On January 16, the Florida Supreme Court released an opinion in Advisory Opinion to the Governor re: Implementation of Amendment 4, the Voting Restoration Amendment, SC19-1341. The opinion construes the initiative passed by the voters in November 2018, which ended the ban on ex-felons registering to vote.
The Governor had requested the Florida Supreme Court to construe the amendment. The Florida Supreme Court unanimously agreed that the initiative does not let any ex-felon register until he or she has paid all fines, court costs, and restitution. One judge joined the majority opinion but expressed disagreement with the majority opinion on how such questions are to be decided, and whether the words in the initiative stand alone, or whether courts also need to look at the campaign materials to discern how to interpret an initiative.
The Florida Supreme Court opinion does not bear on the question of whether individuals unable to pay fines, court costs, and restitution can register anyway, under the U.S. Constitution. That question is pending in the Eleventh Circuit in Hand v DeSantis, 18-11388.
