Apartheid: Legal Definition, Treaties, and Prosecution

Under international law, the legal definition of apartheid is a crime against humanity consisting of inhumane acts committed within an institutionalized regime of systematic racial oppression and domination by one racial group over another, carried out with the intent to establish or maintain that domination. The definition appears in two treaties: the 1973 International Convention on the Suppression and Punishment of the Crime of Apartheid and the Rome Statute of the International Criminal Court. Although the concept originated with South Africa’s segregation laws, the crime is written in universal terms and can apply wherever the elements are met.

The Two Elements That Distinguish Apartheid From Discrimination

The 1973 Convention defines apartheid as “inhuman acts committed for the purpose of establishing and maintaining domination by one racial group of persons over any other racial group of persons and systematically oppressing them.”¹ Article 7(2)(h) of the Rome Statute uses parallel language, describing “inhumane acts of a character similar to those referred to in paragraph 1, committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over any other racial group or groups and committed with the intention of maintaining that regime.”²

Two elements separate this crime from ordinary racial discrimination. The oppression must be institutionalized, meaning built into the laws, administrative structures, and daily operations of government. Isolated acts of bias or sporadic unrest do not qualify. And intent matters. Prosecutors must show the conduct was carried out with the specific purpose of establishing or maintaining racial domination.

The Rome Statute does not create a separate list of prohibited conduct for apartheid. The “inhumane acts” it refers to are the same ones that make up other crimes against humanity — murder, enslavement, torture, enforced disappearance, and severe deprivations of liberty. What turns those acts into apartheid is the surrounding regime and the intent behind them.

The Two Treaties That Criminalize Apartheid

The 1973 Apartheid Convention

The UN General Assembly adopted the Convention on November 30, 1973. It was the first treaty to declare apartheid a crime against humanity and impose obligations on states to prevent and punish it. Article IV requires each ratifying state to pass domestic laws criminalizing conduct that fits the treaty’s definitions and to prosecute anyone accused of the crime found on its territory, regardless of where the acts occurred or the person’s nationality.¹

Over 100 states have ratified the Convention. The United States has never signed or ratified it.³

The Rome Statute

The Rome Statute established the International Criminal Court and lists the crime of apartheid under Article 7(1)(j) as one of the acts that constitute a crime against humanity.⁴ The ICC can prosecute individuals when national courts are unwilling or unable to do so. As of 2026, 125 states are parties. The United States signed in 2000 but formally withdrew its signature in 2002, notifying the UN Secretary-General that it did not intend to become a party and had no legal obligations under the treaty.⁵

The two instruments work together. The 1973 Convention obligates states to criminalize apartheid in their own laws. The Rome Statute gives an international court direct authority to prosecute individuals.

Acts That Qualify as the Crime

Article II of the 1973 Convention identifies specific categories of conduct that count as the crime of apartheid when carried out to maintain racial domination:

Violence against life and liberty, including killing members of a racial group, inflicting serious physical or psychological harm, arbitrary arrest, and illegal imprisonment.¹
Deliberately imposed living conditions calculated to cause the physical destruction of a racial group, in whole or in part.
Legislative measures that block a racial group from participating in political, social, economic, or cultural life, including denial of the right to work, to vote, to education, to freedom of movement, and to leave or return to one’s country.
Forced segregation, including separate residential zones or ghettos that isolate a racial group, along with bans on interracial marriage.
Economic exploitation such as forced labor, restriction of employment, and seizure of land or property to benefit the dominant group.¹

None of these acts standing alone amounts to apartheid. A single unjust arrest or one discriminatory statute is not enough. The crime requires a pattern of these acts operating together as part of an organized regime designed to keep one racial group in permanent subordination.

Who Can Be Held Criminally Responsible

Article III of the 1973 Convention establishes that criminal responsibility applies to individuals wherever they live. It reaches people who directly commit acts of apartheid, those who participate in or conspire in their commission, and those who encourage or provide material support to the regime.¹ Liability is not confined to heads of state or military commanders. A bureaucrat who designs the administrative machinery, a financier who bankrolls enforcement, or an official who drafts the segregation laws can each face personal responsibility.

Following orders is not a valid defense. Article 33 of the Rome Statute says obedience to a superior’s command does not relieve a person of criminal responsibility if they knew the order was unlawful or if it was manifestly unlawful. Paragraph 2 goes further: orders to commit crimes against humanity are considered manifestly unlawful as a matter of law.⁶ Because apartheid is classified as a crime against humanity, that blanket rule applies to it.

Where Prosecution Can Happen

Certain crimes are considered so grave that any country can prosecute them regardless of where they occurred or the nationality of the perpetrator. This is universal jurisdiction, and it applies to crimes against humanity, including apartheid. The 1973 Convention builds the principle directly into its framework: Article IV requires member states to prosecute anyone accused of apartheid found on their territory, even if the acts happened in a different country and the person is a citizen of a third state.¹

The practical effect is that there is no safe harbor. A former official who orchestrated apartheid policies cannot relocate to a treaty member state and expect to be left alone. If that country has implemented the Convention into domestic law, its courts have both the authority and the obligation to act. The ICC serves as a backstop when national courts are unable or unwilling to prosecute, but the primary burden sits with national systems.

Limits in United States Courts

Because the United States has not ratified either treaty, no federal statute specifically criminalizes apartheid. The Crimes Against Humanity Act was introduced in Congress in 2010 but was never enacted. U.S. courts are not entirely closed to apartheid-related civil claims, however. The Alien Tort Statute, dating to 1789, gives federal district courts jurisdiction over civil suits filed by non-U.S. citizens for torts committed “in violation of the law of nations.”⁷

That door has narrowed. In 2013, the Supreme Court held in Kiobel v. Royal Dutch Petroleum Co. that the statute carries a presumption against extraterritorial application, and claims must “touch and concern the territory of the United States” with sufficient force to overcome it.⁸ In 2018, Jesner v. Arab Bank, PLC ruled that foreign corporations cannot be defendants in Alien Tort Statute suits at all.⁹ The combined effect is that the statute remains a theoretical avenue for apartheid-related civil claims, but the practical hurdles are steep, and cases involving conduct that occurred entirely overseas with no strong U.S. connection are unlikely to survive a motion to dismiss.

How the Definition Has Been Applied Beyond South Africa

The definition was forged in response to South Africa but written in universal terms. In July 2024, the International Court of Justice issued an advisory opinion finding Israel responsible for apartheid in the Occupied Palestinian Territory, the first time that tribunal applied the label outside the South African context. The opinion drew on Israel’s 57-year occupation and its systems of settlement, residency restrictions, and differential legal treatment of Palestinians. Whether the finding leads to concrete enforcement action remains to be seen, since ICJ advisory opinions are not binding in the way judgments between disputing states are.

There is also growing discussion about extending the framework beyond race. Advocates have pushed for international recognition of “gender apartheid” to describe regimes that systematically exclude women from public life through legal and institutional means. No treaty or customary international law currently recognizes gender apartheid as a distinct crime. Under existing law, such conduct would most likely be prosecuted as the crime against humanity of persecution on gender grounds under Article 7(1)(h) of the Rome Statute.⁴
