Principle of Non-Refoulement

The obligation not to return refugees or asylum seekers to a country where they face serious harm or persecution.

Updated April 23, 2026


How It Works in Practice

The Principle of Non-Refoulement operates as a fundamental safeguard in international law to protect refugees and asylum seekers from being forcibly returned to countries where their lives or freedoms could be threatened. When an individual applies for asylum, authorities must assess whether sending them back would expose them to persecution, torture, or other serious harm. If such risks are identified, the state is legally obligated to provide protection rather than expel or deport the person.

This principle is embedded in key legal instruments such as the 1951 Refugee Convention and its 1967 Protocol, as well as in customary international law, meaning it binds all states regardless of treaty ratification. Non-refoulement applies not only at borders but also within a state's territory, preventing indirect return through third countries that may present similar dangers.

Why It Matters

Non-refoulement is crucial because it preserves human dignity and prevents grave violations of human rights. Without this principle, vulnerable people fleeing war, political oppression, or persecution could be sent back to face imprisonment, torture, or death. It helps maintain international humanitarian standards and fosters global cooperation in refugee protection.

Additionally, non-refoulement supports international peace and security by encouraging states to share responsibility for refugees rather than forcing them into dangerous situations. It also reinforces the rule of law by limiting arbitrary state actions against displaced persons.

Principle of Non-Refoulement vs Expulsion

While non-refoulement prohibits returning individuals to harm, expulsion is a state's right to remove non-citizens from its territory under certain conditions, such as criminal activity or threats to public order. The key difference is that expulsion must not violate non-refoulement obligations; a state cannot expel someone if doing so would expose them to serious harm.

This distinction ensures that states maintain control over their borders while upholding international legal protections for refugees and asylum seekers.

Real-World Examples

One prominent example is the European Court of Human Rights ruling against the United Kingdom in the case of Soering v. United Kingdom (1989). The Court held that extraditing a person to the United States where they faced the death penalty under conditions of inhumane treatment violated the prohibition of refoulement.

Another case involves Australia’s policy of offshore processing, where concerns have been raised about whether asylum seekers are effectively being refouled by being sent to countries with inadequate protection.

Common Misconceptions

A common misconception is that non-refoulement offers absolute protection to all migrants, but in reality, it specifically protects those who qualify as refugees or face serious threats. Economic migrants or individuals not at risk of persecution may be lawfully returned.

Another misunderstanding is that non-refoulement prevents any form of removal. However, the principle allows for lawful deportation or expulsion if the individual’s safety is not at risk.

Finally, some believe that non-refoulement only applies to states that have signed the Refugee Convention; in fact, it is considered a rule of customary international law binding on all states.

Example

In 1989, the European Court of Human Rights ruled that the UK could not extradite a suspect to the US due to the risk of inhumane treatment, illustrating non-refoulement in action.
