The prospects of Croke Park being opened to soccer and rugby have received a major boost.
Croke Park is now an ultra-modern 80,000-seater stadium
Saturday's Special Congress approved a motion which will prevent senior GAA figures from deciding which proposals can go before the Annual Congress.
Before this year's Congress, the Motions Committee prevented discussion of motions calling for the removal of the controversial Rule 42.
The motions body includes former GAA presidents and other ex-officers.
Before this year's Congress, the Motions Committee ruled that motions from eight counties were out of order.
All eight motions were calling for the GAA's Central Council to be given the power to decide on the Rule 42 issue, which would effectively open the door to soccer and rugby being played at Croke Park.
Under the new regulations, the Motions Committee will still be able to rule motions out of order.
However, from now on counties will be informed in writing what exactly was wrong with their submission.
The county in question can then re-submit its amended motion.
GAA President Sean Kelly backed Saturday's change.
Saturday's vote means that Rule 42 will almost certainly be voted on at next year's Annual Congress.
Calls to open Croke Park have increased since it emerged that rugby and soccer internationals might have to be played in Britain during the redevelopment of Lansdowne Road which is scheduled to start in 2006.
