On 27th May 2010, we had dealt with the arbitration between Pakistan and India in relation to the Indus Water Treaty, 1960.We had stated that Pakistan had invoked arbitration under the said Treaty alleging that India's plan to build the Kishanganga Hydroelectricity Project was contrary to the Treaty. We had also stated that Pakistan had appointed Jan Paulsson and Justice Bruno Simma as arbitrators.
The Hindu has reported that the Indian government, after consulting with lawyers R.K.P. Shankar Dass and Fali Nariman (both the said lawyers were reportedly involved in the Baglihar dam dispute under the same Treaty) has planned to appoint Peter Tomka, a judge of the International Court of Justice, and Lucius Caflisch, an academician as India's arbitrators.
As per the Treaty, each party to the arbitration is to appoint two arbitrators and the four arbitrators so appointed would appoint three arbitrators. The Hindu states that India is supposed to respond within 30 days from the receipt of the notice by Pakistan invoking arbitration. It seems India has received it on 18th May and has to respond by 17 June.
