Jamaica Labour Party (JLP) member Everald Warmington has filed an application in the Supreme Court seeking an injunction to bar the election of three front-runners for the posts of deputy leader tomorrow.
Given the urgency of the matter, it is set for hearing today.
Warmington is contending that under the party's constitution, Christopher Tufton, Audley Shaw and Desmond McKenzie were not properly nominated to be elected JLP deputy leader.
McKenzie is slated to represent the JLP region one; Shaw, region three; and Tufton region four.
According to Warmington, only James Robertson from the JLP region two was duly nominated.
He said that under the JLP's constitution, the candidates must be nominated 30 days before the annual conference.
McKenzie was the last to be nominated Sunday.
It is not clear when the other contenders were nominated.
Warmington has named JLP Leader Andrew Holness, General Secretary Aundré Franklin and acting Chairman Robert Montague as the respondents.
The application was called up for hearing in chambers yesterday but was put off to allow the respondents to be served with court documents so that they can be represented today.
