Again its rather irrelevant to the thread but you're wrong in stating that PABs are composed of accountants. The board of CARB for example is by rule composed of a majority of non-accountant members.

The reason I mentioned accountants in the first instance is that an aggrieved member of the public has recourse to file a complaint, which much be handled and processed to IAASA standards, if they have a grievance arising from an engagement with an accredited Irish accounting firm. (They also have potential remedies in domestic civil law.) They have no guaranteed recourse if they choose to engage with an operator in an "exotic" ie cowboy location overseas.
Anyone would be foolish enough to do so would be laughed off the park if they sought the State to underwrite their losses or otherwise bail them out if things went wrong.
