Two companies of which property developer Mr Jim Mansfield is a director have undertaken before the High Court to remove a huge mound of earth placed along the boundary of Weston Aerodrome, near Lucan, and to restore the affected lands to their original condition.
The aerodrome was bought by Mr Mansfield earlier this year for some €12.7 million.
South Dublin County Council had sought the undertaking, claiming the mound, which is about two metres high, was not exempted development and required planning permission.
The council also contends a range of other works have been carried out at the aerodrome without permission.
On foot of the undertaking, Mr Justice Ó Caoimh adjourned for three weeks an application by the council for an interlocutory injunction - an injunction applying pending the determination of legal proceedings - seeking a range of orders against Fallowvale Ltd and Weston Ltd.
In the interlocutory application, the council will seek orders restraining the companies and their servants or agents from carrying out or continuing to carry out any development at lands at Weston Aerodrome unless and until planning permission has been obtained.
The council also wants orders requiring the companies to cease all unauthorised development at the site.
This includes the laying out of a car park, the extension of a bungalow and taxiway, the construction of new hangars, the erection of security fencing, the installation of a waste water treatment plant and fuel storage tank and the construction or use of a storage shed adjacent to the hangars.
Mr Dermot Flanagan SC, for the council, said its concern was that it had entered into a contract with a company in relation to a water supply scheme and the mound would interfere with those works. The matter was urgent.
