There is a race against time as two teams, comprising three representatives each from the camps of Andrew Holness and Audley Shaw, are to meet with the head of the party's secretariat, Dr Horace Chang, to finalise the delegates' list which will be applicable for the November 10 leadership contest.
Sunday Gleaner sources say while progress is being made, it has been slow going as the teams work to complete the list by the constitutionally stated deadline of 30 days before the conference.
This means that the list must be completed this week.
But it's understood that there are frequent stand-offs as the two teams try to ensure that the delegates listed are ones they perceive to be supporting their candidate.
Both teams are reportedly quibbling over the legitimacy of some members whose names have been submitted as delegates by representatives from the other camp.
Holness is represented by parliamentarians Everald Warmington and Shahine Robinson, as well as Delroy Williams, the JLP leader's right-hand man in his West Central St Andrew constituency.
Edmund Bartlett leads the Shaw team, which includes Gregory Mair and Hugh Wildman.
Shaw, last week, blamed Chang for failing to complete the list.
He charged, in a letter, that this was due in part to the JLP general secretary's failure to rigidly follow the guidelines laid down by the Standing Committee in relation to how the list should be created.
Chang told The Sunday Gleaner that approximately 5,600 delegates are expected to be registered to elect the leader of the party at its annual conference come November 10.
He said the Electoral Office of Jamaica, which has been selected to administer the election, will not take on the task unless both sides sign off on the delegates' list.
The creation of the delegates' list became contentious because of the failure of several constituency leaders to register them by the March 31 deadline.
The delegates' lists from each constituency is to be tendered when the constituencies are registered.
