contradiction of iranian rail transport regulations with principles of world trade organization (wto)

general agreement on trade in services (gats) -as one of the most important agreements of wto- provides some principles and commitments on services such as rail transport services. countries applicants for accession to wto have to correspond their legal and economic structures in the field of this section with gats principles. however, working groups of applicant countries can make some exemptions on flexible principles of gats because some principles of services section are flexible. iran, as an observer of wto has to identify contrasts of rail transport regulations and laws with principles of gats and provide legal suitable and effective solutions. however, this important issue has not been studied in iranian legal literature; therefore, this article tries to consider gats principles and iranian contrast regulations and suggest suitable and practical solutions to the legislator and working group.
