This document summarizes a legal dispute over the approval of Germany's 2002 Immigration Act. Specifically: - Several states filed a legal challenge arguing the Bundesrat's approval was invalid due to an inconsistent vote from Brandenburg. - During Bundesrat voting, Brandenburg representatives initially voted differently (yes and no) but the president ruled it a yes, approving the act. - The German Constitutional Court ultimately ruled the approval was invalid since Brandenburg did not provide a uniform vote as required. As a result, the immigration act was found to be void due to the lack of proper Bundesrat consent.
