House to vote on number of justices
Iowa and Montana filed an 'original action' with the Supreme Court to block a merger between Paramount Skydance and Warner Brothers, valued at $110 billion, and to halt an antitrust enforcement action by 12 Democratic-led states. The Supreme Court has the authority to hear disputes between states directly, and the process involves filing a bill of complaint and potentially appointing a special master.
