Constitutional Claim in Federal Court
Farid Farahani and other tenants sued Horizon Management in federal district court. They alleged that joint inspections by company employees and federal housing officers violated their Fourth and Fifth Amendment rights and sought damages directly under those provisions. Horizon moved to dismiss for lack of subject-matter jurisdiction. The court denied the motion because the complaint asserted a right to relief grounded in federal constitutional law.
Spousal Testimony Privilege
Francois Fortier was indicted in federal court on fraud charges. The government subpoenaed his wife, Fatou Fall, to testify about conversations that occurred during their marriage. Fatou declined to testify. The court ruled that the witness-spouse privilege applied in federal court and could not be overridden by the party spouse.
