Thirty-six former U.S. Justice Department civil rights division lawyers, whose collective service spans the Eisenhower through Obama administrations, are urging a federal appellate court to strike down Florida’s law conditioning the right to vote for individuals with felony convictions on the payment of restitution, fines and fees.

The lawyers, many of whom held high-ranking positions in the division and in the voting section specifically, argued in an amicus brief in the U.S. Court of Appeals for the Eleventh Circuit that under the U.S. Supreme Court’s 2012 decision upholding Obamacare, the state’s pay-to-vote law is an unlawful “tax” on voting that violates the 24th Amendment.
