The making of a payment or the doing of an act under an obligation while reserving the right to object to the obligation at a later date. Typically, a party will make the payment or perform the act, but will at the same time inform the other party in writing that the performance is under protest. The statement “under protest,” “without prejudice,” “with reservation of right,” or the like will prevent anaccord and satisfaction and will prevent prejudice to the rights reserved. http://www.answers.com/topic/under-protest請問這題是從dr.eye 的例句出來的...
