A jury of seven men and eight women has been sworn in to hear the trial of the former Chairman of Anglo Irish Bank, Sean FitzPatrick, on charges of misleading Anglo's auditors and furnishing false information.

Mr FitzPatrick, 68, from Whitshed Road in Greystones, Co Wicklow, has pleaded not guilty to 21 charges of making misleading false or deceptive statements to auditors and to six charges of furnishing false information between 2002 and 2007.

An expanded panel of 15 jurors was sworn in to hear the trial.

The process of jury selection took around an hour and almost 100 potential jurors were called before the jury was finalised.

The jury will return on Monday but evidence is not expected to begin for about a fortnight while the judge deals with a legal issue.

Before they left, Judge John Aylmer reminded the jurors of their oath to try the case according to the evidence they hear in court.

He warned them not to seek out information about the case on the internet or social media and not to discuss the case with family or friends.

He said this was a very important warning and their decision should be made solely on the basis of what they hear in evidence in court.

Before the jury was selected, Judge Aylmer told the members of the jury panel they should let him know if they believed they were ineligible to serve on the jury.

He said because of the nature of this case, there were a number of additional categories of people who should not serve on the jury.

If they had any strong feelings about the banking difficulties that arose in the State or any strong feelings about the role of Anglo Irish Bank in that crisis, they should not act as jurors, he continued.

The judge told the jury panel that they should not serve on the jury if they knew anyone connected with the case, with Mr FitzPatrick or his solicitors.

He said they should not serve if they had expressed themselves on social media or any publicly available forum on any issue in relation to Anglo Irish Bank, the banking crisis or bankers in general, in such a way that it would embarrass them if it became known.

He said they should not serve if they had such strong views on the banking crisis or had been personally affected in such a way as to interfere with their capacity to be impartial.

The judge told them that people who were active in any campaigning groups or had taken part in particular protests such as anti-austerity protests should rule themselves out.

Judge Aylmer told the members of the jury panel they should not serve either if they had shares in Anglo Irish Bank or directly held shares in other banks or if they were customers of Anglo.

They should not serve, he said, if they had been employed by Anglo or any other financial institution or if they had been employed by or had connections with Anglo's former auditors Ernst and Young - now known as EY.

Anyone qualified as an accountant or auditor or regulated by the regulatory bodies of those professions should not serve, nor should anyone employed by the Central Bank, Financial Regulator, Department of Finance, Department of Enterprise, Jobs and Innovation or the Department of Public Enterprise.

The judge said there would be around 75 witnesses in the trial.

He said the trial was expected to last around 12 weeks and should finish just before Christmas.
