The High Court today reserved judgment on a challenge by Detective Sergeant John White to a decision of the Morris Tribunal to hear detailed evidence about his medical health in public.
The court was told Det Sgt White suffered from "extreme stress and anxiety". He contends he is unable on medical grounds to appear before the tribunal but the tribunal has brought a separate application claiming Det White is in contempt of a summons to appear before it.
The court will determine the tribunal's application later.
In September last, Det White failed to answer a summons to appear at the tribunal, which was told he was too unwell and in hospital.
He was due to give evidence in relation to allegations made by Ms Rosin McConnell that she was verbally abused and pushed by the Detective after she was detained by gardai. Det White rejects the allegations.
In his proceedings, Det White claims the decision of the tribunal to hear the evidence relating to his medical health in public is a breach of his constitutional rights.
The President of the High Court, Mr Justice Joseph Finnegan, said he hoped to give a decision on the matter by the end of next week.
