MERCY.-Formerly when the judgment in an action was for the plaintiff, the defendant was said to "be in mercy" (misericordia), i. e. amerced or fined for his delay of justice; and when the judgment was for the defendant, the plaintiff was said to "be in mercy " for his false claim.

That operation of law which extinguishes a right by reason of its coinciding with another right, of greater legal worth, in the same person. By "operation of law" is meant that it may take place independently of the wishes or intention of the parties; and by "greater legal worth" is meant that one right in estimation of law, though not necessarily in fact, is of higher value than the other. 2. Rights of action. In the law relating to rights of action, when a person takes or acquires a remedy or security of a higher nature, in legal estimation, than the one which he already possesses for the same right, then his remedies in respect of the minor right or security merge in those attaching to the higher one. (Leake Cont. 506; Price v. Moulton, 10 Com. B. 561.) Thus, if a bond is taken for a simple contract debt, the remedy upon the simple contract is extinguished, and therefore an action for the debt must be brought on the bond; again, if judgment is recovered in such an action, the right of action on the bond is merged in the judgment, and therefore no second action can be brought on the bond.
