Many administrative agencies. such at the Federal Trade Commission and the Internal Revenue Service, have the power to promulgate regulations that have the force of law, to conduct investigations of potential violations of those reglations, to bring charges against people for allegedly violating the regulations, and to try the cases in their own administrative law courts presided over by administrative law judges who are agency employees. Does this fit in with the Constitutional principle of separation of powers? What safeguards, if any, are advisable to protect individual rights?
