The SDLP wants the GAA to investigate why Sinn Féin was allowed to use its facilities in Co Tyrone last weekend to stage a hunger strike commemoration rally.
The event was held at the GAA grounds in Galbally on Sunday afternoon and Sinn Féin President Gerry Adams was the main speaker.
Northern Ireland Minister for Culture and Sport Nelson McCausland (DUP) has claimed that the rally was a clear breach of the GAA's rule 7a, which states that the organisation should be non-party political.
SDLP deputy leader Alasdair McDonnell has also criticised the event.
He said he would raise the issue when he met senior GAA executives in Dublin today.
