Once a gazette notification is issued, institutions like the Cauvery River Authority (CRA) chaired by the Prime Minister and the CMC will cease to exist.
The Tribunal, comprising chairman Justice N P Singh and members N S Rao and Sudhir Narain, in a unanimous award in February 2007 had determined the total availability of water in the Cauvery basin at 740 thousand million cubic (TMC) feet at the Lower Coleroon Anicut site.
The proceedings of the Tribunal, set up in June, 1990, went on for more than 16 years.
In, what was then described as a balancing act, the Tribunal gave Tamil Nadu 419 TMC of water (as against the demand of 562 TMC); Karnataka 270 TMC (as against its demand of 465 TMC); Kerala 30 TMC and Puducherry 7 TMC.
For environmental protection, it had reserved 10 TMC.
The Tribunal's award will come into effect within 90 days of its notification by the Centre. As per law, the award comes into being after being notified by the Centre through its publication in a gazette.
