Constitutional Revision and Why Most Governments Fear It

A constitution is a form of institutional technology — a designed solution to problems of governance. Like all technologies, it embeds the knowledge, values, and constraints of its moment of creation. Unlike most technologies, it is extremely difficult to update. We do not use the medical treatments or the agricultural practices of the founding era. We update our software, our infrastructure, our legal codes, our scientific models. But in many countries, the foundational document of governance has changed remarkably little since its original ratification, often more than a century ago, despite transformations in technology, demography, economy, and moral understanding so fundamental as to be nearly incomprehensible to the original drafters.

The American Constitution, ratified in 1788 and amended fundamentally in the immediate aftermath of the Civil War, governs a country of 330 million people spread across a continental empire, with a digital economy, a professional standing military, nuclear weapons, and telecommunications infrastructure of a kind the framers could not have imagined. It does so through a text that contains 7,591 words and has been formally amended 27 times, the most recent amendment ratified in 1992, the majority of them added within the first few years after ratification or immediately after the Civil War.

This is not a critique of the American constitutional tradition — it is a description of a common pattern in long-running constitutional orders. The text persists. The world it governs changes. The gap is managed through interpretation, convention, and informal adaptation. But the gap itself is rarely acknowledged as a problem deserving formal attention.

The resistance to constitutional revision is overdetermined — there are multiple overlapping reasons, each reinforcing the others.

Incumbent advantage. Existing constitutional arrangements produced the current distribution of power. Those in power under the current constitutional structure have generally done well by it. Constitutional revision might alter those arrangements — redistributing power between branches, between levels of government, between electoral constituencies, between demographic groups. Even if the redistribution would be more just or more functional, those who would lose advantage have strong incentives to oppose it and to dress their opposition in principled language about the sanctity of foundations.

Legitimacy anxiety. Constitutional revision triggers a kind of political vertigo because constitutions serve a legitimating function beyond their specific provisions. They are the source from which government authority derives. If the constitution can be revised, what governs the revision process? The answer — the amendment procedures specified in the constitution itself, or in some cases a parallel constituent process — is logically coherent but psychologically unsatisfying. It can feel like lifting yourself by your own bootstraps. This anxiety is exploited by those who oppose revision, who characterize any proposal as an attack on the foundations of legitimate government rather than as governance of the amendment process the constitution itself provides for.

Manipulation risk. Constitutional revision processes can be captured by whoever has the power to initiate and control them. In some countries, governing parties have called constitutional assemblies specifically to entrench their own power, extend executive authority, or weaken institutional checks that had constrained them. Venezuela, Nicaragua, Bolivia, and Hungary offer recent examples of constitutional revision processes that reduced rather than expanded democratic governance. These examples are genuine — they are not invented by constitutional conservatives — and they create legitimate concern that revision processes, once opened, may be captured by actors with anti-democratic intentions.

Revision fatigue. Countries that revise their constitutions frequently are often (though not always) countries with unstable governance. France has had five republics. Many Latin American and African countries have had multiple constitutions since independence. This instability is real, though the causal relationship is contested — does frequent constitutional revision cause instability, or does instability cause frequent constitutional revision? The association, real or perceived, creates a heuristic that constitutional stability is good and constitutional revision is dangerous, which is used to resist revisions that would be desirable on the merits.

Coalition complexity. In federal systems and systems with supermajority requirements, constitutional revision requires assembling coalitions far larger than those needed for ordinary legislation. Every veto player — every actor with the power to block the amendment — has to agree. This gives any faction a potential blocking position, and factions can use that blocking position to demand concessions or simply to ensure that revision cannot occur. The more veto players a system has, the higher the effective cost of constitutional change — and the more the current distribution of power, embedded in constitutional structure, is protected from revision.

When constitutional amendment is effectively impossible, several predictable pathologies develop.

Judicial overreach as workaround. Courts are asked to do work that requires constitutional amendment but which cannot be achieved through amendment. The result is constitutional interpretation that strains the text past any reasonable reading, producing doctrines of contested legitimacy and triggering political backlash. The history of the American Supreme Court is substantially a history of the Court trying to update constitutional meaning for an evolving society while lacking the text to do so cleanly, producing decisions that satisfy no one and trigger decades of political conflict that formal amendment might have resolved more cleanly.

Constitutional deadlock. Structural features that should be revised — the relationship between institutions, the distribution of powers, the electoral rules — cannot be changed because the coalition required for amendment cannot be assembled. These structural features then produce governance dysfunction that affects millions of people and cannot be addressed through ordinary legislation. The dysfunction accumulates until a crisis point at which revision becomes not merely desirable but urgent, and urgent constitutional revision, conducted under political crisis with all factions maximally mobilized, is among the worst conditions for getting revision right.

Informal constitutional change. The formal constitution stays fixed while informal constitutional change accumulates through convention, precedent, executive practice, and legislative accommodation. This informal change is less transparent, less democratically legitimate, and harder to reverse than formal amendment. The "unwritten constitution" of conventions and practices that builds up around a fixed text often diverges substantially from the text in ways that are invisible to ordinary citizens and accountable to no one.

Fossilization of historical injustice. Constitutional provisions that entrench historical arrangements — arrangements that favored particular groups, that encoded practices now understood as unjust, that locked in geographies of political power reflecting a historical moment that has passed — become nearly impossible to revise. The Senate representation of small versus large American states, the Electoral College, the specific procedures for presidential succession — these features were designed for a country that looked very different from the current one, and arguments for their revision consistently collide with the impossibility of assembling the required coalition.

Constitutional revision is not inherently destabilizing. Several countries have managed it with positive results.

Germany's Basic Law of 1949, designed explicitly to correct the constitutional failures that enabled Hitler's rise, has been amended more than 60 times since its enactment. The amendment process — requiring a two-thirds majority in both legislative chambers — is demanding but not impossibly so, and the Basic Law has been updated to address German reunification, European integration, new understandings of rights, and changes in governmental structure. German constitutional stability over the past seven decades is not threatened by this revision history; it has been enabled by it.

The Nordic countries — Denmark, Finland, Norway, Sweden — have maintained constitutional frameworks that have been periodically revised to address new circumstances while maintaining robust democratic governance. Sweden's constitution, for instance, underwent a comprehensive revision in 1974 that modernized the governmental structure, and has been amended multiple times since. Constitutional revision is not treated as a crisis but as governance.

South Africa's post-apartheid constitution of 1996 is widely regarded as one of the most sophisticated foundational documents in the world. It has been amended seventeen times since adoption, and the amendment process has been used to address issues that arose in implementation. The constitution's legitimacy rests not on its immutability but on the breadth of the deliberative process that produced it and the ongoing democratic accountability of those who interpret and apply it.

The alternative to constitutional sclerosis is not constant revision or instability — it is a political culture that treats constitutional maintenance as an ongoing responsibility rather than a settled matter. This culture has several features.

It includes periodic review mechanisms: formal processes for examining whether constitutional provisions are still serving their intended purpose, conducted at regular intervals, by bodies with appropriate legitimacy and broad composition. Ireland's constitutional conventions and Citizens' Assemblies offer a partial model — deliberative bodies composed of randomly selected citizens, engaging with constitutional questions and making recommendations to the legislature and through referendum to the electorate.

It includes educational investment in constitutional literacy — widespread public understanding of what the constitution says, what the amendment process is, why specific provisions exist, and what the arguments for and against specific revisions are. Constitutional revision is only possible in a democracy where citizens can engage with the substance of proposed changes, and that requires a baseline of constitutional knowledge that most democratic systems do not invest in producing.

It includes a political norm that treats constitutional discussion — including critical discussion and proposals for revision — as legitimate democratic activity rather than as attack on the foundations of order. The conflation of constitutional criticism with constitutional bad faith is itself a political move, and recognizing it as such is a precondition for honest public conversation about constitutional design.

A constitution is not sacred. It is a governance document, produced by human beings, embedding their best thinking about foundational design under specific historical circumstances. Like all such documents, it deserves both respect for what it has achieved and honest assessment of where it has fallen short or been outrun by circumstances. Treating revision as a civic responsibility rather than a civic threat is one of the marks of a civilization capable of governing itself intelligently over time.
