Frank McBrearty senior has been awarded almost €2.5m by the High Court in respect of damage suffered by his business as a result of garda harassment following the death of Richie Barron.
Mr McBrearty's company had initially submitted a claim for €7.2m.
However, that was reduced to €6m in the course of the High Court case, which was heard in Castlebar, Co Mayo.
The claim included compensation for loss of profits for ten years, loss of business opportunities and loss of capital value.
However, Mr Justice Paul Gilligan made an award for loss of profits for eight years and set the figure at €1.5m.
Mr McBrearty had claimed €3.2m in loss of profits.
The State had admitted liability in the case and the High Court sat to assess the amount to be awarded.
The Judge said he accepted the McBreartys' evidence that they planned to build a restaurant and rooms onto their business and he awarded them €550,000 for loss of opportunities.
Mr McBrearty gave no comment following the judges ruling today.
His High Court action for a personal claim for unlawful arrest, malicious prosecution, unlawful detention and defamation is due to begin in the High court in Castlebar next Tuesday afternoon.
