¶1 This is a suit in equity, brought by the complainants as creditors of the late firm of Samuel Rodman & Sons against the defendant, as assignee under an assignment of Samuel Rodman & Sons for the benefit of their creditors, for an account. The bill was answered by the defendant, and subsequently the case was referred to a master to take the account under a decree entered by consent, and stated to be so entered in the decree itself. The master has gone on under the decree and taken testimony, and now, while the cause is still pending before him, the complainants move for leave to amend the bill by adding allegations which, on the supposition that they show grounds for equitable relief, will if allowed make a substantially different case. The defendant opposes the motion. We do not think it can be granted while the case is in its present posture.
¶2 If the amendment were allowed and the defendant were to submit to it, without defending against it by plea, answer, or demurrer, and the bill as amended were to stand for further hearing before the master, then the result would be this, that the master would go on taking the account under a decree by consent in a case which was never referred to him by consent, and the record would belie itself. An amendment of the bill, by new and substantial allegations, without the defendant’s consent, makes the decree a decree in invitum just as effectually as if the decree itself was amended without his consent; and it is well settled that a consent decree cannot be materially altered without the consent of both parties to it. Edney v. Edney, 81 N. Car. 1; Leitch v. Cumpston, 4 Paige, 476; Rose v. Brown, 17 W. Va. 649; Manion v. Fahy, 11 W. Va. 482, 497. The fact that the master cannot go *357 on under the decree and consider tbe matters proposed to be introduced by tbe amendment shows conclusively that tbe alteration of, tbe bill will be in legal effect an alteration of tbe decree.
¶3 Undoubtedly, however, the defendant would not submit to tbe amendment without a plea, answer, or demurrer. An amendment, however trivial, and a fortiori such an amendment as is here proposed, authorizes the defendant to put in an answer making an entirely new defence contradicting his former answer. 1 Daniell Chanc. Pract. *409. If the amendment were allowed, with the case still before the master, and the amended bill were answered raising new issues of fact and law, as without doubt it would be, we should have the cause split in twain and proceeding in sections at once before the master and before the court. Manifestly this would be entirely contrary to the course of equity.
¶4 Motion dismissed.
