The leader of the Aontú party has withdrawn his bid to seek an injunction stopping the broadcast of the political party leaders debate on RTÉ's Claire Byrne Live tonight.
Counsel for Peadar Tóibín, Louis Masterson, informed the High Court this afternoon that the "injunction application will not be proceeding."
He also told Ms Justice Leonie Reynolds that they had "advised RTÉ of the fact."
Earlier today, Mr Masterson told the High Court that Mr Tóibín was to seek an injunction preventing the broadcast from going ahead.
Counsel told Ms Justice Reynolds that he hoped to be in a position to formally apply for the injunction against RTÉ this afternoon and that the legal documents required were being prepared.
The court was told that the action was being taken arising out of Mr Tóibín's "exclusion from the debate" by the national broadcaster.
The leaders of seven political parties are due to participate in the debate, which is being broadcast from NUI Galway tonight.
Speaking outside the High Court, the Aontú leader said there were "very tight timelines" around the party's ability to launch "a proper challenge and injunction against RTÉ."
Mr Tóibín said "unfortunately we hadn't the means to be able to proceed with the injunction to our satisfaction."
He said it was "just not feasible" given the fact that "there is a massive amount of work putting the papers together and getting the court case in order and given the tight timeline to do that."
Mr Tóibín said he "disagrees radically" with the criteria set out by RTÉ for selecting the seven parties that will take part in the debate.
He said Aontú believes "all the political parties should have an opportunity to stand in the studio tonight and set forth policies and party objectives."
