Institutions and decision making:
The highest decision making body in the WTO is the ministerial conference that meets at least once in two years. So far, these conferences have been held in Singapore (1996), Geneva (1998), Seattle (1999), Doha (2001), Cancun (2003) and Hong Kong (2005).
In between the ministerial conferences, the hctions of the ministerial conference are conducted by the General Council. There are councils for specific areas: Council for Trade in Goods for the implementation of agreements on goods, Council for Trade in Services for implementation of the GATS and Council for TRIPS for implementation of the Agreement on TRIPS.
The Dispute Settlement Body (DSB) operates the DSU, as mentioned earlier. All countries in the WTO are members of all these bodies.
Decisions are generally taken in the WTO by consensus, which has been specifically defined. A decision will be deemed to be made by consensus "if no Member, present at the meeting when the decision is being taken, formally objects to the proposed decision". If consensus is not possible, the decision is to be taken by voting. There is the system of one-country-one-vote and decision generally by majority. For very special purposes, higher majority is prescribed. For example, a decision on interpretation of an agreement or on waivers of an obligation needs three-fourths majority. Amendments require two-thirds majority or in some matters acceptance by all countries.
