Wexford county board successfully appealed their hurlers' loss of a home game in next year's Allianz League as a result of breaching rules on training camps.
Davy Fitzgerald's side were among four teams hit by the new stricter regulations surrounding collective training camps during the month of April, following a trip to Portugal.
A prohibition on training weekends or gatherings "of longer duration" more than 10 days before a county is in Championship action was already in the rule book, but a penalty involving the loss of home advantage was introduced at Special Congress last September.
The Waterford hurlers and footballers of Laois and Armagh were also sanctioned following an investigation that originally focused on 17 teams.
Armagh have accepted the loss of one home game in next year's Allianz League, while Laois and Waterford's appeals have not yet been decided.
A Wexford delegation travelled to Croke Park on Monday evening and argued their case, stating that the hurlers' trip was neither sanctioned nor funded by the county board.
A Wexford source also spoke of their frustration that they were to be punished, despite playing three rounds of senior club championship in April.
"Senior Inter-County Panels shall not be permitted to go on Training Week-ends, or training of longer duration, after the Final of their respective National League having been played, except during the 10 days period prior to a Senior Championship Game, or during the 17 days prior to an All-Ireland Senior Final."
Counties who were not training - as Dublin insisted they were not on their team-bonding trip to the battlefields of World War One - or those who could perhaps show that they had only been away for one night escaped censure.
The GAA privately accept that the wording of the rule needs to be reworked.
