CINCINNATI (AP) — Ohio’s elections chief wants some guidance on how to accommodate blind voters without jeopardizing the process for all others.

A spokesman for Secretary of State Jon Husted says previous rulings have been clear that one set of voters can’t receive accommodations that aren’t available to others.

An appeals court on Monday revived a lawsuit alleging blind Ohio residents have been denied “meaningful access” to the state’s absentee voting system.

Husted has contended that county boards of election already offer special accommodations for blind voters.

A federal judge sided with Husted last year, saying that implementing changes to accommodate the blind would fundamentally alter the entire voting system.

The 6th U.S. Circuit Court of Appeals on Monday reversed that decision and allowed the lawsuit to proceed.
