DE-MUR'RER, n.

1. One who demurs.
2. In law, a stop at some point in the pleadings, and a resting of the decision of the cause on that point; an issue on matter of law. A demurrer confesses the fact or facts to be true, but denies the sufficiency of the facts in point of law to support the claim or defense. A demurrer may be tendered to the declaration, to the plea, to the replication, to the rejoinder, &c. – Blackstone.
