In 2019 the Indiana legislature passed a bill deleting the ability of voters to go to state court, to get an extension of the voting hours when an unforeseen emergency occurs.

On July 8, Common Cause Indiana filed a federal lawsuit against the new law. Common Cause Indiana v Lawson, s.d., 1:20cv-1825. Here is the brief.
