Commercial law (also known as business law) is the body of law that governs business and commercial transactions. It is often considered to be a branch of civil law and deals with issues of both private law and public law.
Commercial law includes within its compass such titles as principal and agent; carriage by land and sea; merchant shipping; guarantee; marine, fire, life, and accident insurance; bills of exchange and partnership. It can also be understood to regulate corporate contracts, hiring practices, and the manufacture and sales of consumer goods.
Various regulatory schemes control how commerce is conducted, particularly vis-a-vis employees and customers. Privacy laws, safety laws (e.g., the Occupational Safety and Health Act in the United States), and food and drug laws are some examples.
