The Opposition is all set to thwart the ruling party's bid to pass the Bill which seeks trifurcation of BBMP in the Council on Thursday. The combined forces of JD (S) and BJP have petitioned Chairman D H Shankaramurthy to refer the Bill to a joint select committee, reported the Times of India. If the State government does not accept the Opposition's proposal, the latter is likely to demand a voice vote on the issue. The Congress does not have the strength in the Upper House unlike the Assembly where the Bill was cleared without much resistance.It the second time a special session has been called this week. If the Bill gets cleared, the State government will get six months time to conduct the civic elections. However, if the Bill gets defeated in the Council, it will go back to the Assembly where getting a clearance may not pose any hurdle, said The Hindu. If the Bill gets clearance even from the Assembly, the Governor assent is necessary to notify the amendments. The High Court may also deliver its verdict on Thursday on the State government's plea to stay the BBMP polls which a previously a single bench had ordered that it be conducted before May 30.
