Judgment was reserved yesterday in a High Court action by residents of Kill, Co Kildare, who lost their case against the building of the State's biggest dump, to have the matter referred to the European Court of Justice in Luxembourg.
The residents will seek a stay on the High Court's order rejecting their case if the matter is referred to Europe.
Mr Justice Barr said yesterday he hoped to reach an early decision on the application.
The residents have complained that An Bord Pleanala did not have an environmental impact study on the effects of removal of gravel and sand from the proposed site.
