After a bill becomes a law, various executive agencies and independent administrative agencies issue administrative regulations and rules to implement the law.   Congress can also authorize the President to make rules and regulations, a power he usually delegates to executive agencies under his control.   These regulations, often referred to as "administrative law" or "bureaucratic law," are found in the Federal Register and the Code of Federal Regulations.   Together these two publications contain a current compilation of all the rules and regulations which are issued by the federal agencies and the executive departments.
