Alexis de Toqueville once observed that a key feature of American government was the decentralized character of administration. “Written laws exist in America,” he wrote, “and one sees the daily execution of them; but although everything moves regularly, the mover can nowhere be discovered. The hand which directs the social machine is invisible.”2Administrative law is the body of law that allows for the creation of public regulatory agencies and contains all of the statutes, judicial decisions and regulations that govern them. Administrative agencies implement their powers in the form of rules, regulations, orders and decisions. State medical boards are the regulatory agencies responsible for the licensure and discipline of physicians. They grant the right to practice medicine in the form of a medical license and each state has Medical Practice Act that governs and defines the practice of medicine. The medical board is empowered to take action against a doctor for substandard care, unprofessional behavior and other violations as defined by the state Medical Practice Act.Administrative Code governs the licensure and disciplinary process and the State Administrative Procedure Act governs the legal process (due process, discovery, etc.). Regulatory changes are enacted through procedural, interpretive and legislative rules.Both medical practice acts and administrative procedure acts are subject to change. Changes in medical practice acts can redefine what is acceptable practice and what constitutes professional behavior. This can increase the power and control these agencies have over doctors both professionally and socially.
