Washington: A legislation to implement the historic Indo-US civilian nuclear deal appeared to have hit a roadblock when Conferees of the House of Representatives and Senate failed to file a final report with Rules Committee prior to the consideration of the House.

At one time yesterday, there was the thinking that the Conferees' committee had agreed on the final version of the legislation that had to clear both the House and the Senate before the Congress adjourns this week for the year to meet in January.

One version doing the rounds is that the legislation has become a victim of lame duck politics in the sense that lawmakers are eager to tag legislations that have nothing to do with India or the terms and outlines of what the Conferees have already arrived at.

The first step before being taken up on the House floor was that the Conference Report must be filed with the Rules Committee. That has not happened as of late last night and for reasons unknown. Senior staffers on the Capitol Hill feigned ignorance as to the details of the procedural 'roadblock'.

According to sources, Republican Majority Leader in House of Representatives John Boehner appeared to be interested in attaching legislations not related to the India Bill.

However, Kevin Smith, spokesperson of Boehner, said he did not know what was holding up the legislation as lawmakers are still working on it.
