A federal judge has agreed to add potentially hundreds of thousands of people to a lawsuit challenging a Florida statute requiring felons to pay outstanding "legal financial obligations" to vote.

U.S. District Judge Robert Hinkle issued an order Tuesday after saying last week he intended to grant class certification to plaintiffs, who allege that the 2019 law amounts to an unconstitutional "poll tax."

The statute, passed by Republican lawmakers and signed by Gov. Ron DeSantis, was aimed at implementing a 2018 constitutional amendment granting voting rights to felons who have completed their sentences.
