The Opposition has hailed the Lawlor court decision as a major political landmark, with Fine Gael and Labour calling on Fianna Fail to take further action against their former deputy.
Fine Gael last night demanded Mr Lawlor's resignation from the Dail. Failing that, the party's justice spokesman, Mr Alan Shatter, called on the Taoiseach to arrange for a Dail vote to remove Mr Lawlor from the Dail committees on which he serves.
He said that had his party not tabled a motion to remove him as vice-chairman of the Finance and Public Services Committee, "Deputy Lawlor would today still be a committee office holder at the behest of the Taoiseach".
Mr Lawlor resigned from that post last week, faced with the prospect of losing the vote on the Fine Gael motion.
The Labour Party leader, Mr Ruairi Quinn, said the High Court decision on Mr Lawlor was "a vindication of the tribunal of inquiry and conveyed a clear message to all citizens, and especially elected public representatives, that tribunals of inquiry established by the Oireachtas were entitled to the full co-operation of everyone".
He called on the Government to "address its relationship with Deputy Lawlor. Deputy Lawlor continues to operate and work from a Fianna Fail office; Fianna Fail continues to claim parliamentary allowance in respect of him. Despite all that he has done, Deputy Lawlor continues to remain a member of the Fianna Fail family. Is this acceptable?"
He said the Tanaiste, Ms Harney, once said she would not remain a member of a Government dependent on anybody who was guilty of wrongdoing. "Deputy Lawlor has been found guilty of serious wrongdoing by the High Court. What has the Tanaiste to say now," he asked.
The Minister for Agriculture, Mr Walsh, said last night it was "very sad" that Mr Lawlor had been jailed by the High Court. Mr Walsh said the Dublin West TD should purge his contempt of court and co-operate with the Flood Tribunal.
"The terms of reference of the tribunals which were established by the unanimous will of the Oireacthas have to be complied with," he told RTE's Questions and Answers.
"It's very sad when anybody ends up in jail," Mr Walsh said.
"The sooner Liam purges his contempt and gets back before the tribunal the better."
