A Maine judge ordered the state’s top election official on Wednesday to wait for a U.S. Supreme Court ruling before putting into effect her decision to exclude former President Donald J. Trump from Maine’s Republican primary ballot.

Justice Michaela Murphy of Maine Superior Court said in the ruling that the official, Secretary of State Shenna Bellows, had been forced under Maine law to rule quickly, without the benefit of the high court’s input.

The Supreme Court has agreed to review, at Mr. Trump’s request, an earlier decision by a Colorado court to exclude him from the ballot, and is expected to hear arguments in the case on Feb. 8. Ms. Bellows had cited the Colorado court’s reasoning in her decision.

“The secretary confronted an uncertain legal landscape when she issued her ruling,” Justice Murphy wrote in a 17-page decision, and “should be afforded the opportunity to assess the effect and application” to her ruling of whatever the high court decides.
