evidence: In the mid-fifties, the construction of the Tortkul reservoir and the Tortkul canal was projected. In some places the channel of the canal had to pass through the territory of the Isfara region of the Tajik SSR. [...] For unknown reasons and according to the results of the commission's work, it was proposed to transfer several thousand hectares of the territory belonging to the Isfara region to the Republic of Kyrgyzstan. In return, the Kyrgyz side was supposed to use the Tortkul reservoir as an inter-republican one and assist in the irrigation of about 3.5 thousand hectares of land in the Isfara region. Nevertheless, this parity commission's protocol could not acquire legal force because the Presidium of the Supreme Council of the Tajik SSR did not ratify it and rejected the document. [...] Following the results of their trip, the deputy group additionally studied all the available archival documents in Moscow and presented a conclusion confirming the legal rightness of the Tajik side on the restoration of territorial justice in the division of territory between the Tajik SSR and the Kyrgyz SSR. Moreover, the proposal confirmed that Vorukh was never an enclave and historically related to Isfara region on the territory belonging to the Tajik side.
