The German Environmental Aid (DUH) has announced its intention to file a constitutional complaint against the recently announced Building Modernization Law. This law was published in the Federal Gazette last week and aims to promote the modernization of buildings in Germany. However, the DUH sees legal issues with the law and intends to take legal action to ensure that the government's environmental and climate goals are not compromised. The organization is calling for a review of the legal foundations of the law and aims to assert compliance with environmental standards and climate protection through its lawsuit.
