People v. Lawson

Summary

The New York Court of Appeals reversed the Appellate Term’s order and dismissed the indictment, holding that the People cannot obtain a second opportunity to argue the legality of a traffic stop after having had a full and fair chance to oppose suppression. The Court affirmed that the burden rests on the People to demonstrate the illegality of the conduct and that the suppression court lacked authority to vacate its prior ruling and consider new legal theories. The decision relied on prior precedent emphasizing finality and the “full and fair opportunity” principle.
