The sum was paid ex gratia.

这是所付的一笔特惠款。

Another situation is linked to price High, said, "ex gratia" is not "ex-gratia. "

还有一种情况是挂价虚高，说“特惠”实不“特惠”。

An ex-gratia payment will only be made where we are satisfied that the original decision was wrong and a review application was unnecessary.

如果原始的决定是错的，同时复查申请是没有必要的地方才要求增加付费。
