The Michigan Supreme Court on Friday denied a request to extend the deadline for drawing new legislative and congressional maps despite a delay in census redistricting data.

The Independent Citizens Redistricting Commission, whose members have been meeting since September 2020, asked the court in April to allow for more time to draw the maps.

The current deadline for an initial proposal is Sept. 17, but the U.S. Census Bureau does not expect to have tabulated data ready for the public until Sept. 30. The commission asserts that the census data is necessary to draw fair and lawful maps.

With its decision, the Supreme Court declined to protect the commission from lawsuits due to any delays. In a statement, justices acknowledged that the commission’s lawyers have already said the commission will operate on a delayed schedule, with or without permission.

The commission was established by voters in 2018 to limit gerrymandering by having randomly selected Michigan residents, representing balanced political alignments, draw voting district boundaries every 10 years instead of the Legislature. The release of census data was delayed from a March 31 deadline because of the pandemic.

The court acknowledged that it believes the commission has been working diligently and through no fault of its own has been put in a difficult position to present fair voting maps, but said there isn’t a sufficient legal reason to preemptively extend the deadline.

Lawyers for the commission and Secretary of State Jocelyn Benson have said they will try to propose new maps by Dec. 11 and have them finalized by Jan. 25, three months after the original Nov. 1 deadline set by the state’s constitution.
