An Iranian American advocacy group filed a federal lawsuit on Thursday challenging the legality of the seven-month war in Iran.
The suit asks a federal judge to declare that Congress never declared or authorized the conflict.
The filing argues that the military action violates constitutional requirements for congressional approval.
Legal experts say the case could test the limits of executive war powers.
The group seeks a court ruling that would halt further military operations against Iran.
Government lawyers have not yet responded to the complaint.
The lawsuit adds to a growing debate over presidential authority in prolonged overseas conflicts.
