The High Court will give its judgment tomorrow in the application by the widow of former TD, Liam Lawlor, to stop the Mahon Tribunal going ahead with its investigations into the rezoning of lands at Quarryvale in west Dublin.
The tribunal is due to begin the Quarryvale Two module of its investigations with an opening statement on Monday.
The Taoiseach, Bertie Ahern, is due to be called as a witness in the module.
However, Hazel Lawlor is taking legal proceedings to stop the tribunal from making findings against her or her late husband without evidence proved beyond reasonable doubt.
She wants to stop the module from going ahead until that legal challenge is heard.
This morning, Mrs Lawlor's Senior Counsel, Martin Giblin, said his client was in dire financial circumstances and the tribunal could not ignore that fact.
The court was told there were six judgment mortgages registered against Mr Lawlor's estate.
These related to an order of costs made against Mr Lawlor in his lifetime relating to legal proceedings he took against the tribunal.
Mr Justice Iarfhlaith O'Neill said he would endeavour to give his judgment at 11am tomorrow morning.
