Which body is responsible for the regulation of the practice of law in Mississippi?

The Mississippi Supreme Court is the body responsible for regulating the practice of law in Mississippi. This authority is established by the state constitution, which grants the Supreme Court the power to oversee the admission to the bar and the discipline of attorneys. The court's role includes setting rules for legal practice, establishing standards of professional conduct, and ensuring that lawyers comply with these standards in order to maintain the integrity of the legal profession.

In Mississippi, the Bar Association plays a supportive role in terms of providing resources, continuing education, and professional development for lawyers, but the ultimate authority lies with the Supreme Court. The Attorney General and the State Legislature have specific functions related to legal oversight and public policy, but neither is responsible for regulating the legal profession directly. Thus, the Supreme Court's critical function in establishing and enforcing the rules governing attorneys makes it the correct answer.
