A firm which once formed part of bankrupt billionaire Sean Quinn's business empire has been blocked from suing in Northern Ireland over a road-building project in the Republic.
Quinn Building Products Ltd is claiming more than £250,000 for tarmacing work carried out on a Co Cavan scheme.
But a judge at the High Court in Belfast stayed proceedings north of the border after deciding he has no jurisdiction to hear the case.
Based in Derrylin, Co Fermanagh, Quinn Building Products is now part of the re-branded Aventas Group.
It was sub-contracted by civil engineering company P&S Civil Works Ltd for the Cavan Town Eastern Access Road Construction Project.
A dispute has now arisen over money allegedly due as part of the arrangement.
With the contract engineer having raised issues over the tarmac works carried out by Quinn Building Products, a dispute has arisen over money alleged due.
But in an application to stay the proceedings, P&S argued that the sub-contract was performed in the Republic.
The company further contended that it's own location in Co Cavan strengthen the case for Northern Ireland having no jurisdiction in the case.
Quinn Building Products countered by claiming the deal was formed in Northern Ireland.
Negotiations in 2011 were undertaken at offices on both sides of the border, the court heard.
However, Mr Justice Weatherup held that no consensus was reached on jurisdiction resting in Northern Ireland.
In a newly published judgment he said: "The regulation provides that jurisdiction lies in the Republic as the domicile of the defendant (P&S) and the place of performance of the contract.
"Jurisdiction does not lie in Northern Ireland. Accordingly I stay the proceedings in Northern Ireland."
