Sinn Féin members in the Dublin South West constituency have been ordered to stop all meetings and suspend all political activity.
It's after its councillors nominated Paddy Holohan for the job of Mayor of South Dublin following his suspension from the party.
Sinn Féin's local branch members in the area were told of the decision in a letter, made public late last night, from Ken O'Connell, the party's political director south of the border.
Councillor Holohan had been suspended from the party for comments he made on his podcast about then-Taoiseach Leo Varadkar's family ties in India,.
The party's president Mary Lou McDonald called the remarks "beyond offensive" when they surfaced during the general election campaign.
Party officials now plan a full review of the constituency.
