the Brandt Administration. The consumer's right of withdrawal in case of hire purchase was strengthened in March 1974, and fixed prices for branded products were abolished by law in January that same year, which meant that manufacturers' recommended prices were not binding for retailers. In addition, a progressive anticartel law was passed. A 1969 law on explosive materials was supplemented by two orders; the first (made in November 1969) establishing a committee of experts for explosive materials, while the second order (made the following month) included details for the implementation of the law on explosive materials. An Act of December 1959 on the peaceful use of nuclear energy and protection against its dangers was amended by an Act of June 1970 that established a tax levied for the costs for permissions and surveillance measures. The Law on Compensation for Measures of Criminal Prosecution and Penalties, passed in March 1971, provided for standardized compensation in certain situations. In addition, the budget for communications was increased. The federal crime-fighting apparatus was also modernised, while a Foreign Tax Act was passed which limited the possibility of tax evasion. A law on explosives (Sprengstoffgesetz) was the subject of two application ordinances (on 17 November 1970 and 24 August 1971) and a general regulatory provision (19 May 1971), which covered respectively the application of the law to nationals of EC Member States, the duty of employers to notify in time the inspection authorities of detonation plans, the interpretation of the purpose and field of application of the law, authorizations for transport of explosives, and control and recognition of training courses on work with explosives. Taking into account the enormous high peaks of air traffic noise and its concentration at a limited number of airports, the Law for Protection against Aircraft Noise of 1971 sought to balance two conflicting demands, the first being the legitimate demand by industry, business and the public for an efficient air-traffic-system, and secondly, the understandable and by no means less legitimate claims of the affected people for protection and compensation. The legislation regulated the establishment of so-called "Lärmschutzzonen" (protection areas against aircraft noise) for all 11 international airports and for those 34 military airports used for jet air craft, and the law also authorised the Federal Department of the Interior to decree protection areas for each of those mentioned airports with approval by the "Bundesrat", the representation of the German Federal
