Jurisdiction – Ripeness

Listen to this article

Where a plaintiff has filed a complaint seeking to prevent enforcement of state gambling laws that the plaintiff alleges are preempted by the Commodity Exchange Act, the complaint must be dismissed without prejudice as unripe because the commonwealth has stipulated that it will not file any enforcement action against the plaintiff while a separate proceeding remains pending in state court.

“Plaintiff Robinhood Derivatives, LLC (Robinhood) filed this action against defendants Andrea Joy Campbell, in her official capacity as Attorney General of the Commonwealth of Massachusetts; Jordan Maynard, in his official capacity as Chair of the Massachusetts Gaming Commission; Eileen O’Brien in her official capacity as Commissioner of the Massachusetts Gaming Commission; Bradford R. Hill, in his official capacity as Commissioner of the Massachusetts Gaming Commission; Nakisha Skinner, in her official capacity as Commissioner of the Massachusetts Gaming Commission; and Paul Brodeur, in his official capacity as Commissioner of the Massachusetts Gaming Commission (collectively, the Commonwealth), seeking to enjoin enforcement of state gambling laws which Robinhood alleges are preempted by the Commodity Exchange Act. Robinhood moves for a preliminary injunction barring the Attorney General from enforcing state gaming laws against its sports-event related contracts. The Commonwealth cross-moves to dismiss the case. For the following reasons, the court will allow the Commonwealth’s motion and deny Robinhood’s motion as moot. …

“Robinhood has not shown that its sole federal claim (under Ex Parte Young) is ripe for judicial review. The Commonwealth has stipulated that it will not file any enforcement action against Robinhood while its motion for a preliminary injunction remains pending in the proceeding brought against Kalshi in the Massachusetts courts. There thus is no risk that the Commonwealth will engage in the conduct which Robinhood alleges to be unlawful prior to a decision being issued by a state court of competent jurisdiction. Whether there is a risk that the Commonwealth will engage in that conduct after the state court rules on the motion depends entirely on what that decision proves to be. If the state court denies the Commonwealth’s motion as unlikely to succeed on the merits, for example, it is unlikely that Robinhood — which currently offers sports-related event contracts exclusively through Kalshi — would face any imminent risk of enforcement. If the state court instead allows the Commonwealth’s motion and enjoins Kalshi from conducting gaming-related business in the Commonwealth, Robinhood would lose its existing Massachusetts sports event platform. An inability to prospectively engage in the type of conduct that allegedly puts Robinhood at risk of enforcement would render its Ex Parte Young claim a nullity.

“Robinhood has similarly not shown that it will suffer any hardship if adjudication of its claim is delayed until it ripens. … Here, because the threat of enforcement is (for the reasons discussed above) contingent, any hardship is also necessarily contingent. …

“For the foregoing reasons, defendants’ motion to dismiss is allowed and plaintiff’s motion for a preliminary injunction is denied as moot. The case is dismissed without prejudice for lack of ripeness.”
