Stogner V. California

California has brought a criminal prosecution after expiration of the time periods set forth in previously applicable statutes of limitations. California has done so under the authority of a new law that (1) permits resurrection of otherwise time-barred criminal prosecutions, and (2) was itself enacted after pre-existing limitations periods had expired. We conclude that the Constitution's Ex Post Facto Clause, Art. I, §10, cl. 1, bars application of this new law to the present case.
