Texas Attorney General Ken Paxton is supporting the legal arguments of three attorneys who sued the State Bar of Texas alleging it violated their rights by spending part of their mandatory dues for political and ideological speech.

Paxton’s office filed an amicus brief Friday in the case, McDonald v. Longley, that said the Texas bar is violating its members rights by compelling their financial support for those alleged activities without first getting affirmative consent. The brief said there’s no justification for the bar to force attorneys to fund such activity through mandatory dues. Paxton urged the court to grant the plaintiffs’ motion for partial summary judgment on liability.
