An exclusionary clause is a provision that narrows the reach of a legal instrument by carving out specified categories of persons, conduct, territory, or disputes that would otherwise fall within its scope. The technique appears across international law, refugee law, human rights treaties, and private contracts.
The most cited example is Article 1F of the 1951 Refugee Convention, which excludes from refugee protection any person with respect to whom there are "serious reasons for considering" they committed a crime against peace, a war crime, a crime against humanity, a serious non-political crime outside the country of refuge, or acts contrary to the purposes and principles of the United Nations. UNHCR has issued interpretive guidelines on Article 1F, and national courts—such as the UK Supreme Court in Al-Sirri v Secretary of State for the Home Department (2012)—have refined the evidentiary threshold.
Exclusionary clauses also appear in:
- Jurisdictional instruments, where states accept compulsory jurisdiction subject to reservations. Many declarations under Article 36(2) of the ICJ Statute contain exclusions for disputes involving national security, multilateral treaties, or specified third states.
- Extradition and mutual legal assistance treaties, which typically exclude political offences, though the "political offence exception" has been narrowed by counter-terrorism conventions.
- Trade and investment agreements, where general exceptions (e.g., GATT Article XX, security exceptions in BITs) function as exclusionary provisions allowing parties to derogate for public morals, health, or essential security interests.
- Human rights treaties, which may permit derogation clauses (e.g., ICCPR Article 4) but prohibit exclusion of non-derogable rights such as the prohibition on torture.
In contract law, an exclusionary or exemption clause limits or excludes liability between parties; courts often subject such clauses to strict construction and statutory controls (for instance, the UK Unfair Contract Terms Act 1977).
For MUN delegates, exclusionary clauses matter when drafting resolutions or treaty annexes: precise carve-outs prevent overbroad obligations but, if poorly drafted, can swallow the rule.
Example
In 2017, Canadian courts applied Article 1F(a) of the Refugee Convention to exclude a former Rwandan official from refugee status based on alleged complicity in the 1994 genocide.
Frequently asked questions
A reservation is a unilateral statement by a state modifying the treaty's effect for that state, while an exclusionary clause is a provision in the treaty text itself that applies uniformly to all parties.
