Why the Rule of Law Matters for Investment, Sustainability, and Democratic Stability

In Sobre el Imperio de la Ley, Javier Cremades García reminds us of a principle essential to every constitutional democracy: legitimate authority is not authority without limits. Electoral mandates confer political power, but constitutional systems require that such power remain subject to institutional checks, judicial independence, and the rule of law.

The book invites readers to understand the rule of law not as a legal abstraction, but as a civic responsibility and a foundational element of institutional legitimacy. Cremades revisits several of its essential pillars: constitutionalism, democracy, separation of powers, the primacy of fundamental rights, and civilian supremacy over military power.

The strength of democratic institutions does not depend solely on the existence of formal legal structures. It also depends on the presence of an informed, vigilant, and engaged civil society capable of defending constitutional principles developed through centuries of political philosophy, constitutional practice, civic struggle, and institutional evolution. These principles are not obstacles to development. On the contrary, they help build societies that are more trustworthy, productive, stable, and resilient.

When rights are protected and institutions remain credible, public trust strengthens. Where trust exists, individuals and businesses invest, cooperate, innovate, participate, and demand accountability. The World Bank and other international institutions have repeatedly linked justice systems and the rule of law to poverty reduction, economic growth, social stability, security, and long-term prosperity.

Institutional Stability and Economic Development

One of the book’s most compelling themes is the relationship between institutional strength and long-term development.

Stable constitutional systems create predictability. Predictability encourages investment. Investment supports infrastructure, entrepreneurship, innovation, and economic growth. By contrast, institutional uncertainty increases risk premiums, weakens confidence, and undermines long-term planning.

For internationally connected businesses and investors, legal certainty is not an abstract academic concern. It directly affects capital allocation, infrastructure development, financing structures, regulatory strategy, and commercial decision-making.

The rule of law therefore serves not only democratic legitimacy, but also economic competitiveness.

Cremades illustrates these tensions through examples drawn from several jurisdictions. In Mexico, the book references constitutional and legal developments that have generated debate regarding institutional balance, including the reform to the Electricity Industry Law, the so-called “Zaldívar Law,” the 2024 judicial reform, and the constitutional supremacy reform.

The broader concern is not whether constitutions may be amended — constitutional systems necessarily evolve over time. The concern arises when reforms weaken institutional counterweights, diminish judicial independence, or reduce meaningful mechanisms of constitutional review. Democracies depend not only on electoral legitimacy, but also on the preservation of institutions capable of limiting arbitrary power.

These reflections are not limited to any single country. Similar debates continue to emerge across consolidated democracies, including the United States and parts of Europe, where discussions surrounding executive authority, institutional trust, political polarization, and judicial independence increasingly shape public discourse.

As King Charles III recalled before the United States Congress on April 28, constitutional traditions have long recognized that executive power must remain subject to checks and balances. The Constitution does not exist to obstruct democracy, but to preserve democratic legitimacy from its potential distortions.

Sustainability, Energy Transition, and Governance

From the perspective of international business, renewable energy, infrastructure, and sustainability, the rule of law is not separate from development policy — it is one of its foundations.

Effective climate action, energy security, infrastructure development, and industrial transition all depend on legal certainty, institutional trust, civic participation, and respect for fundamental rights.

Large-scale infrastructure and sustainability initiatives require long investment horizons, regulatory continuity, transparent institutions, enforceable contracts, and credible dispute resolution mechanisms. Without institutional confidence, even well-designed policy objectives become difficult to implement.

The energy transition, in particular, requires an integrated approach that balances climate objectives with economic development, regulatory predictability, social participation, and long-term institutional credibility.

For globally connected businesses, investors, founders, and policymakers, these issues are increasingly interconnected. Governance frameworks, constitutional stability, investment environments, and sustainability objectives now operate within the same strategic conversation.

Final Reflections

Sobre el Imperio de la Ley ultimately serves as a reminder that democratic institutions require continuous stewardship.

The rule of law is not self-executing. It depends on institutions willing to exercise restraint, independent judges capable of applying constitutional principles without political pressure, and citizens prepared to defend the legitimacy of constitutional systems even during periods of political polarization.

Strong institutions foster trust. Trust supports investment, cooperation, innovation, and long-term development. In an increasingly interconnected world shaped by cross-border markets, technological transformation, energy transition, and geopolitical uncertainty, the preservation of institutional legitimacy remains one of the defining challenges of modern democratic societies.
