The right to practice law is considered a fundamental right protected by the Constitution. The U.S. Supreme Court has addressed this issue in several landmark cases. For example, in the case of Supreme Court of New Hampshire v. Piper (1985), the Court held that while states have the authority to regulate the practice of law and set admission requirements, these regulations must not violate the Constitution, including the Due Process and Equal Protection Clauses of the Fourteenth Amendment.

Similarly, in Baird v. State Bar of Arizona (1971), the Supreme Court emphasized that states cannot impose arbitrary or unreasonable restrictions on the right to practice law, as doing so would violate the Fourteenth Amendment.
