How an ancient legal principle, Israel’s experience, Ukraine’s search for justice, and the preservation of living heritage point toward the next chapter of international law.

Justice is measured not only by its ability to punish wrongdoing, but by its courage to repair it.

— Rabbi Mikhail Salita

The Birth of Restitution

International law is often associated with war, diplomacy, treaties, and state sovereignty. Yet one of its most enduring principles did not begin in a battlefield or at a peace conference. It was born more than two thousand years ago in Roman law, and its influence continues to shape the modern international legal order.

That principle is restitutio in integrum.

Although the Latin phrase may sound technical, its meaning is remarkably simple. Whenever possible, justice should restore the situation that existed before a wrongful act occurred. The objective is not merely to recognize that harm has been done, nor simply to punish the wrongdoer. The highest aspiration of law is to repair the wrong itself.

This idea survived the fall of the Roman Empire, influenced European legal thought for centuries, and eventually became one of the cornerstones of modern international law. It reflects a timeless conviction: justice is incomplete if it cannot restore what has been unjustly taken away.

Modern international law has developed several mechanisms to address the consequences of internationally wrongful acts. Although these concepts are frequently used interchangeably in public discussion, each serves a distinct legal purpose.

Restitution seeks to restore the original situation by returning what has been unlawfully taken or reversing the consequences of an illegal act whenever that remains possible.

Compensation applies when restitution cannot fully repair the damage. Instead of restoring the original situation, it provides financial or material payment for losses that can no longer be reversed.

Satisfaction addresses injuries that cannot be measured in monetary terms. It may take the form of an official apology, acknowledgment of wrongdoing, or other symbolic acts that reaffirm the dignity of those who suffered.

Together, these remedies form what international lawyers broadly describe as reparation—the legal obligation to remedy the consequences of an internationally wrongful act.

Among these remedies, however, restitution occupies a unique place.

Compensation accepts that something has been lost.

Restitution refuses to accept that loss as the final outcome whenever restoration remains possible.

This distinction became one of the defining principles of modern international law in 1928, when the Permanent Court of International Justice decided the landmark Factory at Chorzów case. The Court stated that the essential consequence of an internationally wrongful act is the obligation to eliminate its consequences and restore the situation that would likely have existed had the wrongful act never occurred. Nearly a century later, this principle continues to serve as one of the intellectual foundations of state responsibility under international law.

Yet restitution is more than a legal doctrine.

It expresses a moral vision of what law is meant to accomplish.

Law should not exist merely to identify injustice. It should strive, whenever possible, to repair it.

Few examples demonstrate this principle more profoundly than the post-Holocaust relationship between Germany and Israel.

No legal agreement could restore the millions of lives destroyed during the Holocaust. No financial payment could erase suffering or undo humanity’s greatest crimes. History itself could never be reversed.

Yet Germany’s willingness to accept legal responsibility and Israel’s willingness to transform that acknowledgment into a framework for rebuilding demonstrated something extraordinary. Restitution and reparative justice became more than legal mechanisms. They became........
