A court was told that a row between Inland Fisheries Ireland and 40 men and a woman over fishing rights on the Gweebarra River remains unresolved.
Dungloe District Court heard the case against six of the people was part-heard but must go back before Judge Denis McLaughlin for completion.
All cases involve a total of 137 charges of illegal fishing on the Gweebarra River system in the Doochary area of Co. Donegal. Some of the summonses date back to 2008.
Dungloe court was told there was a decision in the High Court about aspects of a number of cases but there had been an appeal to the Supreme Court.
Judge Paul Kelly adjourned all cases to June 11 when it is hoped to establish when Judge McLaughlin will be available to complete hearing of the six cases before him.
Judge Kelly said when those six are completed he will adjudicate on the remaining summonses.
