The GATS expressly recognizes the right of members to regulate service delivery by pursuing their own policy objectives. However, the agreement contains provisions to ensure that service rules are managed appropriately, objectively and impartially. The GATS agreement has been criticized for replacing the authority of national law and justice with that of an GATS dispute resolution body that holds closed hearings. Spokespeople for WTO government members have an obligation to reject this criticism because they had previously pledged to recognize the benefits of the dominant trade principles of competition and „liberalization. It is a foreigner who provides services such as a doctor, a nurse, a computer engineer, etc., who works as a consultant, collaborator, from one country to another. In addition, the Air Services Annex exempts air duty and service measures directly related to the exercise of these rights. Exceptions may be granted in the form of Article II exceptions. Members could apply for such exemptions before the agreement came into force. New derogations may only be granted to new members at the time of accession or, in the case of current members, by a derogation under Article IX:3 of the WTO agreement. All exceptions are subject to review; they should not, in principle, last more than 10 years. In addition, the GATS allows groups of members to enter into economic integration agreements or to mutually recognize regulatory standards, certificates and others when certain conditions are met.
The provision of many services often requires the simultaneous physical presence of the producer and the consumer. There are therefore many cases where, in order to be commercially reasonable, trade obligations must extend to cross-border consumer movements, the establishment of a commercial presence in a market or the temporary free movement of the service provider. This definition defines virtually all public services as „commercial“ and already covers areas such as the police, the military, prisons, justice, public administration and government. In a relatively short period of time, this could apply to the privatization or commercialization of a large part, and perhaps to all those who are now considered public services that are currently considered social requirements for the entire population of a country, structured, marketed, under-distributed to for-profit suppliers and ultimately fully privatized and are only available to those who can pay the price.
