They want the government to debate the appointment of Supreme Court Judge Seamus Woulfe.
The Dáil's business committee is on the verge of collapse after opposition parties walked out.
The seven opposition groupings say they won't take part in any more meetings until the government agrees to hold a debate on the appointment of Supreme Court Judge Seamus Woulfe.
The business committee schedules what the Dáil talks about and debates and this marks a significant breakdown in the relationship between government and opposition.
Aontu leader and Meath West Peadar Toibin earlier asked if the position on the Supreme Court was part of political horsetrading between Fine Gael and Fianna Fáil:
