delivered the opinion of the Court.
J. R. ■Palmenberg Sons, Inc., was adjudged bankrupt-in the federal court for southern New, York in August, 1933. In September, Bronx Brass Foundry, Inc., filed its proof of claim. In January, 1934, the Irving Trust Company, trustee in bankruptcy, moved to expunge the claim on the ground that the creditor had received within the four months preceding the bankruptcy, payments on ac *231 count aggregating $1,000 which were unlawful preferences. The creditor denied the allegations of preference.
‘ On the issue thus raised, several hearings were had before the referee and the evidence introduced clearly indicated that the payments would, upon bankruptcy, effect a preference over other creditors of the same class, and that the claimant had received them having reasonable cause to believe the debtor insolvent. But it left uncertain whether the amount received was more than its pro rata share would have been, if the then existing assets had been ratably distributed among all the then creditors. Before the.hearing closed, and in view of an adverse ruling on the admission of evidence, the creditor filed a withdrawal of its claim and left the hearing.
The trustee objected to allowance of the withdrawal, and introduced further evidence, insisting that it was entitled to an adjudication of the question whether the payments made were unlawful preferences. The referee, at the close of the hearing, ordered that the claim be expunged, unless the creditor within 20 days repay the preference to the trustee, with interest from the date of service of the motion to'expunge. He said:
“When a creditor files a claim against the bankrupt estate he elects a forum which may hear and determine, whether a preference to him was made. Although judgment of recovery may not be granted, the finding thereon, subject to review, is conclusive as between the parties. It is not intended that a party shall have two trials of the same issue or be permitted to present the same issue to different tribunals for determination. When issue is joined upon, the question whether a voidable preference has been received, the creditor may not withdraw of his own motion and thereby avoid such determination as the proof warrants.”
The District Court approved the order of the referee. Its judgment was affirmed by the Circuit Court of Ap
*232
peals, which held that the creditor had received a preference although the proof did not show that at the times of the payments the assets of the-debtor were insufficient to pay proportional amounts to all the other creditors, 76 E. (2d) 935. We granted certiorari, because the ruling on the right of the creditor to withdraw its claim appeared to conflict with
Scholl Mfg. Co.
v.
Rodgers,
51 F. (2d) 971, decided by the Court of Appeals for the Eighth Circuit; and because the ruling on the question of preference conflicted with
W. S. Peck & Co. v. Whitmer,
First.
The referee was justified in refusing to permit the creditor to withdraw its claim. The Circuit Court of Appeals recognized that ordinarily a plaintiff in equity has, as stated in
