|The purpose of this thesis is to discuss the limitation of participation of developing countries in the World Trade Organization’s (WTO) Dispute Settlement Body (DSB). Under the DSB, there are many cases that present the limiting of developing countries on some significant ways. This thesis discusses the most significant limiting factors reported and practiced by developing countries in the DSB. Developing countries have a lack of financial and legal resources and ability to impose the DSB rulings on procedural of the DSU. Also, there are a number of significant procedural reforms that the DSU dispute settlement system must consider. This thesis discusses these legal and financial obstacles for developing countries under the DSB. This thesis mentions the most significant potential solutions for tackling the constraints of developing country participation in WTO dispute settlement proceedings. Those solutions try to make the WTO system more workable for developing countries in settling disputes. In addition, it tries to demonstrate the significance of reforming the DSU. Also, it tries to improve developing country use of the WTO DSB. Therefore, it recommends that the proposals appearing in this thesis should be used in actual practice by establishing them in the DSB.
