Vyas said a representative of the Narmada Bachao Andolan (NBA), whose leader Medha Patkar is a member of the commission, would be making a presentation at the session. He pointed out that the NBA was also a party to the dispute over the Sardar Sarovar Project (SSP) on Narmada river, which was pending before the Supreme Court.

The Minister said the commission would, in all, hold eight sessions during its hearing on large dams in South Asia, which is scheduled for September 21 and 22. While seven hearings would be of a general nature, one would focus on `Large dams and alternatives in India's Narmada River Valley', he said.

TheGovernment, which has been opposing the WCD visit, regards the session on Narmada as further evidence of its suspicion that anti-dam activists have hijacked the commission. Vyas today wrote another letter to the WCD Chairman, requesting him to cancel the public hearing and the visit to India, ``which has already developed into an unfortunate controversy''.

Vyas drew Asmal's attention to his letter to the Chief Minister on September 4 in which he had said the commission ``would not -- under any circumstances -- seek to adjudicate on specific projects'', as its primary purpose was ``to facilitate a review of lessons learnt with existing dams, in general''.

The decision to hold a session exclusively on the Narmada showed that this assurance had been violated, Vyas said, adding, ``perhaps this programme was fixed up relying upon the advice of your members from India who seem to have succeeded in bringing this controversial subject under a sharp focus at the most inappropriate time''.

Vyas also questionedWCD secretary general Achim Steiner's claim that the commission's visit had been planned in ``full consultation'' with the Indian authorities, and had the ``approval'' of the Indian High Commission in South Africa, the Planning Commission and the Madhya Pradesh Government.

According to Vyas, the commission never obtained the approval of the Government of India, which alone could allow such visits. The commission did write to the Planning Commission, which wrote back that the matter fell in the purview of the Ministries of Water Resources and Power.

Vyas also wrote to Planning Commission Deputy Chairman Jaswant Singh, requesting him to communicate the Government of India's views on the proposed WCD visit to Asmal ``at the earliest''. He told Singh that a delegation, led by Chief Minister Keshubhai Patel, had briefed Prime Minister Atal Behari Vajpayee about all aspects of the matter yesterday.

The delegation was told that since the communication from Asmal was addressed to the Deputy Chairman of thePlanning Commission, it would be appropriate that a reply was sent by the Planning Commission, ``indicating our view that this is not the appropriate time'' for the visit. ``I am sure, by now, you must have received the necessary communication from the PMO'', he said.

Government sources clarified that earlier reports of the Ministry of Water Resources having sent a letter to the WCD, asking it to cancel the visit, arose from a ``communication gap''. All that happened was that the Ministry had sent the draft of a letter to the PMO for approval, sources said.
