Sinn Féin President Gerry Adams has indicated he continues to believe that a shift in the party's policing policy is the right thing to do.
He was speaking on the eve of an important meeting of Sinn Féin's national executive.
But in a statement today, Mr Adams also accused the DUP of failing to honour commitments it had made in relation to a timeframe for the devolution of justice and policing powers.
The Sinn Féin President claimed that in advance of his party's executive two weeks ago the DUP had been given the text of a motion about policing that Mr Adams would put to that meeting.
He also suggested that after Sinn Féin's executive backed that motion, the DUP failed to deliver its promised response.
He said the DUP had backed off its deal to support the devolution of policing and justice within a set timeframe.
But the DUP leader, Ian Paisley, denied that his party had backtracked. He said he made no commitment that went beyond his recent public statements.
Dr Paisley said he was not in the business of saying one thing in public and another in private.
He added it is time for Sinn Féin to get down to business and deliver support for the police, the courts and the rule of law.
Tomorrow afternoon, Sinn Féin's executive will debate whether to press ahead with an Ard Fheis on policing.
