Laws can be made by legislatures through legislation (resulting in statutes), the executive through decrees and regulations, or judges through binding precedent (normally in common law jurisdictions). Private individuals can create legally binding contracts, including (in some jurisdictions) arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution (written or unwritten) and the rights encoded therein. The law shapes politics, economics, and society in various ways and serves as a mediator of relations between people.
