New Delhi, March 15: The government is not leaving anything to chance in ensuring that the Aadhaar Bill clears Parliament tomorrow, the last day of the first part of the ongoing budget session.

All BJP members in both Houses have been told to be present in Parliament till late in case the Opposition in the Rajya Sabha manages to get an amendment passed.

The Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Bill, 2016, is scheduled for consideration and return by the Rajya Sabha tomorrow.

Since it has been designated a Money Bill by the Lok Sabha Speaker, the Rajya Sabha cannot hold it back. However, if an amendment is cleared by the Upper House, then the Bill has to go back to the Lok Sabha for the amendment to be either accepted or negated.

Several members, including those from the Left and the Congress, have moved amendments to the Bill.

The CPM, in particular, is hopeful that if one amendment is cleared by the Rajya Sabha, then it would give the Opposition some time to think up a strategy on how to deal with the increasing use of the Money Bill route by the government to sidestep its minority status in the Upper House.

The CPM calculation is that an amendment by the Rajya Sabha would force the government to defer the final passage of the Bill for the post-recess part of the Budget session.

While there appeared to be no clarity or coordination within the rest of the Opposition, the government's floor managers are preparing for such an eventuality.

At the BJP parliamentary party, all MPs were told to be in Parliament till the very end of proceedings tomorrow so that if the Opposition in the Rajya Sabha manages to get an amendment in, then the Bill can immediately be referred to the Lok Sabha for negating it.

This has left many a BJP MP in the Lok Sabha fretting as most had planned to leave Delhi by tomorrow evening. Now they have to reschedule even as some Opposition members wondered about the futility of getting an amendment passed just to flex muscle in the Rajya Sabha when it is bound to be negated by the Lok Sabha.

"What is the purpose of such an amendment?" asked an Opposition member who was not quite sure if the Lok Sabha would even need to consider such an amendment.

According to former Lok Sabha secretary-general Subhash Kashyap, if the Rajya Sabha clears an amendment, then the Bill would have to be referred back to the Lok Sabha to either accept or reject the change.
