匈牙利案(英文介绍)
On 16 September 1977, a treaty concerning the construction and operation of the Gabcikovo-Nagymaros system of locks was signed by Hungarian People’s republic and the Czechoslovak people’s republic. The treaty entered into force on 30 June 1978, it provides for the construction and operation of a system of locks by the parties as a “joint investment ”. At the same time, by the terms of the treaty, the contracting parties undertook to ensure that the quality of water in the Danube was not impaired as a result of the project.
However, as a result of intense criticism which the project had generated in Hungary, the Hungarian government decided on May 1989 to suspend the works at Nagymaros pending the completion of various studies which the competent authorities were to finish before July 1989. Lastly, on 1989, Hungary decided to abandon the works at Nagymaros and to maintain the status quo at Dunakiliti.
During the period, Czechoslovakia started an alternative solution named “Variant C”, which included the construction at Cunovo of an overflow dam and a levee linking that dam to south bank of the bypasss canal.
On 1991, the Slovak government decided to begin the construction of the project. Then Slovak requested the court to decide “whether the Hungary was entitled to suspend and subsequently abandon the project for which the treaty attributed responsibility to Hungary”.
