Well good luck in convincing the U.S. authorities that an out of court settlement constitutes corruption. Happens all the time, but especially in corporate America. All perfectly legal.
While probably fully legal, I think it's a dangerous road taken to "reimburse" a country for a refereeing mistake.
FIFA might as well start dishing out near miss payments to all countries that narrowly misses qualification because most of them will be able to find refereeing decisions that went against them at crucial times, obviously less grave than Henry's handball.
That depends on the legal merits of the case in question. The Irish clearly had a case, or an out of court settlement wouldn't have arisen.
The dangerous road isn't the making of an out of court settlement, it's that refereeing mistakes would appear to be legitimately open to legal challenge.
And as for the rubbish spouted by the Telegraph, what would they have done? Proceeded with a legal challenge? Whose best outcome would have been...to award the Irish FA cash damages!
