An Bord Pleanala has granted planning permission for developer Liam Carroll's North Quay Investments Limited to complete the building of the proposed Anglo Irish Bank headquarters in the North Lotts area of Dublin's docklands.

Originally Anglo provided the funding for the development to Carroll's company NQIL and was to rent part of the development as its intended new headquarters.

In 2007 the Dublin Docklands Development Authority fast-tracked planning permission to Mr Carroll on the condition that he give some land on the former Brooks Thomas site on North Wall Quay back to the Authority so it could build a park.

As part of the deal, the Authority said it would later push for changes to the planning scheme for the area, so further development could take place.

The permission was for an eight-storey office development and was outside the DDDA's own planning guidelines for density in the North Lotts area.

The Authority's confidential agreement with Mr Carroll later caused the High Court to quash planning permission for the development, when rival developer Sean Dunne took a case that led to a ruling that the secret agreement between the planning authority and Mr Carroll gave rise to a 'reasonable apprehension of bias'.

The fast-track permission was invalidated by the High Court and construction stopped on the site.

A new application was made to Dublin City Council to retain the building in its current, unfinished state, and permission for all other works, including facades to be finished.

Dublin City Council gave notification of a decision to grant permission on January 2 2009. This was appealed by Sean Dunne's North Wall Quay Property Development later that month.

The appeals and court cases mean the building has been standing unfinished on Dublin's quays for several years.

But permission has now been upheld to retain and to finish the building.

As planning permission has been upheld, the only option open to Sean Dunne is to call for a judicial review of the decision.
