The FAI is at risk of losing government funding after a proposal to help the FAI achieve a required gender balance on its board was rejected.
All sports associations must have at least 40 percent women on their boards by the end of the year.
Having struggled to achieve this among its current 12 directors, four of whom are female, the FAI sought to resolve the issue by expanding the board to 14 members.
This proposal required 75 percent approval, but only 67 percent of the General Assembly voted for it.
A statement said: “The FAI Board will now reflect on the decision, work through the next steps and present a revised position to the General Assembly for consideration at the Annual General Meeting on December 9th.
“It remains the FAI’s firm position to achieve the required proportion of women on the board of 40 percent.”
If this does not happen, the club risks losing 4.3 million euros in state funding.
