The Director for Corporate Enforcement, Ian Drennan, is to appear before the Oireachtas Enterprise Committee to discuss the Sean FitzPatrick investigation.

It comes as Minister for Jobs, Enterprise and Innovation Mary Mitchell O’Connor has given the Office of Director of Corporate Enforcement until 23 June to provide a full and detailed report into what happened with the FitzPatrick case.

Mr FitzPatrick was this week formally acquitted by a jury at the Dublin Circuit Criminal Court on all 27 counts against him.

Judge John Aylmer ruled that he would be directing the jurors to acquit Mr FitzPatrick, who had pleaded not guilty to misleading Anglo's auditors about loans to him and people connected with him.

He said he had made a decision based on law that the prosecution had not established a sufficient case to go to a jury.

In the Dáil this afternoon, Ms Mitchell O'Connor said she is deeply frustrated and shared the disappointment of the other members of the Oireachtas and the public as a result of the judge's decision to acquit Mr FitzPatrick because of shortcomings.

She said: "I agree that the shortcomings here are very serious. I agree that they are unacceptable and it is infuriating for the public. We need to get to the bottom of it."

"This fell far short of the standards, impartial unbiased and thorough investigation that we demand."

She said that he has ordered a report from the current director of the ODCE to find out exactly what went wrong here.

She pointed out that Mr Drennan was appointed as Director of Corporate Enforcement in August 2012, and was not in place at the time the file on Mr FitzPatrick was prepared.

She said: "It is important to note that the criticisms directed at the ODCE by Judge Aylmer regarding the investigative procedures pre-date Mr Drennan's appointment as director."

The Sean FitzPatrick investigation and the ODCE

Earlier today, Fianna Fáil's Niall Collins said the case against Mr FitzPatrick was approached in a botched manner.

There was, he said, a huge lack of capacity on the part of the State about how to bring a prosecution for white collar crime.

"Statement contamination, document shredding, the presumption of guilt rather than innocence, this whole thing was approached in such a botched manner"

He said the Government needed to take a new approach to prosecuting white collar crime.

"You have so many agencies across our landscape to bring white collar crime to heal, but no focus."

"What happens is exactly what we've seen happen with the FitzPatrick fallout. If we have to go ahead and bring in a serious crime agency, let’s move ahead and do it," he said.

He said the reputation of the Office of the Director of Corporate Enforcement was now in tatters.

He said there were also questions for the Director of Public Prosecutions.

Labour leader Brendan Howlin said the failures at the ODCE have been "monumental".

Mr Howlin said the Minister's proposals did not go far enough, and an external review was now required. 

He said an independent investigation into the workings of the ODCE was now required. 

Once the investigation is complete, other agencies with similar powers should also be reviewed, he said.

Sinn Féin's Pearse Doherty said the blame lied with Fianna Fáil leader Micheál Martin for failing to adequately resource the ODCE. 

He said when political corruption was established by tribunals in 2005 the Director of Corporate Enforcement sought additional resources from the Minister of the day, namely Mr Martin. 

"He wrote to Micheál Martin in 2005 and told him that the office of the Director of Corporate Enforcement was wholly inadequately enforced," said Mr Doherty.

"Not one additional staff member was given to the Office of the Director of Corporate Enforcement," he said.

"Bertie Ahern stood where you're sitting today and told them that that they'd have to wait their turn."
