New York’s highest court on Thursday ordered a reargument in a case over whether the state’s fantasy sports law breaches an anti-gambling provision in the state constitution, driving speculation that judges could be deadlocked over the legal challenge.

The decision comes more than a week after New York state was in court defending the 2016 law, which outlined consumer safeguards and set up a scheme for the registration and taxation of fantasy sports. In those contests, fantasy sports participants select teams of real-world athletes and compete against each other based on how well their roster performs.
