contain express consent language, the live defense is now the dormant Commerce Clause theory Justice Alito sketched, plus any state-law argument that the statute does not apply to the claim or the registrant; preserve both, because the due-process argument is foreclosed.

Specific jurisdiction over an entity

With general jurisdiction confined to two states, specific jurisdiction carries nearly the entire load. The test has two steps and a threshold: the defendant must have purposefully directed conduct at the forum; the claim must arise out of or relate to that conduct; and the exercise must be reasonable.

Purposeful availment. Hanson v. Denckla supplies the requirement — jurisdiction demands "some act by which the defendant purposefully avails itself of the privilege of conducting activities within the forum State, thus invoking the benefits and protections of its laws" — and the corollary that the unilateral activity of a third party is not the defendant's contact. McGee v. International Life Ins. Co. marks the far edge for a corporate defendant: a Texas insurer that assumed a single policy, mailed a reinsurance certificate to a California insured, and accepted premiums mailed from California was subject to California jurisdiction on a beneficiary's suit on that policy. One deliberate transaction with a forum resident, on a claim about that transaction, can be enough.

Burger King Corp. v. Rudzewicz is the contract-contacts framework and is the case a corporate plaintiff or defendant will brief most heavily. Though the defendant was an individual franchisee, the opinion's analytical structure is applied indiscriminately to entities, and its four propositions are the operative ones:

1. A contract with an out-of-state party is not automatically a sufficient contact; the court examines prior negotiations, contemplated future consequences, the terms of the contract, and the parties' actual course of dealing.
2. A choice-of-law clause is not dispositive but "reinforce[s] [the defendant's] deliberate affiliation with the forum State."
3. Physical presence is unnecessary — "it is an inescapable fact of modern commercial life that a substantial amount of business is transacted solely by mail and wire communications across state lines."
4. The purposeful-availment requirement ensures that a defendant is not haled into a forum "solely as a result of random, fortuitous, or attenuated contacts" or "of the unilateral activity of another party or a third person."

Burger King also states the burden allocation on reasonableness that decides the second step: once purposeful direction is shown, the defendant "must present a compelling case that the presence of some other considerations would render jurisdiction unreasonable."

Reasonableness. The factors come from World-Wide Volkswagen Corp. v. Woodson and Asahi Metal Industry Co. v. Superior Court: the burden on the defendant, the forum state's interest, the plaintiff's interest in convenient and effective relief, the interstate judicial system's interest in efficiency, and the shared interest of the states in fundamental substantive social policies. For a domestic corporate defendant this step almost never wins — cost and distance are features of every out-of-state suit. Asahi is the rare case decided on it, and its posture explains why: the underlying personal-injury claim had settled, and what remained was an indemnity dispute between a Japanese valve manufacturer and a Taiwanese tube manufacturer with which California had no real concern. The Court noted that "the unique burdens placed upon one who must defend oneself in a foreign legal system should have significant weight." Reasonableness is a foreign-defendant argument.

Stream of commerce: Asahi and McIntyre

Product-liability jurisdiction over a component maker or foreign manufacturer turns on a question the Supreme Court has twice failed to answer.

World-Wide Volkswagen held that Oklahoma could not reach a New York retailer and a regional tri-state distributor because an Audi they sold in New York was driven to Oklahoma and burned there. The foreseeability that matters "is not the mere likelihood that a product will find its way into the forum State," but "that the defendant's conduct and connection with the forum State are such that he should reasonably anticipate being haled into court there." But the opinion also contained the dictum that produced three decades of litigation: jurisdiction is proper over a corporation that "delivers its products into the stream of commerce with the expectation that they will be purchased by consumers in the forum State."

Asahi split on what that dictum means, and the split survives.

Because the Court unanimously found jurisdiction unreasonable at step two, the split was unnecessary to the result and unresolved.

J. McIntyre Machinery, Ltd. v. Nicastro (2011) was the Court's chance to fix it and did not. A New Jersey worker was injured by a metal shearing machine made by an English manufacturer that sold through an independent Ohio distributor; at most four of its machines reached New Jersey, and the manufacturer had attended trade shows in the United States but never in New Jersey. The New Jersey Supreme Court had adopted an expansive stream-of-commerce theory keyed to the national distribution system. The Supreme Court reversed, but only a four-Justice plurality joined Justice Kennedy's reasoning, which adopted something close to O'Connor's position and emphasized that "the defendant's transmission of goods permits the exercise of jurisdiction only where the defendant can be said to have targeted the forum." Justice Breyer, joined by Justice Alito, concurred in the judgment on the narrower ground that the Court's existing precedents — a single isolated sale, no regular flow — resolved the case, and expressly declined to announce a rule for modern commerce, including internet sales. Three Justices dissented.

The consequence for practice is that there is no majority rule, and the governing standard is circuit and state law. Some circuits apply stream-of-commerce-plus in terms; some continue to apply a foreseeability-plus-volume analysis in substance; several have simply held that McIntyre's lack of a majority left their prior precedent intact. A component-supplier motion should therefore be briefed on the forum's own law first, with Goodyear's reminder that product flow can "bolster an affiliation germane to specific jurisdiction" and McIntyre's targeting language deployed as the constitutional ceiling. Note also the argument Goodyear foreclosed: a plaintiff cannot use product flow to establish general jurisdiction, so the stream-of-commerce theory must be paired with a related claim.

A recurring modern variant is the internet retailer or platform. Neither Asahi nor McIntyre addressed it — Justice Breyer pointedly reserved it — and the lower courts have converged loosely on an interactivity-and-targeting analysis: a passive site accessible in the forum is not purposeful availment, while a site that accepts forum orders, ships into the forum, localizes content or currency, or runs forum-directed advertising generally is. The relatedness requirement then does the limiting work described next.

Relatedness: Bristol-Myers Squibb and Ford

Once general jurisdiction was confined to two states, relatedness became the battlefield. Two decisions four years apart set its outer bounds, and they point in opposite directions — which is why both appear in every brief.

Bristol-Myers Squibb Co. v. Superior Court (2017) is the limit. Six hundred and seventy-eight plaintiffs, only 86 of them California residents, sued BMS in California state court over the blood thinner Plavix. BMS is incorporated in Delaware, headquartered in New York, and conducts substantial research in New Jersey. In California it had five research and laboratory facilities, some 250 sales representatives, a state-government advocacy office, and had sold nearly 187 million Plavix pills in the state for more than $900 million. The nonresident plaintiffs had not been prescribed, purchased, or ingested Plavix in California and were not injured there.

The California Supreme Court had upheld jurisdiction on a "sliding scale" theory: because BMS's California contacts were extensive, a looser connection between those contacts and the nonresidents' claims would do. The Supreme Court reversed 8-1 and rejected the sliding scale outright. The operative sentences:

• "In order for a state court to exercise specific jurisdiction, the suit must aris[e] out of or relat[e] to the defendant's contacts with the forum." What is needed is "an affiliation between the forum and the underlying controversy, principally, [an] activity or an occurrence that takes place in the forum State."
• "A corporation's 'continuous activity of some sorts within a state is not enough to support the demand that the corporation be amenable to suits unrelated to that activity.'"
• The mere fact that other plaintiffs were prescribed and injured in California "does not allow the State to assert specific jurisdiction over the nonresidents' claims," because specific jurisdiction is assessed claim by claim and defendant by defendant.
• The presence of a California distributor did not help, because the relevant question is the defendant's conduct connecting it to the forum, and a plaintiff cannot rely on a "relationship among the defendant, the forum, and the litigation" built out of third-party conduct.

Bristol-Myers Squibb is the reason mass-tort and pharmaceutical litigation consolidated in defendants' home states and in federal MDLs. It also disposes of the most common plaintiff-side argument in current motion practice: that a national company's large in-state sales volume must count for something. It counts only for claims connected to the forum.

Ford Motor Co. v. Montana Eighth Judicial Dist. Court (2021) is the counterweight, and it is narrower than plaintiffs often claim. Two suits: a Montana resident killed in a Montana rollover of a Ford Explorer originally sold in Washington, and a Minnesota resident injured in a Minnesota crash of a Crown Victoria originally sold in North Dakota. Each car had been resold into the forum state by third parties. Ford argued that because it had not sold those vehicles in the forum, the claims did not arise out of its forum contacts.

The Court unanimously rejected that causal framing and held that the standard phrase is disjunctive: "The first half of that standard asks about causation; but the back half, after the 'or,' contemplates that some relationships will support jurisdiction without a causal showing." Ford had systematically advertised, marketed, sold, and serviced the same vehicle models in Montana and Minnesota, cultivated a market for repeat purchases and resales, and supplied replacement parts through in-state dealers. That conduct bore a strong enough relationship to claims about those models' safety in those states.

Two limits in Ford are frequently omitted from plaintiff briefs and should be pressed:

1. "Relate to" is not a but-for test. The Court said the phrase "does not mean anything goes" and "incorporates real limits." A causal chain running from the defendant's forum activity to the plaintiff's injury is neither necessary nor sufficient.
2. The link was model-specific and market-specific. Ford's contacts concerned the very product lines at issue, and the plaintiffs were forum residents injured in the forum. The Court distinguished Bristol-Myers Squibb on precisely those grounds — there the nonresident plaintiffs' claims had "no connection" to the forum at all.

The reconciliation that governs today: Bristol-Myers Squibb holds that unconnected in-state sales cannot support a nonresident plaintiff's unconnected claim, no matter the volume; Ford holds that in-state cultivation of the market for the specific product that injured a forum resident in the forum will support jurisdiction even without a sale-of-this-unit causal link. The question in every motion is which of those two patterns the case resembles.

Publishers, media, and the effects test

Publishing entities generate their own line, and it is the one corner where an entity's in-forum circulation is itself the contact.

Keeton v. Hustler Magazine, Inc. allowed a New Hampshire libel action by a plaintiff who was not a New Hampshire resident and had almost no connection to the state, because the magazine's regular monthly circulation of 10,000 to 15,000 copies there was a deliberate contact and the claim arose from that circulation. The Court rejected the argument that the plaintiff's lack of forum ties defeated jurisdiction — the plaintiff's contacts are relevant to reasonableness, not to minimum contacts — and rejected the notion that a publisher's exposure should be limited to where it does most of its business. Keeton remains the strongest authority for jurisdiction over a media defendant that sells or distributes into the forum.

Calder v. Jones, decided the same day, supplied the effects test for the individuals who produce the content. The Court sustained California jurisdiction over a Florida reporter and editor whose National Enquirer article concerned the California activities of a California entertainer, drew on California sources, and injured her reputation in the state where the magazine's circulation was largest. Their "intentional, and allegedly tortious, actions were expressly aimed at California."

Walden v. Fiore is the limit and the first case to cite in any modern effects-test motion. A Georgia DEA agent seized cash from Nevada residents in an Atlanta airport and allegedly drafted a false affidavit knowing they lived in Nevada. The Court reversed unanimously: "the proper question is not where the plaintiff experienced a particular injury or effect but whether the defendant's conduct connects him to the forum in a meaningful way," and a defendant's relationship with a plaintiff who happens to reside in the forum is "an insufficient basis for jurisdiction." Walden also recharacterized Calder: the reputational tort there was connected to California because that is where the audience and the reputation were, not merely because that is where the plaintiff lived.

For corporate defendants the practical synthesis is straightforward. Distribution, subscriptions, advertising sales, or targeted content in the forum are the entity's own contacts and support claims arising from them (Keeton). Knowledge that a corporate plaintiff is headquartered in the forum, or that the harm will be felt there, is not enough (Walden). A defamation or trade-libel claim against an online publisher therefore turns on forum-directed audience, advertising, and subject matter, not on where the plaintiff's balance sheet suffered.

Corporate families: parent, subsidiary, alter ego, agency

Plaintiffs routinely try to reach a foreign or out-of-state parent through a forum subsidiary. After Daimler, only some of those theories remain.

Separate corporate existence is the baseline. A subsidiary's contacts are not the parent's, and the ordinary incidents of ownership — holding stock, electing directors, receiving dividends, approving budgets, consolidated financial reporting, shared trademarks, a common insurance program — do not make the parent present in the forum. Nor does a parent's general oversight of a subsidiary's business.

Alter ego survives. Where the corporate form is disregarded on traditional veil-piercing grounds, the subsidiary's contacts are attributed to the parent because the two are treated as one entity. The showing is the familiar substantive one and it is demanding: undercapitalization, commingled funds, disregard of corporate formalities, common officers and employees performing the same functions without distinction, the parent's payment of the subsidiary's obligations, absence of arm's-length dealing, and use of the form to work a fraud or injustice. Circuits differ on whether the source of that standard is forum state law or a federal common-law rule, and on whether a fraud showing is required in the jurisdictional context as opposed to the liability context; brief the forum's formulation.

Agency for general jurisdiction is dead. Daimler rejected the Ninth Circuit's test — imputation whenever the subsidiary performs services "sufficiently important to the foreign corporation that it would perform them itself if it had no representative" — because it "stacks the deck" and "will always yield a pro-jurisdiction answer." Any brief still relying on pre-2014 "agency" or "representative services" cases for general jurisdiction over a parent is relying on overruled authority.

Agency for specific jurisdiction is narrower but not foreclosed. Daimler reserved the question in a footnote, and traditional agency principles still operate where the subsidiary or distributor acted as the parent's actual agent with respect to the transaction at issue — for example, negotiating or performing the contract that gave rise to the claim, or acting under the parent's control in the forum conduct that caused the injury. The distinction to hold onto is that specific-jurisdiction agency is transaction-specific and requires control over the relevant conduct, not a general assessment of corporate importance. Plaintiffs also litigate a related "conspiracy jurisdiction" theory, which most courts require to be supported by forum acts by a co-conspirator taken in furtherance of the conspiracy plus the defendant's knowledge, and which several courts reject outright.

Successors and mergers. A successor that assumes a predecessor's liabilities generally inherits the predecessor's jurisdictional contacts as to those liabilities; courts split on whether that follows automatically from successor liability or requires an independent contacts showing. A merger that formally extinguishes the predecessor is the cleanest case for imputation.

Because all of these theories are fact-intensive, a plaintiff who pleads them conclusorily will be met with a motion and, at most, narrowly bounded discovery. Plead specific facts about who did what — shared employees performing the same role, who signed the contract, who controlled the forum conduct — or expect to lose the discovery request.

Consent, waiver, and forum-selection clauses

Personal jurisdiction protects a liberty interest, and a liberty interest can be surrendered. Insurance Corp. of Ireland v. Compagnie des Bauxites de Guinee is the foundational statement and matters for two reasons.

First, the principle: "the personal jurisdiction requirement recognizes and protects an individual liberty interest," and therefore, unlike subject-matter jurisdiction — which "functions as a restriction on federal power" that no party can enlarge — it "can, like other such rights, be waived." That asymmetry is why a corporate defendant must raise the defense on time and why no amount of consent can create subject-matter jurisdiction.

Second, the sanction. The defendants were foreign insurers who resisted discovery directed at their forum contacts through two years of orders, an order to compel, and a warning. The district court imposed a Rule 37(b)(2) sanction establishing the jurisdictional facts — treating the contacts as admitted — and the Supreme Court affirmed. A corporate defendant that stonewalls jurisdictional discovery can lose the jurisdictional question by default, and the presumption the Court approved is a real one: the sanction was upheld as a permissible inference that the withheld evidence would have supported jurisdiction. This is the single most important reason to respond to jurisdictional discovery even while contesting it.

Waiver by procedure. Under Rule 12(h)(1), the defense is waived if omitted from a Rule 12 motion made before the responsive pleading, or if not raised in the answer or in an amendment allowed as of course. Corporate defendants lose the defense most often by filing a motion to dismiss on other grounds first, or by litigating the merits for a year before pressing an answered objection. Affirmative counterclaims, broad merits discovery, and long delay have all been held to forfeit a properly pleaded defense.

Removal does not waive it. A corporate defendant that removes under 28 U.S.C. § 1441 may still move under Rule 12(b)(2); removal is not an appearance consenting to jurisdiction. Nor does a Rule 12(b)(2) motion waive venue or forum non conveniens, provided they are raised together.

Agent-appointment clauses. National Equipment Rental, Ltd. v. Szukhent enforced a lease provision appointing a named New York agent for service, even though the appointed agent was unknown to the defendants and connected to the plaintiff, because the appointment was voluntarily given and the papers were promptly forwarded. Contractual appointment of an agent remains fully effective and is a common feature of commercial paper.

Forum-selection clauses. M/S Bremen v. Zapata Off-Shore Co. holds such clauses "prima facie valid" and enforceable unless the resisting party shows enforcement would be unreasonable — fraud or overreaching, grave inconvenience amounting to deprivation of a day in court, or contravention of a strong public policy of the forum. Carnival Cruise Lines, Inc. v. Shute extended Bremen to a non-negotiated form contract, enforcing a Florida clause printed on a cruise ticket against Washington passengers, and reasoned that such clauses have "salutary effects" in sparing a nationwide business from suit everywhere its customers live.

The procedural mechanics come from Atlantic Marine Constr. Co. v. United States Dist. Court, and getting them wrong is a common and avoidable error. The Court held that a forum-selection clause designating another federal district is enforced by transfer under 28 U.S.C. § 1404(a) — not by dismissal under § 1406 or Rule 12(b)(3), because a clause does not make an otherwise-statutorily-proper venue "wrong" under § 1391. Where the clause designates a state or foreign forum, the vehicle is forum non conveniens. And the clause reallocates the § 1404(a) calculus: the plaintiff's choice of forum "merits no weight," the party defying the clause bears the burden of showing transfer is unwarranted, and private-interest factors are treated as having been settled by contract, leaving only public-interest factors — which "will rarely defeat a transfer motion." Atlantic Marine also confirmed that the Van Dusen rule carrying the transferor's choice-of-law rules does not apply when transfer is ordered to enforce a valid clause.

Sequencing and the alternative exits

A corporate defendant with several threshold defenses can usually choose the order in which the court addresses them, and the choice is tactical.

Ruhrgas AG v. Marathon Oil Co. holds that there is no rigid jurisdictional hierarchy: a district court may dismiss for lack of personal jurisdiction without first resolving subject-matter jurisdiction. The case arose from a removed suit in which the subject-matter question — whether the claims raised a substantial federal question — was novel and difficult, while the personal-jurisdiction question as to the German defendant was straightforward. The Court held that "in most instances subject-matter jurisdiction will involve no arduous inquiry" and should be addressed first as a matter of practice, but that where the personal-jurisdiction issue is simpler and the subject-matter issue is difficult and state-sensitive, "judicial economy" permits the reverse order. For a foreign parent that has been dragged into a removed case, Ruhrgas is the authority for asking the court to take the easy exit.

Sinochem Int'l Co. v. Malaysia Int'l Shipping Corp. goes a step further: a court may dismiss on forum non conveniens grounds without first resolving either subject-matter or personal jurisdiction, because a forum non conveniens dismissal is a non-merits determination that "denies audience to a case on the merits." Where jurisdictional discovery would be burdensome and an adequate foreign forum plainly exists, this is the cheapest route out.

The forum non conveniens standard itself comes from Gulf Oil Corp. v. Gilbert, which supplies the private-interest factors (relative ease of access to proof, availability and cost of witnesses, view of the premises, enforceability of a judgment, and all other practical problems) and the public-interest factors (administrative congestion, jury duty burdens, local interest in the controversy, and the court's familiarity with the governing law). Piper Aircraft Co. v. Reyno adds the two points that decide most such motions involving foreign entities: a plaintiff's choice of forum deserves substantially less deference when the plaintiff is foreign, and the possibility of a change in substantive law — including a less generous remedial regime abroad — does not bar dismissal so long as the alternative forum is adequate.

The alternative exits are worth cataloguing, because dismissal for want of personal jurisdiction is often not the best outcome. It is without prejudice, and the plaintiff may simply refile where jurisdiction exists.

Note the interaction between jurisdiction and venue for entity defendants. § 1391(c)(2) deems an entity to reside, for venue purposes, in any district in which it is subject to personal jurisdiction — so a corporate defendant that loses the jurisdictional fight has usually lost venue along with it, and one that wins may defeat both. That coupling makes the jurisdictional motion the more valuable of the two.

Litigating the motion

Burden and standard of proof. The plaintiff bears the burden of establishing jurisdiction over each defendant, on each claim. Where a Rule 12(b)(2) motion is decided on the papers, the circuits generally require only a prima facie showing, with uncontroverted pleading allegations and affidavits read in the plaintiff's favor and factual conflicts resolved against the movant. If the court holds an evidentiary hearing, or defers the question to trial, the standard rises to preponderance of the evidence. Some circuits use an intermediate standard where limited discovery has occurred but no hearing is held.

That structure creates a genuine tactical choice for a corporate defendant. A company with clean declarations — a general counsel's affidavit establishing state of incorporation, headquarters location, absence of forum offices or employees, and the absence of any forum connection to the transaction — may prefer a hearing, because the higher standard and the court's ability to weigh evidence favor it. A defendant whose contacts are messy usually prefers the paper record, because a prima facie ruling denying the motion is not a final determination and the defense may be re-raised at trial or on a later motion where the standard is preponderance. Preserve that right expressly in the opposition; courts will treat a prima facie denial as provisional if asked.

Declarations, not argument. Corporate jurisdictional motions are won on facts a declarant can swear to: state of incorporation; the location of the officers who direct, control, and coordinate the business (the Hertz nerve-center framing Daimler borrowed); absence of forum property, offices, employees, bank accounts, and registration; the identity of any registered agent and the statute under which it was appointed; total revenue and the forum share; and the transaction facts — where the contract was negotiated, executed, and performed, who solicited whom, and where the product was designed, manufactured, sold, and delivered. Volume figures are largely harmless to a defendant after BNSF, so do not omit them; a plaintiff who extracts them later will argue concealment.

Jurisdictional discovery. Courts allow targeted discovery where the plaintiff makes a threshold showing that it could plausibly establish contacts, and deny fishing expeditions. A request tied to a specific theory — the identity and control of the forum distributor, the parent's role in negotiating the contract, the targeting and volume of forum sales of the specific product — is usually granted; "we wish to explore the defendant's contacts" is usually denied. Where general jurisdiction is the only theory, argue that discovery should be denied outright after Daimler and BNSF: no volume of in-state contacts can matter unless the forum is the place of incorporation or the principal place of business, which converts the discovery dispute into a legal one. But respond to what is ordered — Insurance Corp. of Ireland is the price of refusal.

Claim-by-claim and defendant-by-defendant. Bristol-Myers Squibb requires the analysis to be run separately for each plaintiff's claim and each defendant. In a multi-plaintiff or multi-entity case, brief the categories separately and ask for partial dismissal; a court that would not dismiss the whole case will often dismiss the nonresident plaintiffs' claims or the foreign parent.

Appellate posture. A denial of a Rule 12(b)(2) motion is not immediately appealable as of right, and mandamus is rarely granted. The realistic paths are certification under 28 U.S.C. § 1292(b), a renewed motion at summary judgment or trial under the preponderance standard, or the issue preserved for appeal after judgment. Plan the record accordingly: a defendant that wants the higher standard should build the evidentiary record early.

Practice checklist

1. Start with the charter documents. Place of incorporation and principal place of business are the only two paradigm general-jurisdiction forums after Daimler. If neither is the forum, general jurisdiction is off the table absent the Perkins exceptional case.
2. Read the forum state's registration statute, in the version in force when the defendant registered. Mallory turned on Pennsylvania's express consent-to-general-jurisdiction language. Most statutes lack it, and a generic agent-appointment requirement should not be read as all-purpose consent after Daimler.
3. Confirm the service authority. Rule 4(k)(1)(A) plus the state long-arm, a federal nationwide-service statute, or Rule 4(k)(2). Omni Capital is a complete defense where none exists.
4. Argue the long-arm statute before the Constitution where the statute enumerates acts rather than tracking due process.
5. Run relatedness claim by claim and plaintiff by plaintiff. Bristol-Myers Squibb forbids the sliding scale; unconnected in-state sales do not support a nonresident plaintiff's unconnected claim.
6. *Test the Ford pattern. In-state marketing, sales, and servicing of the same product line*, plus a forum resident injured in the forum, is the winning plaintiff configuration. "Relate to" is disjunctive but "incorporates real limits" and is not a but-for test.
7. For component and foreign manufacturers, brief the forum's stream-of-commerce rule. McIntyre produced no majority, so circuit and state precedent controls; pair Goodyear's holding that product flow cannot support general jurisdiction with McIntyre's targeting language.
8. For corporate-family theories, plead or attack specific facts. Alter ego survives; Daimler killed agency as a route to general jurisdiction. Specific-jurisdiction agency must be transaction-specific and control-based.
9. Look for consent in the contract. Forum-selection clauses (Bremen, Carnival Cruise) and agent-appointment clauses (Szukhent) are enforceable, and a clause designating another federal district is enforced by § 1404(a) transfer under Atlantic Marine, not dismissal.
10. Choose the sequence. Ruhrgas permits deciding personal jurisdiction before subject-matter jurisdiction; Sinochem permits forum non conveniens before either.
11. Decide whether you want a hearing. Prima facie on the papers versus preponderance at a hearing is a choice, and it should be made before the declarations are drafted.
12. Do not stonewall jurisdictional discovery. Insurance Corp. of Ireland allows the court to establish the jurisdictional facts against a resisting party under Rule 37.
13. Preserve the defense. Raise Rule 12(b)(2) in the first Rule 12 motion or the answer; removal does not waive it, but merits litigation and counterclaims can.

Frequently asked questions

Where is a corporation subject to general jurisdiction? Its place of incorporation and its principal place of business — the two "paradigm" forums Daimler identified, borrowing the framing from the diversity-citizenship analysis in Hertz Corp. v. Friend. Daimler's footnote 19 reserved an exceptional case in which operations elsewhere might render a corporation at home, and Perkins remains its only illustration: a company whose real operational center had temporarily relocated to Ohio. BNSF confirms that large in-state operations — there, 2,000 employees and 2,061 miles of track — are not such a case.

Doesn't a company with huge in-state sales have to answer for anything there? No, and that is the most common misconception in current practice. Daimler held the question is not whether the in-forum contacts are "continuous and systematic" but whether the corporation's affiliations make it "essentially at home," measured against its nationwide and worldwide activities. Bristol-Myers Squibb then held that extensive in-state sales cannot support a nonresident plaintiff's claim that has no forum connection, rejecting California's sliding scale. Volume alone establishes nothing.

Does registering to do business in a state subject a corporation to suit there on any claim? It depends entirely on the statute's text. Mallory upheld Pennsylvania's scheme against a due-process challenge because the statute expressly provided that qualification permits Pennsylvania courts to exercise general jurisdiction, and because Pennsylvania Fire — never overruled — holds that a state may take a registrant at its word. But the Court fractured, Justice Alito's concurrence flagged an undecided dormant Commerce Clause objection left for remand, and most states' registration statutes contain no comparable consent language. Under a generic statute, treating registration as all-purpose consent would resurrect the doing-business test Daimler rejected. Read the statute.

What is the current stream-of-commerce rule? There is no national rule. Asahi split four to four between Justice O'Connor's "stream of commerce plus" — requiring additional conduct showing intent to serve the forum market, such as forum-directed design, advertising, customer-service channels, or a distributor acting as sales agent — and Justice Brennan's view that awareness of marketing in the forum through the regular flow of commerce suffices. McIntyre produced a four-Justice plurality, a two-Justice concurrence declining to announce a rule, and a three-Justice dissent, leaving the split intact. Brief the forum circuit's or state's precedent.

*How do Bristol-Myers Squibb and Ford fit together? Bristol-Myers Squibb bars jurisdiction where the plaintiff, the injury, and the transaction have no forum connection, regardless of the defendant's unrelated in-state business. Ford permits jurisdiction where the defendant systematically marketed, sold, and serviced the same product line in the forum and a forum resident was injured there, even though the specific vehicle was first sold elsewhere. Ford* holds "arise out of or relate to" is disjunctive, so no causal chain is required — but it also says the phrase "does not mean anything goes" and "incorporates real limits."

Can a parent be sued based on its subsidiary's forum contacts? Only on traditional alter-ego grounds, or through genuine agency as to the specific transaction. Daimler rejected the Ninth Circuit's agency test for general jurisdiction — imputation whenever the subsidiary performs services important enough that the parent would otherwise perform them itself — because it "stacks the deck" and would always produce jurisdiction. Ordinary incidents of ownership, shared branding, and parental oversight are not enough. Footnote 20 left agency open for specific jurisdiction, where it must be control-based and transaction-specific.

Does removing a case waive a corporate defendant's jurisdictional objection? No. Removal is not consent, and the removed defendant may move under Rule 12(b)(2). The defense is lost under Rule 12(h)(1) by omission from a pre-answer Rule 12 motion or from the answer, and can be forfeited by conduct — counterclaims, broad merits discovery, or extended delay.

Can a court reach a foreign corporation with United States contacts spread across many states but concentrated in none? Rule 4(k)(2) is designed for exactly that. For a claim arising under federal law, against a defendant not subject to jurisdiction in any single state's courts of general jurisdiction, service establishes jurisdiction if the exercise is consistent with the Constitution — and the contacts assessed are national. The provision was Congress's answer to Omni Capital, and it is the most frequently overlooked tool in the rule.

What happens if the defendant refuses jurisdictional discovery? Insurance Corp. of Ireland v. Compagnie des Bauxites de Guinee approved a Rule 37 sanction establishing the jurisdictional facts against foreign insurers who resisted discovery on their forum contacts through repeated orders. Because personal jurisdiction protects a waivable liberty interest rather than limiting federal power, it can be lost this way — unlike subject-matter jurisdiction, which no sanction or consent can supply.
