The lawyer for a group of New York Republicans who sued Democrats for allegedly gerrymandering three political maps has formally asked a lower court judge to appoint a “neutral expert” to redraw the congressional map.

The request by the GOP’s attorney, Bennet Moskowitz of New York City, was made Sunday in writing to acting Steuben County Supreme Court Judge Patrick McAllister, who had ruled on March 31 that the three maps were unconstitutionally gerrymandered in favor of Democrats.
