CSS/PMS Political Science | Judicial Review: Ultimate Constitutional Check over Legislative Overreach
Judicial Review ensures constitutional supremacy through judicial scrutiny of legislative and executive actions for legal validity and institutional balance. From a CSS/PMS political science standpoint, it is indispensable for constitutionalism, the rule of law, and protecting fundamental rights.

Introduction
Every democratic state requires institutions that can prevent the misuse of power and ensure that government actions remain within constitutional limits. While the legislature makes laws and the executive implements them, there must be an independent authority capable of determining whether these laws and actions comply with the constitution. This authority is exercised by the judiciary through the mechanism of Judicial Review. Judicial Review is one of the most significant features of modern constitutional democracy. It empowers courts to examine laws, executive actions, and governmental decisions to determine whether they are consistent with the constitution. If a law or action violates constitutional provisions, courts may declare it unconstitutional and therefore invalid. Through Judicial Review, courts protect fundamental rights, uphold constitutional supremacy, maintain the rule of law, and ensure that public authorities remain accountable. For this reason, Judicial Review is often regarded as the guardian of the constitution and one of the strongest safeguards against arbitrary governance.
Definitions
Judicial Review is the power of courts to examine laws and government actions and declare them unconstitutional if they violate the constitution.
According to Edward S. Corwin:
“Judicial Review is the power of a court to pass upon the constitutionality of legislative acts.”
According to John Marshall:
“It is emphatically the province and duty of the judicial department to say what the law is.”
This principle was established in the landmark case of Marbury v. Madison and forms the foundation of modern Judicial Review.
Meaning of Judicial Review
Judicial Review refers to the authority of courts to examine whether laws, policies, executive orders, and governmental actions conform to constitutional requirements. It allows judges to interpret the constitution and determine whether public authorities have acted within the limits of their powers.
The essence of Judicial Review lies in the idea that the constitution is the supreme law of the state. Therefore, no law passed by the legislature and no action taken by the executive can be allowed to contradict constitutional provisions. Whenever such a conflict arises, courts have the power to intervene and uphold the constitution.
In simple terms, Judicial Review ensures that no institution, individual, or government authority is above the constitution.
Characteristics of Judicial Review
Constitutional Basis
Judicial Review derives its authority from the constitution, either through explicit constitutional provisions or through judicial interpretation. It gives courts the legal power to examine whether laws and governmental actions comply with constitutional principles. Without a constitutional foundation, Judicial Review cannot function effectively.
Supremacy of the Constitution
A fundamental characteristic of Judicial Review is that it upholds the constitution as the highest law of the land. It ensures that all laws, policies, and governmental decisions remain subordinate to constitutional provisions. This strengthens constitutional governance and legal stability.
Power of Constitutional Interpretation
Judicial Review enables courts to interpret constitutional provisions and determine their meaning in practical situations. When constitutional disputes arise, judges clarify ambiguities and provide authoritative interpretations. This helps ensure consistent application of constitutional principles.
Check on Government Power
Judicial Review serves as an important check on the powers of the legislature and executive. It prevents public authorities from acting beyond the limits established by the constitution. In this way, it discourages arbitrary decision-making and misuse of authority.
Protection of Fundamental Rights
One of the most significant features of Judicial Review is the protection of fundamental rights and freedoms. Courts can invalidate laws and actions that infringe upon constitutional rights. This ensures that citizens remain protected from unlawful state interference.
Independence of the Judiciary
The effectiveness of Judicial Review depends upon an independent judiciary. Judges must be free from political pressure and external influence so that they can make impartial decisions based solely on law and constitutional principles.
Binding Nature of Decisions
The decisions of superior courts exercising Judicial Review are legally binding on public authorities and government institutions. These decisions must be implemented and respected by all branches of government. This ensures legal certainty and constitutional compliance.
Promotion of the Rule of Law
Judicial Review strengthens the rule of law by ensuring that everyone, including government officials, remains subject to legal limitations. It promotes accountability, transparency, and fairness within the political system.
Scope of Judicial Review
The scope of Judicial Review refers to the areas in which courts can examine and assess governmental actions for constitutional compliance.
Review of Legislative Acts
Courts can review laws passed by the legislature to determine whether they are consistent with the constitution. If a law violates constitutional provisions, courts may declare it unconstitutional.
Review of Executive Actions
Executive orders, administrative decisions, and governmental policies may also be reviewed by courts. This ensures that executive authorities exercise their powers lawfully.
Protection of Fundamental Rights
Courts may review any action that affects the constitutional rights of citizens. If a person’s rights are violated, Judicial Review provides a mechanism for legal protection and remedy.
Resolution of Constitutional Disputes
Judicial Review allows courts to resolve disputes involving constitutional interpretation. This is particularly important when conflicts arise between different branches of government.
Limitation of Public Authority
Courts ensure that public officials and institutions act within the powers granted to them by the constitution and the law. Actions that exceed legal authority may be declared invalid.
Historical Evolution of Judicial Review
Early Foundations
The idea that rulers should be subject to law can be traced to ancient and medieval legal traditions. Over time, constitutionalism developed the principle that governmental power should be limited by higher legal norms.
Development in England
Early English legal thinkers contributed to the concept of constitutional limitations on governmental authority. However, because the British constitutional system is based largely on parliamentary sovereignty, Judicial Review remained relatively limited.
Emergence in the United States
Modern Judicial Review emerged in the United States through the landmark case of Marbury v. Madison.
In this case, Chief Justice John Marshall declared that it was the duty of courts to determine whether laws were consistent with the constitution. This decision established Judicial Review as a central principle of constitutional governance.
Global Expansion
During the twentieth century, Judicial Review spread across many constitutional democracies. Countries such as India, Germany, South Africa, and Pakistan incorporated Judicial Review into their constitutional frameworks.
Today, Judicial Review is recognized as an essential component of democratic constitutionalism worldwide.
Advantages of Judicial Review
Protection of Fundamental Rights
Judicial Review serves as a powerful mechanism for protecting the rights and freedoms of citizens. Whenever a law or government action infringes upon constitutional rights, courts can intervene and provide remedies. This helps ensure that individual liberties remain protected.
Prevention of Abuse of Power
One of the greatest advantages of Judicial Review is that it prevents the misuse of governmental authority. Public officials know that unconstitutional actions may be challenged before the courts. This discourages arbitrary exercises of power and promotes responsible governance.
Maintenance of Constitutional Supremacy
Judicial Review ensures that the constitution remains the supreme law of the state. It prevents legislatures and executives from adopting measures that conflict with constitutional provisions. This contributes to political stability and constitutional continuity.
Strengthening Democracy
Democracy requires more than elections; it also requires adherence to constitutional principles. Judicial Review strengthens democracy by ensuring that elected governments operate within legal boundaries and remain accountable for their actions.
Protection of Minority Rights
Minority groups may sometimes face discrimination or unfair treatment through legislation or policy decisions. Judicial Review helps protect these groups by ensuring that constitutional guarantees apply equally to all citizens.
Promotion of the Rule of Law
Judicial Review reinforces the principle that all individuals and institutions are subject to the law. It promotes fairness, predictability, and equal treatment under the legal system, thereby strengthening public trust in governance.
Resolution of Constitutional Disputes
Conflicts frequently arise between state institutions regarding their powers and responsibilities. Judicial Review provides a peaceful and lawful mechanism for resolving such disputes and maintaining institutional harmony.
Preservation of Separation of Powers
Judicial Review helps maintain a balance among the legislature, executive, and judiciary. By ensuring that each branch operates within its constitutional limits, it prevents the concentration of excessive power in any one institution.
Enhancement of Public Confidence
Citizens are more likely to trust government institutions when there is an independent judiciary capable of reviewing governmental actions. Judicial Review reassures the public that unconstitutional actions can be challenged and corrected.
Adaptation to Modern Challenges
Modern societies face new issues such as digital privacy, environmental protection, artificial intelligence, and national security concerns. Judicial Review enables constitutional principles to be applied to these evolving challenges and ensures that constitutional governance remains relevant.

Example: Constitutional courts in Germany play an important role in maintaining constitutional democracy and protecting democratic values.
Judicial Review in Pakistan
Judicial Review is an integral part of Pakistan’s constitutional system and plays a significant role in maintaining constitutional supremacy and the rule of law. The superior judiciary, particularly the Supreme Court and High Courts, possesses the authority to review laws and governmental actions to ensure their conformity with the Constitution of Pakistan.
The Constitution provides several mechanisms through which courts can exercise Judicial Review. The High Courts may review executive and administrative actions, while the Supreme Court has the authority to interpret constitutional provisions and resolve constitutional disputes.
Judicial Review in Pakistan has been used to protect fundamental rights, examine the legality of executive decisions, and ensure that public authorities act within their constitutional limits. Through this power, the judiciary acts as a guardian of the constitution and an important check on governmental authority.
At the same time, discussions occasionally arise regarding the appropriate scope of judicial intervention in political and administrative matters. Supporters argue that active Judicial Review strengthens accountability and constitutional governance, while others emphasize the importance of respecting the domains of elected institutions. Despite these debates, Judicial Review remains a vital constitutional mechanism for preserving the rule of law, protecting citizens’ rights, and ensuring constitutional compliance in Pakistan.
Conclusion
Judicial Review is one of the most important pillars of constitutional democracy. It empowers courts to ensure that laws, policies, and governmental actions remain consistent with the constitution. By protecting fundamental rights, preventing abuse of power, maintaining constitutional supremacy, and strengthening the rule of law, Judicial Review acts as a powerful safeguard against arbitrary governance. Since its formal establishment through Marbury v. Madison, Judicial Review has become an essential feature of democratic systems across the world. In the contemporary era, it continues to play a crucial role in addressing constitutional disputes, protecting individual freedoms, and preserving democratic governance.
