Commission
In law a commission is an act granting a person an office or position. Most commonly this term is used when a public officer appoints a person to a government or military office, but the term also applies to any appointment of an agent by a principal under the law of agency.
A commission is also the letters patent that serve as evidence of the appointment. There have been cases where the validity of a person's appointment has been disputed based on whether or not the commission was properly made and delivered, such as the landmark Marbury v. Madison of the United States Supreme Court.
A commission is also a fee or allowance given to a sales person or agent in exchange for services rendered.
