Public International Law

Ten examinable topics for the second-year SOAS PIL exam, written in the IRAC structure (Issue → Rule → Application → Conclusion) the course convenor expects, with the leading cases (Nicaragua, Lotus, North Sea Continental Shelf, Pinochet, Germany v Italy, Wall Advisory Opinion, Armed Activities, Oil Platforms), the codifying instruments (VCLT 1969, Montevideo Convention 1933, ILC Articles on State Responsibility 2001, UN Charter), and the theorists you should engage with (Crawford, Brownlie, Koskenniemi, Anghie, Chimni, Mutua, Kattan, Higgins, Charlesworth).

How the exam works

Format: open book; 2 hours; one question (or one of two parts) from the set paper.

Structure: each question is a quotation or proposition followed by “discuss”. The lecturer rewards a clear thesis sustained from introduction to conclusion, not the historical/political windup.

What examiners reward (Drew, exam tips): use the IRAC formulaIdentify the legal issue, set out the Rule or framework, Apply it, Conclude. Always give legal authority for every proposition (case + date, treaty article number). Do not just describe the law — engage with it, deploy it, build an argument with it. Set out both sides and critique the position you oppose. Have your own voice.

What loses marks: long political/historical introductions, footnotes, unsupported assertions, polemical or judgmental language, citing “the Montevideo Convention” instead of “Article 1 of the Montevideo Convention 1933”, sitting on the fence. The law is the tool; your argument is the work.

The ten topics below map to the lecture series and tutorials. The strategy card at the bottom distils Drew’s exam-tips handout, the IRAC formula and the theorists you can lift directly into a script.

01

What is International Law?

Definition, sources, the “is it really law?” question (Austin, Hart, Koskenniemi). The decentralised system: no legislature, no compulsory court, no police force. Sovereignty, consent, the Lotus presumption.

Exam Strategy & Theoretical Foundations

Drew’s IRAC formula spelt out, the “dos and don’ts” from her tips handout, time management for an open-book 2-hour paper, citation conventions, common pitfalls, and the cross-cutting theorists (Crawford on statehood, Koskenniemi’s apology/utopia, Chimni’s TWAIL, Higgins on the policy-process tradition, Charlesworth on feminist method).
