The most consequential policy decisions of the twenty-first century are increasingly made not by legislators but by judges in robes, interpreting documents written centuries ago. This is not a bug in constitutional design—it is the logical endpoint of a system that vests final interpretive authority in unelected bodies while elected ones grow ever more polarized and gridlocked.
Constitutional courts occupy a peculiar space in democratic theory. They are meant to be referees, not players—guardians of process rather than architects of substance. Yet from Karlsruhe to Washington to Brasília, these institutions have become de facto legislators on issues ranging from reproductive rights to fiscal policy to environmental regulation. The phenomenon transcends ideology; progressive courts expand rights, conservative courts contract them, but both exercise power that would have astonished the framers of most constitutions.
The mechanics of judicial supremacy
The transformation happened gradually, then suddenly. In the American model, judicial review—the power to strike down legislation as unconstitutional—was not explicitly granted but rather asserted by the Supreme Court itself in 1803. The German Constitutional Court, established after World War II, was deliberately given expansive powers to prevent democratic backsliding, and it has used them liberally. The European Court of Justice built supremacy over national law through a series of rulings that member states initially ignored, then grudgingly accepted, and now treat as gospel.
What makes constitutional courts so powerful is not just their authority to void laws but their monopoly on constitutional meaning. When a parliament passes a statute, it is making a bet about what the constitution permits. The court holds all the cards in that wager. And unlike legislatures, courts need not build coalitions, whip votes, or face voters. A bare majority of judges—often a single swing vote—can reshape national policy overnight.
The legitimacy problem
Defenders of robust judicial review argue that rights must be protected from majoritarian excess. This is the counter-majoritarian difficulty turned into a virtue: courts exist precisely to override democratic preferences when those preferences threaten fundamental liberties. The argument has force. Minorities have often found in courts the protection that legislatures denied them.
But the argument grows strained when courts venture beyond rights into policy. When Germany's Constitutional Court rules on eurozone bailouts, or when the Dutch Supreme Court orders the government to cut emissions faster, or when India's apex court micromanages air pollution in Delhi, the counter-majoritarian rationale begins to wobble. These are not cases of protecting discrete minorities from persecution; they are cases of judges substituting their policy judgments for those of elected officials on questions where reasonable people disagree.
The result is a peculiar democratic deficit. Citizens who dislike a court's ruling have no direct recourse. They cannot vote the judges out. Constitutional amendment is typically designed to be difficult, often impossibly so. The only reliable method of changing judicial direction is to wait for judges to die or retire and hope the appointing authority shares your preferences—a grim lottery that has turned judicial nominations into the bloodiest battleground in many democracies.
Our take
Constitutional courts are not going away, nor should they. The alternative—legislative supremacy unchecked by any higher law—has its own grim history. But the current trajectory, in which courts increasingly function as superlegislatures, demands more honesty about what is happening. When a court strikes down a law, it is not merely interpreting text; it is making a policy choice dressed in legal reasoning. Acknowledging this openly would not diminish judicial authority—it would force judges to defend their choices on the merits rather than hide behind the fiction of neutral interpretation. Democracy can survive powerful courts. It struggles to survive courts that pretend they are something else.
