Compulsory education is constitutional in the United States. The Supreme Court ruled in 1925 in the case of Pierce v. Society of Sisters that parents have the right to choose the type of education their children receive, but the state also has the authority to require children to attend school. This decision upheld the constitutionality of compulsory education laws, as long as parents have the option to choose between public and private schools. Additionally, the 10th Amendment of the U.S. Constitution gives states the authority to regulate education within their borders, including mandating compulsory education. **

The Air Security Act was rejected by the Federal Constitutional Court because it was deemed to violate the fundamental rights of individuals. The court found that the act's provisions allowing for the shooting down of hijacked planes without warning and the use of lethal force against civilians on board were disproportionate and violated the right to life and human dignity. The court also ruled that the act did not provide sufficient legal safeguards and oversight to prevent abuse of power. As a result, the court declared the act unconstitutional and incompatible with Germany's Basic Law. **

The Socialist Law, implemented in Germany in 1878, was controversial and faced criticism for its restrictions on socialist activities and political freedoms.

A constitutional state is characterized by a framework of laws and principles that establish the powers, duties, and limitations of government institutions. It is governed by a constitution that outlines the rights and freedoms of individuals, the separation of powers, and the rule of law. In a constitutional state, the government is bound by the constitution and must operate within its legal constraints, ensuring accountability and protecting the rights of its citizens. Additionally, a constitutional state typically includes mechanisms for judicial review to uphold the constitution and resolve disputes. **

No, a constitutional monarchy is not unconstitutional.

However, the party itself has not been banned or declared unconstitutional by the German authorities. Ultimately, whether the AfD is considered anti-constitutional is a matter of interpretation and debate. **
