John Conyers of Michigan resigned from the U.S. House on December 5, 2017. Governor Rick Snyder then said the vacancy would be filled on November 6, 2018, meaning that the seat would be vacant for almost eleven months. Some Michigan voters in the 13th district then sued to obtain an earlier special election.
On February 2, the voters filed their 12-page brief. Rhodes v Snyder, e.d., 17cv-14186.
