Mr Fustok had previously bought a yearling horse from the then Taoiseach Charles Haughey for IR£50,000.The Tribunal considered that "The explanation advanced for the payment, namely that it was in consideration for the purchase of a yearling, is highly unconvincing and improbable".
This has remained the description up to present time, with current Irish passports describing the holder as a "citizen of Ireland" on the request page and giving the holder's nationality as "Éireannach/Irish" on the information page.
The matter was revealed during the Mahon Tribunal hearings in 2008; Mr Ahern commented that Mr Turner had an Irish mother, and that in 2007 some 7,000 other passport applications were assisted in some way by politicians.
The 2006 Moriarty Tribunal report covered the grant of passports to a Mr Fustok and some of his friends.
In the memorandum, the Secretary of State reported that "hitherto [the passports] (which have not, I understand, been amended since 1936 have borne two indications of relationship to the British Commonwealth of Nations".
These, the memorandum noted, were the reference to the King including his full title in the "request" page; and a front page, where underneath the words "Irish Free State" (in Irish, English and French) appear the words "British Commonwealth of Nations".
At the time dominion status was a limited form of independence and while the Constitution of the Irish Free State referred to citizens of the Free State, the rights and obligations of such citizens were expressed to apply only "within the limits of the jurisdiction of the Irish Free State". It insisted that the appropriate description was "British subject", because, inter alia, the Irish Free State was part of the British Commonwealth.
