The Basic Law [Grundgesetz], Germany's Constitution, remains a central point of reference in International Constitutional Law. The instrument has been amended 69 times during the more than 75 years of its application, even surviving groundbreaking political changes like the reunification of West and East Germany. This translation is part of the research project International Constitutional Law (www.verfassungsvergleich.de). All amendments up to and including the 69th Amendment of 25th March 2025 have been translated and included into a consolidated edition. There have been no more amendments until today (6th Sep 2025). This is not an official government document.
