Judicial review is a principle that originated in the United States and allows the Supreme Court to review the constitutionality of laws and actions by the government, both at the national and state level. While it primarily protects against unfair actions by the national government, it can also safeguard against unfair actions by state governments. The power of judicial review ensures that government actions adhere to the constitution and maintains the balance of power among the three branches of government.
