I want to know the answer to the following question:
Which article stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law"?
All the background I'm provided with is that "The Basic Law of the Federal Republic of Germany, the federal constitution, stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law" (Article 28).". Is that enough to answer the question?
