22-10286
9th Cir.Nov 15, 2024Background
- Charles Porter was convicted of various sexual assault offenses after attempting to rape T.D., a male acquaintance, in Yosemite National Park.
- The district court admitted testimony from Porter’s former girlfriend, A.H., who alleged Porter had previously sexually assaulted her.
- The testimony was admitted under Federal Rule of Evidence 413, allowing evidence of other sexual assaults in sexual assault cases.
- Porter challenged the admission of this testimony, arguing it did not meet Rule 413 requirements and was unfairly prejudicial under Rule 403.
- The Ninth Circuit Court reviewed the district court’s application of Rules 413 (de novo) and 403 (for abuse of discretion).
- The Ninth Circuit affirmed both the application of these evidentiary rules and Porter’s conviction.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of A.H.'s prior assault testimony under Rule 413 | Porter's prior acts not sexual assault; testimony unreliable | A.H.'s testimony details repeated nonconsensual sex by Porter | Testimony admissible under Rule 413 |
| Whether admission of A.H.'s testimony was unfairly prejudicial under Rule 403 | Testimony more prejudicial than probative | Testimony probative, fits Rule 403 balancing | District court did not abuse its discretion |
| Necessity and relevance of A.H.'s testimony | Testimony unnecessary, duplicative | Needed to corroborate T.D.'s account | Testimony allowable as helpful but not required |
| Government's use of testimony to attack sexual preference | Testimony unfairly denigrated Porter | Testimony used to show propensity, not preference | Government did not improperly use testimony |
