Unite director of legal services, Howard Beckett, said: “Unite applied for an adjournment at the High Court today (Wednesday 4 May) and this was granted by Lord Justice Supperstone until Tuesday 7 June.
“The reason for the application was that the four claimant teams have now become one which meant that it was impractical for the trial, estimated to take 11 weeks, to start on Monday 9 May.
“In addition, some late disclosure has come in from the Information Commissioner’s Office and this evidence needs to be considered and evaluated by our legal team.
“Unite understands that the date for Cullum McAlpine, the alleged architect of the ‘blacklisting’ scandal, to give evidence is Tuesday 21 June.
“Unite still represents about 90 members whose jobs were ruined and lives turned upside down by the ‘blacklisting’ scandal.
“Unite has not reached any settlement although we continue to negotiate to achieve justice.
“The key question that has to be asked of the construction firms, which made an unprecedented admission of guilt last October, is why have they not yet settled?
“Unite continues to seek maximum compensation and justice on behalf of our members following those admissions.”
