Here are the materials, including the opinion:
Here is the opinion in State Bar of Arizona v. Lang (Ariz. App.):
Randy D. Lang, a nonmember of the State Bar of Arizona, was enjoined from practicing law in Arizona based on evidence that he repeatedly engaged in the unauthorized practice of law. We hold that a person who presents himself as an attorney based in an Arizona office engages in the unauthorized practice of law unless he has been admitted to practice before the Arizona Supreme Court, even if he has been admitted to practice in a tribal court within the boundaries of Arizona. The supreme court rules that compel this conclusion violate neither the First Amendment nor principles of tribal sovereignty. We further conclude that the superior court properly granted the State Bar of Arizona’s motion for summary judgment, and that the injunction is reasonable in its scope. We therefore affirm.
