The marathon 12-hour appeal hearing put representatives of the Irish Sailing Association on the stand, along with the protesting pair, Max Treacy and Anthony Shanks, who are understood to have had a five-strong legal team making their case.
Former Tanaiste and Progressive Democrat leader, Michael McDowell, acted as senior counsel for the Dun Laoghaire pair.
The hearing began at 10am on Saturday, breaking for a one-hour lunch and continuing until after 10pm at the OCI offices in Howth.
The OCI has promised to make its decision as quickly as possible, and it is hoped the outcome will be known by Wednesday.
Treacy and Shanks still have the option to appeal any decision by the OCI to the Court of Arbitration for Sport, which would have to implement a fast-track appeal process to hear the appeal in time. Appeals through CAS can take up to six months to process, however with the Olympics looming, the matter would have to be pushed through.
Afloat.ie has been running a readers' poll on the matter, with 400 voters weighing in almost 4:1 in favour of Treacy and Shanks. Cork sailor Peter O'Leary and his Ballyholme-based crew Stephen Milne were initially selected by the Irish Sailing Association over Treacy and Shanks, despite the latter having the higher world ranking.
