Civil Aviation Act 1949

The Civil Aviation Act 1949 (12, 13 & 14 Geo. 6. c. 67) was an public and general act of the Parliament of the United Kingdom covering civil aviation. Among other provisions it repealed the Air Navigation Act 1920, set up a Ministry of Civil Aviation Constabulary and formalised the powers of the Minister of Civil Aviation, including those to regulate and establish aerodromes. It was repealed by the Civil Aviation Act 1982, and reinforced the Air Navigation Act 1947. The act was used to defend aircraft carrying opium illegally, because according to the act, if a British aircraft broke the law, it would have, "for the purpose of conferring jurisdiction, be deemed to have been committed in any place where the offender may for the time being be."
