Sao Paulo, Brazil - September 18, 2026 - In an era defined by rapid technological change, global economic integration and increasingly complex relationships between individuals, businesses and governments, one principle remains fundamental: people need to know the rules under which they are expected to operate.
Legal certainty is often discussed as an abstract legal concept. In practice, however, it has very tangible consequences. Individuals make decisions about their property, careers and families based on existing rules. Businesses enter into contracts, invest capital and plan for the future based on the expectation that laws will be understandable, institutions will function consistently and legal rights will be respected.
For Brazilian attorney and Italian-Brazilian citizen Helio Pagliari Lupifieri, this predictability is one of the foundations of confidence in any legal system.
Institutions Matter as Much as Laws
A sophisticated legal system is not defined solely by the number of laws it produces. The effectiveness of those laws also depends on the institutions responsible for interpreting and applying them.
Courts, legislatures, administrative authorities and other public institutions each perform different functions, but their credibility ultimately depends on principles such as transparency, consistency, accountability and respect for established legal processes.
"The law must do more than establish rights and obligations. It must provide people with a reasonable degree of certainty about how those rights and obligations will be interpreted and protected over time," Lupifieri said.
The concept is recognized across different legal traditions. The European Commission, for example, identifies legal certainty, separation of powers, equality before the law, effective judicial protection and safeguards against arbitrary executive power among the core principles associated with the rule of law.
"Strong institutions are not those that never change," Lupifieri added. "They are institutions capable of adapting while preserving the principles that allow citizens and businesses to trust the legal system."
Predictability Does Not Mean Resistance to Change
Legal certainty should not be confused with keeping laws permanently unchanged. Modern societies require legislation to evolve. New technologies create questions that legislators could not have anticipated decades ago. Economic relationships cross national borders with increasing frequency. Artificial intelligence, digital assets, data protection and new forms of commerce continue to challenge traditional legal frameworks.
The challenge is therefore not to prevent change, but to ensure that change takes place through transparent and understandable processes.
A Question That Extends Beyond Borders
As relationships increasingly extend across national boundaries, legal certainty becomes even more important. Europe and South America, for example, represent distinct legal traditions, constitutional structures and regulatory environments. Yet individuals and businesses interacting across these regions often share a basic expectation: that agreements will be respected, procedures will be understandable and institutions will provide mechanisms for resolving disputes.
As a Brazilian attorney and Italian-Brazilian citizen, Lupifieri sees firsthand how international connections, whether personal, academic, professional or business-related, make institutional credibility a shared interest that transcends borders.
The Rule of Law as a Long-Term Asset
The strength of a legal system is measured not only by the rights written into its laws, but by the confidence people have that those rights will continue to mean something tomorrow.
"When legal certainty and strong institutions work together, we create real opportunities for people, businesses and societies," Lupifieri concluded.
