The Left -UPA committee system to analyze the disputative facets of the India-US N-deal and the 123 contract would have its first meeting on Tuesday.

The board will observe whether the final 123 contract treats all worries that the Left parties had brought up in July 2006.

The group is also going to view the disputes between the 123 contract and the divisive Hyde Act, the US statute law that made the Indo-US nuclear transaction possible.

The Left in the interim cognizes that till the board is working, the operationalization of the contract will not start out.

It may therefore recommend two sub-committees- One with technical specialists and the other consisting diplomatists. They may take two weeks for a statement on the Left's worries.

The Left wants to make use of the board to make the government alter its commitment to the existing deal.

D Raja, CPI Leader said, “How can the government say this is informal? It is a formal political committee between the UPA and Left. The findings shall be binding on the government.”

For the administration the board is a platform to turn back the Left's fears over the contract and not a means to adjust its stand.

''We will try to address all concerns of the Left parties and we will like to get it over with quickly,'' said Kapil Sibal, Member, UPA-Left Panel.

Ten days ago, the administration had decided that the committee's conclusions would be factored in operationalization that is why the opposition is in a combative mood.
