An attorney disciplinary lawsuit is the latest consequence for an Austin attorney whose abusive litigation tactics in disability discrimination cases already brought a $175,000 sanction and three-year ban from Austin’s federal court.

The latest allegations against solo practitioner Omar Weaver Rosales detail a different sort of misconduct, although still related to the Americans with Disabilities Act, which prohibits discrimination against people with disabilities. The Commission for Lawyer Discipline on Sept. 14 filed an amended disciplinary petition against Rosales after it received eight separate grievances all claiming Rosales was sending abusive demand letters that alleged the recipients’ websites violated the ADA.
