United States v. Abel
United States Supreme Court
469 U.S. 45 (1984)
Relevant factsFree
After Abel's cohort Ehle testified against him pursuant to a plea deal, Abel called Mills to testify that Ehle had privately admitted planning to testify falsely, and the prosecution responded by recalling Ehle to testify that Abel, Ehle, and Mills all belonged to a secret prison gang whose members were required to deny its existence and commit perjury for one another, evidence the district court admitted over Abel's objection.
IssueFree
Whether evidence that a witness and a defendant he is testifying for are members of a gang that requires its members to commit perjury for each other is admissible to show the bias of the witness.
