Munda, the former chief minister, raised the objection when Speaker C P Singh announced in the house that he had left the issue of voting to the conscience of the MLA, who is serving a life term in a murder case, whether he would participate in the confidence vote or not.
He read out from a copy of the recent judgement by the apex court that said persons with criminal backgrounds serving prison terms or were in police custody shall not vote in any election.
Singh told the house that he had sought advice from Advocate General M S Anwar, who said the Supreme Court judgement did not affect the MLA's right to cast vote and he was entitled to participate in the voting.
"I have left it on the conscience of the MLA," the Speaker said adding the matter was closed.
The Ranchi District and Sessions court had on May 13 convicted Lakra and three others for killing a youth, who was allegedly in love with Lakra's niece and the two had decided to marry, and awarded them life in prison.
