Andhra Pradesh government will file a special leave petition (SLP) in the supreme court challenging the Krishna water disputes tribunal's award on sharing of Krishna river water between riparian states Maharashtra, Karnataka and AP.

Simultaneously, it will also file a petition before the justice Brijesh Kumar-led tribunal seeking clarifications on its order delivered on December 30 last.

This was decided at an all-party meeting held here late this evening. At the meeting chaired by chief minister N Kiran Kumar Reddy, political parties wanted him to lead an all-party delegation to prime minister Manmohan Singh to apprise him of the damage done to the state by the award.

The state government appointed senior advocates K Parasaran, Harish Salve and G Umapathy to plead its case both in the supreme court and before the tribunal.

Putting forth suggestions for protecting the riparian interests of the state, the political parties wanted the state government to argue the case effectively.

It was only because of the ineffective arguments by the Government last time that the tribunal?s award went against the state, putting many irrigation projects on river Krishna as well as agriculture under the Nagarjuna Sagar command area in jeopardy, the parties alleged.

The chief minister assured the political leaders that their views and suggestions would be incorporated in the state's case in the apex court as well as the tribunal.

Leaders of the ruling Congress, main opposition TDP, TRS, BJP, CPI, CPM, BJP and Lok Satta attended the meeting, where ministers P Sudarsan Reddy, Manikya Vara Prasad and K Parthasarathi were also present.
