An attorney who’s faced discipline for sending allegedly abusive letters making demands under the Americans with Disabilities Act is facing new charges for the same conduct. He is among at least half a dozen lawyers in the hot seat for alleged ethics violations.

Attorney Omar Weaver Rosales’ name circulated in Texas legal circles during the last legislative session, after he won a key appellate court ruling in his past case dealing with ADA letters. That ruling motivated lawmakers to exclude lawyer-discipline cases from the Texas Citizens Participation Act, the state’s anti-SLAPP law, among other changes to narrow the law.
