Career
Seán McCague served as the 33rd President of the Gaelic Athletic Association (2000–2003). As President he will be mostly remembered for the removal of Rule 21 in November 2001. The rule was abolished despite the opposition of five of the six northern counties (Antrim, Armagh, Derry, Fermanagh and Tyrone).
At the annual 2001 Gaelic Athletic Association Congress McCague convinced Taoiseach Bertie Ahern to pledge €76 million towards the redevelopment of Croke Park.
This amount was later reduced to €38 million.
