Papers accumulated by the Ansbacher Inspectors in relation to Mr John Murphy, chairman and major shareholder in the J Murphy & Sons group of building and civil engineering companies, are among those to be given to the Revenue following yesterday's Ansbacher ruling.
Mr Murphy (81) is a brother of the late Mr Joe Murphy, who gave evidence to the Flood (now Mahon) Tribunal in Guernsey in 1999 regarding his company, JMSE, and payments to Mr Ray Burke.
The two Kerry-born brothers emigrated to Britain around the time of the Second World War and set up separate building groups that became extremely successful.
J Murphy and Sons Ltd is a London based holding company for a group that includes Murphy International, which has offices in Newbridge, Co Kildare.
The group's website says it made a profit of £9 million (€13.6 million) on a turnover of £225 million in 2001, the latest figures given.
A spokesman for the group said it had never had any dealings with Ansbacher Cayman.
He could not comment in relation to Mr Murphy.
In their report, the Ansbacher inspectors named Mr John Murphy as one of the people who had failed to assist them as required.
Mr Murphy's solicitors, in the course of correspondence, admitted that Mr Murphy established certain trusts, though not in Cayman, the inspectors noted.
They also admitted that these trusts did business with Ansbacher Cayman.
Because Mr Murphy would not co-operate with the Ansbacher inspectors, they were unable to conclude whether he was an Ansbacher client.
Guinness & Mahon London, and Investec Bank UK Ltd, were also deemed not to have co-operated with the inspectors.
