Sinn Féin president Gerry Adams has told a republican rally that the party will carefully study the St Andrew's proposals before deciding whether they can deliver civic policing and restore democracy.
Mr Adams told the gathering that he knew many republicans were sceptical about whether Ian Paisley would ever share power or operate the all-Ireland institutions, but they had to rise to the challenge.
He said it would be a huge advance to move Dr Paisley and the DUP into agreeing to share power and working the north/south institutions alongside Sinn Féin.
The party would be judging the two government's proposals against that background, he said.
"If Sinn Féin is to respond positively, the proposals must have the potential to deliver accountable civic policing and the full restoration of all the institutions," he said.
Mr Adams also added that there would be differences between republicans on the issues involved, but they should be aired in comradely debate.
