The Planning Tribunal has asked the High Court to order that payment of a bill for some €430,000 in legal fees, due by Liam Lawlor to the tribunal, be enforced.
The tribunal's application asks that payment be enforced by the sale of lands owned by Mr Lawlor or an order for possession of those lands.
The former TD has been issued with a summons to answer the Tribunal's application. The Master of the High Court adjourned the matter to 17 October.
Last December, the Taxing Master gave judgement against Mr Lawlor for a total of €630,000 in respect of legal fees incurred by the Tribunal during various High Court applications regarding his tribunal appearances.
Blackmail allegations
The Planning Tribunal has heard that a former business associate of Liam Lawlor is claiming he was effectively blackmailed into paying hundreds of thousands of pounds.
Counsel for the tribunal, Des O'Neill said former solicitor John Caldwell was claiming he paid £685,000 from two Dublin land deals because Mr Lawlor had blackmailed him into doing so.
The money was paid to Mr Lawlor, disguised as an off shore loan.
Mr Lawlor has told the tribunal he had to take it in the form of a loan because he was in dispute with John Caldwell.
However, Mr Caldwell has told the tribunal the money was never a loan.
The inquiry has also heard that a Jersey solicitor gave false information to the tribunal based on what Liam Lawlor had told him.
Nicholas Morgan has told the tribunal that the former TD was less than frank about the arrangement he had with John Caldwell.
