Richard Bruton says the European Commission is "prosecutor, judge and executioner"
Meetings between Independent ministers and various Government officials on the Apple tax ruling continued into this evening.
Ministers and TDs from the Independent Alliance met this afternoon to discuss their position, but the meeting ended after over an hour.
The group, which has two ministers at Cabinet, are to continue discussions on various fronts and are expected to make a decision in advance of tomorrow's 11am Cabinet meeting.
Independent Children's Minister Katherine Zappone also held a round of meetings with officials and the Attorney-General.
She has refused to be rushed into making a decision, but does support a decision being made at tomorrow's Cabinet meeting.
It comes as a member of the Cabinet says the European Commission has set itself up as "prosecutor, judge and executioner" in relation to the ruling.
Meanwhile, the European Commissioner behind the ruling has rejected claims it was a political decision.
The war of words following the Apple tax ruling continues, with the tech giant boss Tim Cook today describing it as "political crap".
Mr Cook said he was "very confident" the ruling would be overturned on appeal.
That has led to a hit back from the European Commissioner who oversaw the ruling.
Commissioner Margrethe Vestager is insisting her ruling is based completely on facts which can be tested in the European Courts.
But the claims of the commission overstepping its powers are also coming from within the Cabinet.
Education Minister Richard Bruton has accused it of a power grab.
He has also denied there is a rift in Cabinet between Fine Gael and Independents.
Fine Gael are demanding Ireland launch an appeal to the European courts.
