During his relatively short period in office, Luther and his cabinet managed to accomplish the passage of several important laws and international treaties. In foreign trade, the one-sided most-favoured-nation clause that had governed trade between the Allies and Germany lapsed on 10 January 1925, thus reestablishing Germany's sovereignty in trade policy. The tariff law came into force on 12 August 1925, setting up tariffs for industry and agriculture that were based on the tariff rates of the pre-war years. Trade treaties were negotiated with the UK, the Soviet Union, France, Spain and Italy. In domestic tax policy, a tax reform brought relief as taxes on income, capital and land transfer as well as bill stamp duty and sales tax were all lowered. In foreign policy, the cabinet negotiated the Treaty of Locarno with the UK, Belgium, France and Italy (October 1925), which paved the way for Germany's membership in the League of Nations (September 1926). The ministers of the DNVP left the cabinet in protest over Locarno, forcing Luther to set up a new government that took office in January 1926. This government negotiated the "Freundschafts- und Neutralitätsvertrag" with the Soviet Union.
