Sample ENA Section Diplomatie Practice Questions

Try these sample questions to review concepts for the ENA Section Diplomatie exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 25+ question experience with AI tutoring.

1Under the ICJ Statute, which is a subsidiary means for determining rules of international law?

A.Treaty rules accepted by the parties

B.International custom accepted as law

C.Judicial decisions and qualified scholarly teachings

D.General principles of law

Explanation: The Statute distinguishes judicial decisions and scholarly teachings as subsidiary means of identifying law. They assist the determination of rules rather than occupying the same category as conventions, custom and general principles.

2Which combination is required to identify customary international law?

A.Repeated conduct and acceptance of that practice as law

B.Repeated conduct and commercial convenience alone

C.A treaty signature without examining practice or legal acceptance

D.A General Assembly majority without examining practice or legal acceptance

Explanation: The ILC's conclusions require a general practice accepted as law, commonly called opinio juris. Frequent behaviour alone may reflect courtesy or convenience rather than a legal obligation.

3Which officials represent their State for all acts relating to treaty conclusion without producing full powers under the Vienna Convention on the Law of Treaties?

A.All diplomatic mission staff

B.All parliamentary committee chairs

C.All accredited conference delegates

D.Heads of State, Heads of Government and Ministers for Foreign Affairs

Explanation: The Convention recognizes these three offices as possessing representative capacity by virtue of their functions. Other representatives may have narrower authority or require appropriate full powers.

4A State accepts that its consent to a treaty was valid, but later enacts a conflicting domestic statute. Which analysis correctly separates performance from validity of consent?

A.The later statute automatically terminates the treaty

B.Internal law does not justify non-performance; the Convention's separate rules on invalid consent are not triggered merely by a later conflict

C.The treaty remains binding only if the other parties amend their domestic law

D.Domestic legislation unilaterally modifies the treaty for every party

Explanation: The Vienna Convention does not permit internal law to justify failure to perform a treaty. Its narrow rule concerning manifest violations of fundamental internal rules on competence to conclude treaties concerns consent, not every subsequent legislative conflict.

5Treaty A conflicts with an existing jus cogens norm when concluded. Treaty B was validly concluded, but later conflicts with a newly emerging jus cogens norm. Which analysis correctly distinguishes the two situations under the Vienna Convention?

A.Both treaties remain valid if their parties consent to the conflict

B.Treaty A is void from conclusion; Treaty B becomes void and terminates when the new peremptory norm emerges

C.Both treaties were necessarily void from their original conclusion

D.Treaty A merely suspends performance; Treaty B remains binding until its parties unanimously agree otherwise

Explanation: The Convention distinguishes conflict with a peremptory norm at conclusion from emergence of a new peremptory norm later. The former makes the treaty void at conclusion, while the latter makes an existing conflicting treaty void and terminates it; party consent does not authorize derogation.

6A treaty does not prohibit reservations or restrict them to a specified list. What further test governs a proposed reservation under the Vienna Convention?

A.Compatibility with the treaty's object and purpose

B.Whether the reservation lowers the State's implementation costs

C.Approval by the State's embassy alone

D.Whether the reservation was drafted after the treaty entered into force for every party

Explanation: The Convention prohibits reservations incompatible with the treaty's object and purpose. Absence of an express prohibition therefore does not make every reservation permissible.

7Which approach follows the Vienna Convention's general rule of treaty interpretation?

A.Use only the negotiator's unpublished personal intentions

B.Always choose the interpretation most favourable to the stronger State

C.Read isolated words without the surrounding provisions

D.Interpret in good faith using ordinary meaning in context and in light of object and purpose

Explanation: The general rule combines text, context, object and purpose within good-faith interpretation. Preparatory work has a supplementary role under the Convention rather than automatically replacing that rule.

8A treaty's performance requires an indispensable physical object. It disappears permanently, but the disappearance results from the invoking State's own breach of an international obligation owed to another treaty party. Can that State rely on supervening impossibility under the Vienna Convention?

A.Yes, permanent disappearance overrides every other condition

B.No, the Convention excludes reliance where the impossibility results from the invoking party's specified breach

C.Yes, because the own-breach limitation applies only to domestic obligations

D.No, because impossibility can never be a treaty-termination ground even without the party's breach

Explanation: Permanent disappearance of an indispensable object can satisfy the material element of impossibility. The Convention separately prevents a party from invoking this ground when the impossibility results from its own breach of the treaty or another international obligation owed to another treaty party.

9What is agrément in appointing a head of diplomatic mission?

A.The sending State's internal promotion decision

B.The receiving State's agreement to the proposed person

C.The final signature of a trade treaty

D.The consular authorization called an exequatur

Explanation: The sending State must ascertain that the receiving State has given agrément for its proposed head of mission. The receiving State is not obliged to explain a refusal.

10Under the Vienna Convention on Diplomatic Relations, must a receiving State explain why it declares a diplomat persona non grata?

A.Yes, and obtain the sending State's consent

B.Yes, but only after a criminal conviction

C.No; the Convention permits notification without explaining the decision

D.No, but it must first terminate all diplomatic relations

Explanation: A receiving State may notify the sending State that a diplomat is persona non grata without explaining its decision. This mechanism does not require a conviction or termination of relations.
