Can supreme court question the validity of parliament acts in the UK?

In the UK, the Supreme Court does not have the authority to question the validity of Parliament acts due to the principle of parliamentary sovereignty. This principle holds that Parliament is the supreme legal authority, and its laws cannot be overturned by any other body, including the courts. However, the courts can interpret legislation and ensure it complies with existing laws, including the Human Rights Act. Ultimately, while the Supreme Court can influence how laws are applied, it cannot invalidate legislation passed by Parliament.
