The dramatic image of democratic collapse involves soldiers, seized television stations, and a general addressing the nation from behind a desk. The mundane reality is a parliamentary session, a supermajority vote, and a constitutional amendment that removes term limits or expands executive power. The coup d'état makes for better cinema; the constitutional amendment makes for more effective authoritarianism.
This pattern—using a constitution's own amendment procedures to hollow out its protections—has become the dominant mode of democratic backsliding in the twenty-first century. Hungary's Viktor Orbán didn't suspend his country's constitution; he rewrote it, legally, through the amendment process his party's supermajority controlled. Venezuela's Hugo Chávez held referendums. Turkey's Recep Tayyip Erdoğan won a constitutional vote. The paperwork was immaculate.
The paradox of constitutional flexibility
Every constitution must balance rigidity against adaptability. Too rigid, and the document becomes a straitjacket, unable to accommodate social change or correct its own errors. Too flexible, and it offers no protection against the government of the moment. The United States Constitution sits toward the rigid end—requiring two-thirds of both congressional chambers and three-fourths of state legislatures for amendment—which is why it has been amended only twenty-seven times in nearly two and a half centuries. Many newer constitutions, particularly those written in the optimistic years following the Cold War, chose flexibility. They trusted that democratic norms and political culture would constrain what legal mechanisms permitted.
That trust has proven misplaced with uncomfortable frequency. When a single party or coalition captures enough legislative seats, the amendment threshold transforms from a safeguard into a mere formality. Poland's Law and Justice party systematically altered judicial appointment procedures through ordinary legislation and constitutional interpretation, avoiding formal amendment while achieving similar ends. The technique has been called "constitutional hardball"—playing within the technical rules while violating their spirit.
The legitimacy problem
What makes constitutional amendments so effective as tools of democratic erosion is precisely what makes them so difficult to oppose: they carry the imprimatur of legality. A military coup invites international condemnation, sanctions, and domestic resistance. A constitutional amendment passed by an elected legislature invites hand-wringing op-eds and little else. The European Union spent years debating whether Hungary's changes violated democratic principles, ultimately concluding that they probably did while struggling to articulate exactly which rule had been broken.
This legitimacy extends domestically. Citizens who would take to the streets against a military takeover often accept constitutional changes with resignation or even approval. The amendment process, after all, is how democracies are supposed to evolve. Distinguishing between legitimate constitutional development and democratic self-destruction requires a sophistication about institutional design that most voters, reasonably enough, do not possess.
The unamendable amendment
Some constitutional designers have attempted to solve this problem through "eternity clauses"—provisions that declare certain principles unamendable under any circumstances. Germany's Basic Law famously protects human dignity and the democratic federal structure from amendment. Brazil's constitution shields federalism, direct elections, and separation of powers. These clauses represent a kind of constitutional pre-commitment, an attempt by one generation to bind all future generations to certain fundamental principles.
The effectiveness of eternity clauses remains contested. They work only if courts are willing to enforce them and if political actors accept judicial authority—conditions that tend to erode precisely when eternity clauses become relevant. A government determined to dismantle constitutional limits can replace judges, pack courts, or simply ignore rulings. The clause becomes a speed bump rather than a barrier.
Our take
The uncomfortable truth is that no constitutional design can fully protect against a determined majority that has lost faith in democratic constraints. Constitutions are not self-enforcing mechanisms but rather codified agreements that depend on a critical mass of political actors choosing to honor them. The amendment trap reveals this dependency with particular clarity: the same democratic legitimacy that makes constitutions meaningful also makes them vulnerable. The solution, such as it exists, lies less in clever institutional engineering than in the harder work of maintaining political cultures where winning an election is not understood as license to rewrite the rules of the game.
