The World Trade Organisation (WTO) — Public International Law Notes

The World Trade Organisation (WTO)

For nearly fifty years, world trade ran on a provisional deal — the GATT of 1947 — with no real institution and no teeth. Then, on 1 January 1995, the World Trade Organisation opened its doors in Geneva, built by the Marrakesh Agreement of 1994. Its one revolutionary feature is this: it has a binding, compulsory dispute-settlement system. It is the single place in all of international law where a State can be hauled before a tribunal without giving fresh consent, and where — if it still refuses to comply — retaliation is lawfully authorised. That mechanism is what the examiner asks about most.

What the WTO is, its principles, structure, functions and dispute settlement

The World Trade Organisation (WTO) is the international organisation that administers the rules of trade between nations. It was established on 1 January 1995 by the Marrakesh Agreement (1994), the outcome of the Uruguay Round, as the successor to the GATT (General Agreement on Tariffs and Trade, 1947); its headquarters are in Geneva. Learn it in four parts: principles, structure, functions, and dispute settlement.

A. Main features / guiding principles

Non-discrimination, in two forms:
- Most-Favoured-Nation (MFN) treatment — a trade advantage granted by a member to one country must be extended immediately and unconditionally to all members: treat every trading partner alike.
- National treatment — imported goods, once they have entered a market, must be treated no less favourably than domestic goods: do not discriminate between foreign and local products.
Freer trade through negotiated, progressive reduction of tariffs and barriers, and binding of tariff ceilings.
Predictability and transparency — commitments are bound and trade rules are published.
A single institutional framework binding on all members (unlike the fragmented GATT “à la carte” system).

B. Structure

The Ministerial Conference — the top organ; all members; meets at least once every two years; may take decisions on all matters (Art. IV of the Marrakesh Agreement).
The General Council — all members; runs the WTO between Ministerial Conferences; also convenes as the Dispute Settlement Body (DSB) and the Trade Policy Review Body.
Subordinate councils — the Council for Trade in Goods, the Council for Trade in Services, and the Council for TRIPS (trade-related intellectual property).
The Secretariat, headed by a Director-General, based in Geneva.

C. Functions

Administering the WTO trade agreements; providing a forum for trade negotiations; handling trade disputes; reviewing members’ national trade policies; assisting developing countries; and co-operating with the IMF and the World Bank on global economic policy.

D. Dispute settlement — the distinguishing feature

Governed by the Dispute Settlement Understanding (DSU), run by the Dispute Settlement Body (DSB). The stages:

Consultation — the disputing members must first try to settle by negotiation.
Panel — if that fails, the DSB establishes a panel of experts, which hears the dispute and reports.
Appellate Body — either side may appeal the panel’s legal findings to a standing Appellate Body.
Adoption by “negative (reverse) consensus” — the panel/Appellate report is adopted by the DSB unless there is a consensus to reject it. Because the winning party will never join such a consensus, adoption is practically automatic — this is what makes the system compulsory and binding.
Implementation and retaliation — the losing member must comply; if it does not, the DSB may authorise the complaining member to suspend concessions (retaliation) against it.

🔑 The negative-consensus rule is the whole trick. Under the old GATT a losing State could block adoption of the report against it; under the WTO a report is adopted unless everyone (including the winner) agrees to throw it out. That reversal turned a toothless procedure into the only truly compulsory, binding dispute system in international law.

Article II(1), Marrakesh Agreement Establishing the WTO (1994): “The WTO shall provide the common institutional framework for the conduct of trade relations among its Members in matters related to the agreements and associated legal instruments included in the Annexes to this Agreement.”

In Simple Terms: The WTO (born 1995, in Geneva, replacing the 1947 GATT) is the referee of world trade. Its golden rules are non-discrimination — treat all trading partners alike (MFN) and treat foreign goods like local ones (national treatment) — plus lower, predictable tariffs. It is run by a Ministerial Conference over a General Council and specialised councils. Its crown jewel is dispute settlement: consult, then a panel, then an Appellate Body, and the ruling is adopted almost automatically (negative consensus) and binds — if the loser won’t comply, retaliation is authorised.

🧩 WORKED EXAMPLE — the loser tries to block the ruling

Facts. A WTO panel, upheld on appeal, finds that State M’s import ban on State N’s goods breaches WTO rules. M announces it will “block adoption” of the report in the DSB, as it could have done under the old GATT.

Rule. Under the DSU, a panel/Appellate Body report is adopted by the DSB by negative (reverse) consensus — it stands unless all members, including the winning party, agree to reject it.

Apply. The decoy is M’s memory of GATT practice, where a single objecting State could veto adoption. That is gone: N (the winner) will never consent to reject a ruling in its favour, so the required consensus to block can never form. The report is adopted.

Conclusion. M cannot block the ruling; it must comply, or N may seek DSB authorisation to retaliate by suspending trade concessions. This automatic, binding quality is the WTO system’s defining feature.

Case Laws

United States — Standards for Reformulated and Conventional Gasoline (1996, WTO Appellate Body) — the first Appellate Body report; WTO agreements are not to be read “in clinical isolation from public international law”, and the environmental exception was misapplied here.
European Communities — Regime for the Importation, Sale and Distribution of Bananas (1997, WTO Appellate Body) — a leading application of the MFN and non-discrimination disciplines, and of the binding dispute-settlement and retaliation machinery.
