Supreme Court of the United States

William A. Shaffer, Plaintiff in Error v. James A. Scudday

January 22, 185760 U.S. 16

Summary

The Court dismissed the writ of error because it lacked jurisdiction to review the Louisiana Supreme Court's judgment. The disputed title depended exclusively on Louisiana law governing competing state-issued patents, rather than on the construction or validity of federal law. The judgment therefore presented no federal question within the Court's appellate jurisdiction.

Holding

  • Federal appellate jurisdiction over the state-court title judgment. The Court had no authority to revise the Louisiana Supreme Court's judgment by writ of error because Shaffer's asserted title depended exclusively on Louisiana law, not on any federal act or federal authority whose validity or construction was at issue.
