In September 2017, President Trump issued a Proclamation that put substantial limitations on the entry of citizens from six Muslim-majority countries (The White House). A District Court granted a preliminary injunction preventing enforcement of a large part of the Proclamation, and the Court of Appeals for the Ninth Circuit affirmed, for the most part, the District Court's injunction (SCOTUS Blog). President Trump appealed (SCOTUS Blog). "Likely violates" refers to a situation in which the Court makes a decision on the Establishment Clause for the purposes of ruling on the preliminary injunction, but does not make a direct ruling on the proclamation. The Supreme Court is expected to hand down its decision in its current term, but if it does not, the question will resolve as No. See our FAQ to learn about how we resolve questions and how scores are calculated.
