Lord Denning's observation, "Be you ever so high, the law is above you," captures the essence of constitutional government. Constitutions establish institutions and impose limits on their power. While governments are created to exercise authority, the constitution demands that such exercise always remain subject to law. Most constitutional questions, however complex, ultimately return to a familiar point: where does lawful authority end? The real issue is whether power has been exercised within the limits set by the Constitution.
Constitutional Foundations in Pakistan
Like other nations, Pakistan's Constitution addresses this question from multiple angles. Some provisions concern individual rights, while others govern inter-institutional relationships. Collectively, they form a simple constitutional proposition: public power must rest on legal authority. Article 4 guarantees every citizen the protection of the law and the right to be treated in accordance with the law. Article 25 builds on this foundation by ensuring equality before the law and equal protection under the law. If people in materially similar circumstances are treated differently without lawful reason, the Constitution is breached.
These guarantees shape the citizen-state relationship. Businesses invest and entrepreneurs take commercial risks assuming the law will be applied fairly and consistently. That assumption is shaken—and public faith in the legal system erodes—when governments change rules without legal authority or enforce them selectively.
Enforcement Through Judicial Review
Article 199 of the Constitution provides the mechanism for executing these guarantees. Under this provision, High Courts are empowered to ensure that public authorities act within the law. Unbeknownst to many, most citizens' experiences with the Constitution occur in everyday dealings with the state—during a tax assessment or a regulatory approval. It is in these ordinary encounters that constitutional rights either become meaningful or remain words on paper.
The enduring constitutional question is simple: by what authority does the state act? Pakistan's constitutional history offers numerous examples. Governments have at different times restricted peaceful assembly, imposed censorship, and dissolved elected assemblies on disputed constitutional grounds. These actions have repeatedly come before courts, where judges decide whether executive power was exercised in accordance with law or merely as official discretion.
Commercial Life and Constitutional Fairness
The same issue arises in commercial life. Businesses commonly rely on government policies, only to see them withdrawn or changed. They also face unexpected regulatory changes and executive actions beyond statutory authority. Governments have the power to regulate, but the Constitution requires that these powers be exercised within legal limits and transparently. However, governments cannot be expected to keep policy unchanged forever; conditions change. The real difficulty arises when citizens have already ordered their affairs in reliance on official assurances.
For example, a business may have invested considerable capital or assumed long-term obligations because it took the government at its word. The question is whether the state can later ignore expectations its own representations created. This concern lies at the heart of two internationally recognized constitutional principles: promissory estoppel and legitimate expectation. Neither doctrine prevents government from changing course, but both require public authorities to have good reason for doing so and to act fairly in the process.
Foreign Investment and Policy Stability
The issue assumes particular significance in foreign investment. Like governments elsewhere, Pakistan often announces incentives to attract overseas capital, and investors make long-term decisions based on those commitments. If incentives are later withdrawn without adequate justification, the consequences raise a fundamental question of constitutional fairness. In Pakistan's energy sector, these concerns have become especially evident. Investors rely on the expectation that government commitments and regulatory decisions will remain stable unless there is a clear legal basis for change. When agreements are revised without transparent justification, confidence in the regulatory framework weakens investor certainty and erodes public trust.
Notably, this principle extends beyond commercial matters. It equally applies to issues involving police powers or restrictions on movement or expression. The constitutional question remains the same: what legal authority justifies the exercise of that power? Arbitrary government begins where lawful authority and procedural fairness end.
Remedies and Limits
Suitable guardrails exist under the Constitution to provide remedies when public authorities step outside legal limits. Article 199 empowers High Courts to ensure that public officials perform their legal duties and exercise only powers conferred by law. Judicial review is thus the practical means for giving real meaning to the Constitution's guarantees. However, doctrines of promissory estoppel and legitimate expectation have their limits. Governments must have room to respond to changing circumstances, and courts have consistently recognized that. "Public interest" cannot become a convenient justification for walking away from earlier commitments; it is a constitutional consideration, not a licence to act without legal justification.
For most Pakistanis, encounters with the Constitution occur through ordinary dealings with the state—license applications, disputed tax demands, or regulatory approvals. Citizens are entitled to expect that public authorities will act according to law rather than private preferences. Ultimately, the real measure of Pakistan's Constitution—like any other—is whether it can endure crises. Pakistan's Constitution has survived political upheavals, constitutional breakdowns, and repeated tests. But its central promise remains unchanged: public power is never beyond judicial review. So long as that promise remains, every citizen has the right to ask a simple but enduring question: by what authority does the state act, and for what lawful purpose? The Constitution exists to ensure that those who exercise public power are always ready to answer for their actions.
