Engle v. Isaa

456 U.S. 107 (1982)

Facts

Defendants (D), Isaac, Hughes, and Bell claimed that their constitutional rights were violated at their respective homicide trials because the State was not required to disprove their claim of self-defense. None of the Ds challenged the constitutionality of the self-defense instruction at trial, and this was a violation of Ohio Rule of Criminal Procedure 30, which requires contemporaneous objections to jury instructions. D filed a federal habeas proceeding to litigate the matter.
