The U.S. Supreme Court removed a clash over President Donald Trump’s travel ban from its argument calendar and raised the prospect it will dismiss the case, telling the administration and the ban’s challengers to file briefs discussing the impact of a newly revised policy.

The revised policy, issued Sunday and affecting eight countries, supersedes what had been a temporary travel ban affecting six mostly Muslim countries. The court had been scheduled to hear arguments Oct. 10 on the earlier policy.

The one-paragraph order doesn’t preclude the court from re-scheduling the case for argument at a later point in its nine-month term, which formally starts today. The court asked the two sides to discuss whether the dispute before the justices is legally moot given the new policy.

Challengers to the policy say Trump is exceeding his authority under the federal immigration laws and violating the Constitution by targeting Muslims.

Trump says he is acting to protect the country from terrorism. His new order comes after the Department of Homeland Security recommended restrictions, saying particular countries weren’t providing enough information about their citizens who were seeking to enter the U.S.

The new policy adds North Korea, Venezuela and Chad to the list of countries facing at least some restrictions.
