Eamon Ryan, the Green leader and transport minister, is opposed to the proposals being taken forward by Peter Burke, the Fine Gael minister of state with responsibility for planning, the Irish Independent reports.

The disagreement is said to be so sharp that it could destabilise the tripartite coalition of Fianna Fáil, Fine Gael and the Greens, of which the most junior party still holds a significant 12 seats in the Dáil.

Steven Matthews, a Green TD and the chair of the Oireachtas housing committee, has accused Mr Burke of “aiming to exclude people from seeking justice” with this proposals to crack down on what he has termed as the judicial review “industry”.

Tánaiste Leo Varadkar subsequently told Fine Gael TDs and Senators that the reforms “will happen and we are going to make them happen”.
