*Coal Mines Act (1930):
‘The Act established a cartel system based upon the principle coalfields and provided also for measures of compulsory amalgamation of collieries. The cartel system was progressively refined and was instrumental in stabilising prices in a declining market for coal. Drafting deficiencies in the original legislation, however, pre-empted compulsory amalgamations. The Act was representative of a general trend towards state intervention in industry and provided the framework for the war-time regulation of the coal industry after 1939’.
