The DUP amendments to the Local Government (Disqualification) Bill were opposed by Sinn Féin, the SDLP and the UUP, on 9 November 2010.
For Sinn Féin, Alex Maskey said that his party could not support amendments three and four, which delay the implementation of the bill until 2014, because they could see no justification for extending dual mandates beyond the elections in May 2011.
He added that amendment five, which would reduce allowances to those on dual mandates was not specific about how and by how much they would be reduced.
Proposer of the bill Dawn Purvis accused the DUP of "a meaningless attempt to kick the bill into Never Never Land".
She urged the DUP and the Alliance Party to put aside personal ambitions and consider the effect the legislation would have on the institutions in years to come.
Winding for the DUP Peter Weir said that he found arguments that double jobbing was unacceptable in the current economic climate "utterly spurious".
He added that Dawn Purvis had misinterpreted the interim arrangements provided for by amendment five, which he insisted could be implemented from 2011.
Amendment three was defeated by 52 votes to 40.
Amendment four was defeated by 53 votes to 40.
