One of Liam Lawlor's solicitors may be called to give evidence to the Planning Tribunal about the former Fianna Fáil TD's financial dealings.
Anthony Seddon, who has offices in London and Prague, was involved in some of Mr Lawlor's most contentious dealings.
Yesterday, the Planning Tribunal asked Mr Lawlor if he would speak to Mr Seddon to see if he was willing to testify before the tribunal.
The former Dublin west TD said he didn't see the relevance of Mr Seddon's potential evidence.
But the tribunal pointed out that Seddon's solicitors had been involved in several of Mr Lawlor's suspicious dealings.
