WASHINGTON — The Supreme Court on Tuesday blocked rulings from a federal court in Texas that had called for revisions to congressional and state legislative districts in the state after the court found that the districts violated the Constitution and the Voting Rights Act.

The Supreme Court’s brief order, in a long-running dispute over legislative maps drawn after the 2010 census, made it more likely that the 2018 election will be held using maps rejected by a three-judge panel of the Federal District Court for the Western District of Texas, in San Antonio. The Supreme Court’s order will remain in place while it considers the state’s appeal.

The vote was 5 to 4 and divided along ideological lines, with the court’s more conservative members in the majority.

The court in San Antonio had ruled that a congressional district including Corpus Christi denied Hispanic voters “their opportunity to elect a candidate of their choice.” The court rejected a second congressional district stretching from San Antonio to Austin, saying that race had been the primary factor in drawing it.
