A panel of Texas’ Third District Court of Appeals judges will hear arguments Wednesday in a case pitting the State Bar of Texas’ Commission for Lawyer Discipline against an Austin lawyer fighting sanctions over allegedly abusive litigation tactics targeting businesses for Americans with Disabilities Act violations.

The commission said attorney Omar Weaver Rosales engaged in dishonest and frivolous litigation by threatening to sue website operators for baseless ADA violations unless they paid him $2,000 to go away. Rosales himself claims to have suffered injuries while in the military that left him with mental and physical disabilities.
