The investigation centred on whether more than 50 people attended the event. The 80 guests at the dinner were split into separate partitioned areas in order to be categorised as separate gatherings, which was permitted at the time. However, gardaí investigated both the organisers of the golf event dinner in Galway and management at the Station House Hotel in Clifden. Several of the politicians who attended the event were also interviewed by gardaí. The political fallout from the event led to the resignation of then agriculture minister Dara Calleary and six Fianna Fáil and Fine Gael Senators losing the party whip.
