Concept
The Basic Law for the Federal Republic of Germany (Grundgesetz für die Bundesrepublik Deutschland) is the constitution of the Federal Republic of Germany. The West German Constitution was approved in Bonn on 8 May 1949 and came into effect on 23 May after having been approved by the occupying western Allies of World War II on 12 May. It was termed "Basic Law" (Grundgesetz) to indicate that it was a provisional piece of legislation pending the reunification of Germany. However, when reunification took place in 1990, the Basic Law was retained as the definitive constitution of reunified Germany. Its original field of application (Geltungsbereich)—that is, the states that were initially included in the Federal Republic of Germany—consisted of the three Western Allies' zones of occupation, but at the insistence of the Western Allies, formally excluded West Berlin. In 1990, the Two Plus Four Agreement between the two parts of Germany and all four Allies stipulated the implementation of a number of amendments. The German word Grundgesetz may be translated as either Basic Law or Fundamental Law. The term "constitution" (Verfassung) was avoided as the drafters regarded the Grundgesetz as an interim arrangement for a provisional West German state, expecting that an eventual reunified Germany would adopt a proper constitution, enacted under the provisions of Article 146 of the Basic Law, which stipulates that such a constitution must be "freely adopted by the German people". Nevertheless, although the amended Basic Law was approved by all four Allied Powers in 1990 (who thereby relinquished their reserved constitutional rights), it was never submitted to a popular vote, neither in 1949 nor in 1990. However, the Basic Law as passed in 1949 also contained Article 23 which provided for "other parts of Germany" to "join the area of applicability of the Basic Law" which was the provision that was used for German reunification from the constitutional standpoint.
