In carrying out their functions government bodies frequently enter into contractual arrangements, both with private persons and with other public authorities. Like private individuals, for example, they make leases, employment contracts, and contracts of procurement to obtain the goods and services they require. Frequently they make contracts with the public in the course ofproviding public services and amenities – for example, in running public transport services, or in providing facilities such as recreation centres or museums to the public on payment of a fee. In addition, the government uses contract as a method ofcontrolling behaviour as an alternative to enacting regulations. It may, for instance, control the behaviour of those granted licences to trade or carry on other activities through contractually stipulated conditions
