Former Irish Nationwide Building Society chief executive Michael Fingleton has lost his challenge to a Central Bank inquiry into alleged regulatory breaches at the society.
Mr Fingleton had argued that he could not lawfully be subject to the inquiry.
His case was rejected by the HIgh Court and this morning the Court of Appeal dismissed his appeal.
He had argued that he had retired before the inquiry was formally started in 2015 and the law did not allow for inquiry into his "past" conduct of the Society's affairs.
The court rejected his claims that the Central Bank lacked jurisdiction and also rejected claims of delay and objective bias.
The Appeal Court also rejected claims that his entitlement to a fair hearing was prejudiced by the bank's publication of details of a settlement agreed with the society itself over the inquiry.
