The Department of the Environment has said an internal review of planning decisions by a number of local authorities is still not completed.
These included high rise planning permissions in Dublin, like Sean Dunne's Ballsbridge plan and a relief road scheme in Co Carlow.
The road in Carlow was first highlighted in 2008 and led to a compensation case costing a total of €11 million.
A spokesman for the Department said the review of controversial planning decisions made by Dublin City and Carlow councils as well as Cork City and County, Galway and Meath is being finalised.
The previous Environment Minister John Gormley had announced an independent investigation into all six authorities in June 2010 following a series of complaints.
However present Environment Minister Phil Hogan, whose constituency includes Co Carlow, said he regarded the complaints as mostly "spurious" and abandoned plans for the independent investigation after he took office.
It was confirmed in June last year that an independent review would be carried out and a report published "shortly".
Nine months later a spokesman for the department said it could still be a number of months before a statement on this review will be made and that it had not been decided if details of the review would be made public.
