Berlin was called during the 1920 expansion of its municipal boundaries) as well as Baden, Rhineland-Palatinate and Württemberg-Hohenzollern within one year of its promulgation. However, because the occupation of Berlin could be ended only by a quadripartite agreement, Berlin remained an occupied territory under the formal sovereignty of the allies. Hence, the Basic Law was not fully applicable to West Berlin. On 4 August 1950, the House of Representatives, the city's legislature, passed a new constitution, declaring Berlin to be a state of the Federal Republic and the provisions of the Basic Law as binding law superior to Berlin state law (Article 1, clauses 2 and 3). However, that became statutory law only on 1 September and only with the inclusion of the western Allied provision according to which Art. 1, clauses 2 and 3, were deferred for the time being; the clauses became valid law only on 3 October 1990 (the day of Germany's unification). It stated: Article 87 is interpreted as meaning that during the transitional period Berlin shall possess none of the attributes of a twelfth Land. The provision of this Article concerning the Basic Law will only apply to the extent necessary to prevent a conflict between this Law and the Berlin Constitution....In the German translation the respective clause of the Kommandatura Ordinance reads as follows: "Die Bestimmungen dieses Artikels (87) betreffend das Basic Law, finden nur in dem Maße Anwendung, als es zwecks Vorbeugung eines Konflikts zwischen diesem Gesetz und der Berliner Verfassung erforderlich ist".

Decision of the Constitutional Court of the Federal Republic of Germany BVerfG, 25.10.1951 – 1 BvR 24/51 (Der Grundrechtsteil des Bonner Basic Lawes gilt auch in West-Berlin.) , on: OpinioIuris: Die freie juristische Bibliothek , retrieved on 2 May 2012. Thus, civic liberties and personal rights (except for the privacy of telecommunications) guaranteed by the Basic Law were also valid in West Berlin. In addition, West German federal statutes could only take effect in West Berlin with the approval of the city's legislature. The ambiguous legal status of the city, then still legally styled as Greater Berlin (although technically only comprising the western sectors), meant that West Berliners were not eligible to vote in federal elections. In their notification of permission of 12 May 1949 the three western military governors for Germany explained their proviso in No. 4, as follows: A third reservation concerns the participation of Greater Berlin
