In April 2015, Crooks broke from both Abrahamson and the conservative majority in a dispute over the election of Patience Drake Roggensack as the court's chief justice. Earlier in 2015, voters had approved a referendum permitting the court's justices to elect their chief justice; throughout Wisconsin's history, the most senior justice had occupied the court's highest office. Crooks condemned Abrahamson's attempts to retain her position, which included a federal lawsuit, but did not support Roggensack's election; instead, he indicated that he would consider seeking the chief justiceship and running for reelection in 2016, an event theretofore considered unlikely.
