Freedom of contract is the freedom of individuals and groups (such as corporations) to form contracts without government restrictions. This is opposed to government restrictions such as minimum wage, competition law, or price fixing. Through freedom of contract, individuals entail a general freedom to choose with whom to contract, whether to contract or not, and on which terms to contract. (Wikipedia)
