Connecticut officials were granted extension to respond to MGM lawsuit over favoring tribes to develop a third casino in the state, barring out-of-state competitors.

MGM Resorts International filed a lawsuit earlier this month in U.S. District Court in New Haven with Connecticut Gov. Dannel Malloy as a defendant, saying a law he signed that could lead to a third tribal casino, gives the two tribes— the Mashantucket Pequots and the Mohegans—preferential treatment.

The lawsuit also said that the Connecticut bill violated the constitution’s Equal Protection Clause, which bans discrimination based on racial preferences, as well as the Dormant Commerce Clause by favoring a pair of in-state tribes while banning any bids by out-of-state competitors.

MGM President Bill Hornbuckle claimed that his company applied for a casino license in the state after the passage of the act but was rejected.
