The Maxim: 'Lex Iniusta Non Est Lex'
Defining the Principle
The assertion "An unjust law is no law at all", expressed in Latin as lex iniusta non est lex, is a fundamental principle within the philosophy of natural law.[1] This perspective posits that for a rule to possess true legitimacy and command genuine obedience, it must align with inherent principles of justice and morality. Consequently, a law that fundamentally violates these ethical standards is considered to lack the essential qualities of law itself.
Natural Law Foundation
This viewpoint is strongly associated with theorists who advocate for natural law, such as John Finnis and Lon Fuller.[1] They argue that legal systems are intrinsically linked to morality. An unjust law, by failing to serve the common good or uphold fundamental rights, fails to meet the criteria of a true law, thereby diminishing or negating the obligation to obey it.
Historical Context and Evolution
Ancient Roots
Objections to unjust laws have echoed throughout history. The Hebrew Bible, in Isaiah 10, contains a powerful denunciation of those who create oppressive decrees and deny justice to the vulnerable:
Woe to those who make unjust laws,
to those who issue oppressive decrees,
to deprive the poor of their rights
and withhold justice from the oppressed of my people.
This passage highlights an early recognition that laws should serve justice, not undermine it.
Augustine of Hippo
In the 4th century AD, Augustine of Hippo articulated a view closely aligned with the maxim. In his work De libero arbitrio voluntatis, he stated, "for I think a law that is not just, is not actually a law" (Latin: nam mihi lex esse non videtur, quae justa non fuerit).[2][3] For Augustine, the existence of evil in the world was ultimately attributed to human departure from righteous behavior, implying that laws deviating from divine justice were manifestations of this departure.
Thomas Aquinas's Framework
Thomas Aquinas, in his seminal work Summa Theologica, exhaustively examined the legitimacy and enforceability of human-made laws. He proposed that a law must meet three criteria to be considered legitimate and thus worthy of obedience:
- Purpose: The law must serve the common good.
- Author: The law must be enacted by a legitimate authority within its proper scope.
- Form: The law's burden must be distributed equitably among the populace.
Aquinas contended that laws failing these tests, particularly those that are unjust, do not bind individuals to obedience, referencing Isaiah to support the principle that resisting oppression is always lawful.[4]
Henry David Thoreau's Stance
In his influential essay Civil Disobedience, Henry David Thoreau directly challenged the moral obligation to obey unjust laws. He famously posed the question:
“Unjust laws exist: shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once?”
Thoreau's perspective underscores the individual's moral agency in confronting laws that violate conscience.
Martin Luther King Jr.'s Application
Martin Luther King Jr, in his profound Letter from Birmingham Jail, drew upon the philosophical traditions of Augustine and Aquinas to justify civil disobedience. He argued that the segregationist Jim Crow laws were inherently unjust and therefore lacked moral authority, making their defiance a righteous act.[5]
Parallel Concepts in Indian Philosophy
The Principle of 'Rta'
Within Indian philosophy, the concept of Rta offers a parallel to the Western natural law tradition. Rta represents the fundamental cosmic order, truth, and righteousness that governs the universe. Rules derived from or aligned with Rta are considered true laws, binding even upon deities. This principle establishes a moral and ontological framework that predates and supersedes human legislation, suggesting that any ordinance contrary to this universal order lacks true validity.[6]
