Forthcoming Lord of the Dance shows could "fall apart" because of an injunction to prevent creator Michael Flatley from participating in the production, the High Court in Belfast has heard.
Counsel for the star also claimed that he would be subjected to "economic havoc" if an action brought by the entertainment company that now runs the tour is dismissed.
Switzer Consulting is suing the choreographer and dancer for alleged breach of contract.
The case centres on an agreement they were said to have reached in 2024, alllowing the firm to run Lord of the Dance.
Earlier this week, Switzer obtained a temporary injunction to stop Mr Flatley from interfering with the shows.
Today, his lawyers questioned whether the interim order should have been granted at an ex-parte hearing at which the star was not represented.
Barrister John Coyle argued that the retired performer's participation and artistic direction is a vital component in the production.
"There is a show in two weeks and unless Mr Flatley is able to communicate to the dancers these shows are in grave danger of falling apart," he said.
The 67-year-old, who first rose to fame in Riverdance in 1994, went on to create Lord of the Dance two years later.
In affidavits lodged in court, Switzer made allegations about Mr Flatley’s financial reputation and sought to have him blocked from playing a role.
As part of the wider case, undertakings have been given to pay any consequent damages if the action is unsuccessful.
However, Mr Coyle claimed there may be issues over the solvency of the company.
"The economic havoc that would be visited upon the defendant is substantial, without any recompense," he submitted.
Arguing that Mr Flatley does not know what was said about him at the previous hearing, counsel also suggested that press coverage of the case would be libellous if based on anything other than official affidavits.
Mr Justice Simpson responded that anything referred to in court documents is in the public domain.
"I haven’t read (newspaper reports), this is not being tried in the public arena," he added.
Counsel for Switzer, Gary McHugh, acknowledged an urgency in dealing with the dispute over the injunction.
"We reserve our position on any extension that may be sought," he told the court.
Listing a further hearing later for this month, the judge told both sides: "If there is a show in two weeks we need to be dealing with this quickly.
"At the moment the injunction stands as granted," he added.
