Foundations of Judicial Review

Judicial Review: Definition, Principles, and Approaches Introduction Judicial review is one of the most important mechanisms in constitutional law, serving as the primary tool through which courts ensure that all branches of government—including the legislative and executive branches—operate within their constitutional authority. Understanding judicial review requires understanding not only what it is, but also how different legal systems approach it and what it means for the balance of power in government. What is Judicial Review? Judicial review is the process by which courts examine executive, legislative, or administrative actions and determine whether they are lawful. When a court conducts judicial review, it is asking a fundamental question: Does this action comply with the law and the constitution? The most significant power that courts exercise in judicial review is the authority to invalidate. If a court determines that a governmental action—whether a law, regulation, executive order, or administrative decision—conflicts with a higher legal authority (such as a constitution), the court can declare that action invalid and prevent it from being enforced. This power is what makes judicial review genuinely consequential in government. The Separation of Powers Foundation Judicial review operates as a cornerstone of the separation of powers doctrine. This principle holds that governmental power should be divided among three branches—the legislative, executive, and judicial branches—and that no branch may exercise power over another without constitutional authority and due process. Judicial review embodies this principle by empowering courts to strike down actions by the other branches when those actions exceed their constitutional authority. In practical terms, judicial review serves as a crucial check and balance. The legislative and executive branches cannot act arbitrarily or unconstitutionally because they know courts will examine their actions. This creates an important restraint on governmental overreach. General Principles in Different Legal Systems Judicial review does not operate identically everywhere. Different legal traditions have developed distinct approaches to how courts review governmental action. Civil Law vs. Common Law Traditions In common-law systems (such as the United States and United Kingdom), judges have historically played a more creative role in developing law. They can establish new legal principles through their decisions and can discard outdated legal rules when circumstances warrant. This judicial flexibility is built into the DNA of common-law systems. In civil-law systems (found throughout continental Europe and many other regions), judges operate within a more constrained framework. They are expected to apply existing law rather than create it. A civil-law judge cannot simply establish a new legal principle or overturn an established rule; their role is to interpret and apply the law as it exists. This distinction matters enormously for judicial review. It affects how aggressively courts will scrutinize governmental action and how much discretion judges believe they have to strike down laws or policies. Legislative Supremacy vs. Separation of Powers Related to these traditions are two competing constitutional philosophies: Legislative supremacy holds that the legislative body (parliament or congress) possesses ultimate governmental authority. In this view, elected representatives of the people hold the final decision-making power, and courts should defer to legislative choices. Separation of powers, by contrast, limits each branch's authority by dividing power among them. Under this approach, no single branch—including the legislature—may exercise unlimited power. These philosophies lead to radically different approaches to judicial review. A system built on legislative supremacy will be much more hesitant to allow courts to invalidate legislative acts. A system built on separation of powers will be more willing to do so. The Ultra Vires Principle One critical principle that applies across many legal systems is the ultra vires doctrine. "Ultra vires" means "beyond the powers," and the principle holds that public bodies and administrative agencies must act only within the powers that the law has granted to them. When a government body acts beyond its granted authority, courts will invalidate that action as ultra vires. For example, if a statute grants a regulatory agency the power to set safety standards for manufactured goods, but the agency attempts to set employment standards instead, a court would likely strike down the employment standards as ultra vires. The agency has exceeded the bounds of its delegated authority. Procedural Fairness In addition to ensuring that governmental bodies stay within their authority, judicial review also enforces procedural fairness. This principle requires that administrative decisions—even decisions that might be within an agency's power—must be made fairly, with proper notice and opportunity to be heard. An agency might have the power to deny a license, for instance, but it must follow fair procedures in doing so. If procedures were fundamentally unfair, a court can invalidate the decision regardless of whether the agency had power to make it. Types of Judicial Review: What Can Be Challenged? Judicial review can extend to different types of governmental action, and understanding these distinctions is essential. Administrative Acts and Secondary Legislation Most judicial review activity focuses on administrative acts—specific decisions made by executive agencies or officials. An agency denies a permit application; an inspector issues a citation; a benefit is denied. These individual decisions can be challenged through judicial review. Additionally, courts review secondary legislation (also called "delegated legislation"), which consists of general rules issued by administrative bodies pursuant to power delegated by the legislature. For example, a health agency might issue regulations about food safety. These regulations have the force of law but originate from the executive branch rather than the legislature. Courts regularly review secondary legislation to ensure it complies with the authorizing statute and the constitution. Preliminary Conditions Before filing a judicial review action, a party typically must satisfy preliminary conditions. Often, the party must first file a complaint with the responsible agency itself and exhaust administrative remedies. Only after attempting to resolve the matter administratively can the party appeal to courts. Some systems also impose strict time limits for filing judicial review, recognizing that settled expectations need protection. These procedural requirements screen out frivolous challenges and allow agencies an opportunity to correct their own mistakes before court involvement. Review of Primary Legislation The most consequential form of judicial review involves reviewing primary legislation—statutes passed by elected legislatures. Here, the stakes are highest because legislatures possess broad democratic legitimacy. However, review of primary legislation raises the question: Should courts ever be able to strike down laws enacted by representatives of the people? Different countries answer this question very differently. Two Approaches to Reviewing Primary Legislation The Parliamentary Sovereignty Approach: No Judicial Review of Statutes In the United Kingdom, courts traditionally cannot invalidate Acts of Parliament, the primary legislation passed by the legislature. This reflects the doctrine of parliamentary sovereignty—the principle that Parliament is supreme and its statutes represent the will of the people as expressed through democratic process. Under this approach, if Parliament passes a statute, courts must apply it even if judges believe it is unwise or even contrary to basic principles of fairness. The remedy for unjust laws lies with the legislature (or with voters at the ballot box), not with courts. This system trusts the democratic process to correct errors in legislation. This does not mean British courts are entirely passive, however. They can review administrative actions and secondary legislation vigorously, and they can interpret statutes strictly to avoid unreasonable outcomes. But they cannot simply declare that a statute conflicts with higher law and is therefore void. The Constitutional Review Approach: General Courts Review Statutes In contrast, the United States empowers federal and state courts to review the constitutionality of statutes. When a case comes before a court and requires interpretation of a statute, courts have authority to determine whether that statute conflicts with the Constitution. If it does, the court will declare the statute unconstitutional and refuse to apply it. This power emerged from the landmark case Marbury v. Madison (1803), in which Chief Justice John Marshall established that courts possess authority to review the constitutionality of legislation. <extrainfo>Marshall's reasoning was that the Constitution is supreme law; that when legislation conflicts with the Constitution, the Constitution must prevail; and that courts, in deciding cases, must determine which law applies. Therefore, courts must have authority to assess whether legislation conflicts with constitutional requirements.</extrainfo> The American approach rests on a different premise than parliamentary sovereignty. It assumes that courts, interpreting a written constitution, are institutionally positioned to protect fundamental rights and constitutional limits even against legislative action.
