Sinn Féin has published details of the motion it will put before delegates at a special Ard Fheis on policing in two weeks time.
Some 2,000 members are expected to attend the conference in Dublin on 28 January.
The motion will ask members to mandate the executive to implement any policy changes.
It also proposes to authorise Sinn Féin ministers to take the ministerial pledge of office which would require them to give their backing to the PSNI.
Gerry Adams has said that the motion would be advocating full co-operation with the PSNI from republicans throughout Northern Ireland.
The Sinn Féin President was speaking on RTÉ Radio's This Week.
The party began consulting its grassroots members today as the party moves towards the special Ard Fheis.
Yesterday, Sinn Féin's 56-member Ard Comhairle voted in favour of convening the conference in Dublin on 28 January.
The party is planning to hold a series of meetings as part of a consultation process.
The DUP has said it would make a positive response to any Sinn Féin endorsement of the PSNI, but has repeated its demand that 'words from Republicans be translated into actions'.
Party MP Jeffrey Donaldson said it was essential for Sinn Féin to give unequivocal support to the PSNI and the courts.
He said the sooner this happened, the sooner all parties could move forward.
The SDLP meanwhile has welcomed the decision by Sinn Féin to hold the special Ard Fheis.
