Gamache v. California
2010 U.S. LEXIS 9043
SCOTUS
2010
Read the full case

Background

  • Gamache was convicted of first‑degree murder and sentenced to death.
  • During deliberations, the jury was given a videotape not admitted into evidence.
  • The jury watched the tape twice in full and a third time in part, showing Gamache confessing in graphic terms.
  • California Supreme Court treated the error as trial error, not juror misconduct, and conducted a harmless‑error analysis without applying a presumption of prejudice.
  • The court adhered to Chapman v. California, requiring the State to prove harmlessness beyond a reasonable doubt.
  • Justice Sotomayor, joined by Ginsburg, Breyer, and Kagan, would deny certiorari but cautions about burden allocation potentially affecting outcomes in capital cases.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether the videotape error was harmless beyond a reasonable doubt. Gamache contends the error was prejudicial and not harmless. California treated the error as harmless and followed Chapman. Certiorari denial; harmlessness upheld
Whether California's burden allocation as to harmlessness complied with Chapman. State bears the burden; allocation contravenes Chapman. Burden allocation would not have altered prejudice analysis. Certiorari denial; burden allocation not shown to alter outcome
Whether the potential burden allocation could be outcome‑determinative in capital cases. Allocation can be decisive in capital cases. In this case, it did not change the result. Not dispositive here; concern acknowledged
