Here is the unpublished opinion in United States v. War Club.

An excerpt:

We conclude that bylimiting cross-examination of Green’s brother, the district court precluded War Club from developing evidence that Green’s brother had a motive to commit the murder. The court thereby deprived War Club of the “meaningful opportunity to present a complete defense” guaranteed by the Constitution. Holmes v. South Carolina, 547 U.S. 319, 324 (2006) (quoting Crane v. Kentucky, 476 U.S. 683, 690(1986)). Because we cannot say that the error was “harmless beyond a reasonable doubt,” United States v. Boulware, 384 F.3d 794, 808 (9th Cir. 2004) (quoting Chapman v. California, 386 U.S. 18, 24 (1967)), we vacate the conviction and remand for a new trial.
