Is the power of supreme court to review state actions legislation comes from the supremacy clause of article vi true or false?

True. The power of the Supreme Court to review state actions and legislation is indeed rooted in the Supremacy Clause of Article VI of the U.S. Constitution. This clause establishes that the Constitution and Federal Laws take precedence over state laws, allowing the Supreme Court to ensure that state actions comply with federal law and the Constitution. Thus, the Court can invalidate state legislation that conflicts with federal statutes or constitutional provisions.
