delivered the opinion of the court.
The trustee in bankruptcy of the St. Louis Chemical Company brought suit in a state court of Michigan against the Gratiot County State Bank to recover, as ¿Ilegal preferences, payments made to it within four months before the filing of the involuntary petition. The Bank denied the allegation that the Chemieal Company was. insolvent when the payments wére made. To establish that fact, the Trustee offered in evidence the adjudication together with the petition on which.it was based and the special master’s report which it confirmed. Thé latter found
*248
that the debtor had been insolvent for four months or more before the filing of the petition and had made, While so insolvent, certain preferences. The Bank was not actually a party to the bankruptcy proceedings ánd had taken no part therein. The trial court held that this evidence was not only admissible but established conclusively that the debtor was insolvent throughout the four months; and it entered judgment for the Trustee which was affirmed by the Supreme Court of Michigan (193 Michigan, 452). The case comes here on writ of certiorari (
First.
The Trustee contends that adjudication in bankruptcy, being in the nature of a judgment
in rem,
establishes not only the status of the debtor as a bankrupt, but also the essentia! findings of fact bn which that judgment was based. The adjudication is, for the purpose of administering the debtor’s property, that is, in its legislative effect, conclusive upon all the world. Compare
Shawhan
v.
Wherritt,
Second.
The Trustee contends, however, that since by §§ 185 and-59f
1
of the Bankruptcy Act, any creditor is entitled to intervene in the bankruptcy proceedings, the Bank should be considered a party thereto. These sections are permissive, not mandatory. They give to a creditor, who fears that he will be prejudiced by an adjudication of bankruptcy, the right to contest the petition. Whether he does so or not, he will be bound, like the rest of the world, by the judgment, so far as it is strictly an adjudication of bankruptcy. But he is under no obligation to intervene, and the existence of the fight is not equivalent to actual intervention. Unless he exercises the right to become a party, he remains a stranger to the litigation and, as such, unaffected by the decision of even essential subsidiary issues.
In re McCrum,
214 Fed. Rep. 207, 213;
Cullinane
v.
Bank,
The purpose of Congress in expressly authorizing creditors, as well as the debtor, to answer an involuntary petition in bankruptcy was to guard against an improvident adjudication and to protect those whose peculiar interests might be prejudiced by establishing the status of bankruptcy. See Blackstone v. Everybody's Store, 207 Fed. Rep. 752, 756; Jackson v. Wauchula Mfg. & Timber Co., 230 Fed. Rep. 409, 411. The grant of this right of intervention was harmonized with the general purpose of Congress to secure a prompt adjudication, by requiring that the appéarance and answers of creditors be made within five days after the return day on the petition. Had the adjudication been made determinative also of claims of the several creditors'against the estate or of claims of the estate against individual creditors, such expedition in proceedings would be impossible, if each of the many widely scattered creditors is to be afforded a fair opportunity to be heard. Furthermore, to require every creditor to acquaint himself with the issues raised in every proceeding in bankruptcy against his debtors, in order to determine whether a decision on any such issue might conceivably affect his interests; and, if so, either to participate in the litigation, or, at his peril, suffer the decision of every question therein litigated to become res judicata as against him, would be an intolerable hardship upon creditors. And the resulting volume of litigation would often so delay the adjudication as to defeat the purposes of the Bankruptcy Act.
*251
The unreasonableness of the rule contended for by the Trustee is well illustrated in cases of alleged fraudulent preference. The claim may be made in respect to any creditor paid off within four months of the filing of an involuntary petition,' that he received a fraudulent preference. Is every such former creditor to .be deemed an existing creditor within the meaning of §§ 186 and 59/ and a party to the bankruptcy proceeding? Compare
Keppel
v.
Tiffin Savings Bank,
The decisions of the lower federal courts upon which the state court relied 1 in holding that §§ 186 and 59/ made all creditors parties to the proceeding so as to render. *252 the adjudication binding on them as to all essential issues, clearly misconceived the intention of Congress. The allegation in the involuntary petition that the Bank was among those who had received preferences, did not impose upon it the duty to appear and answer; and since it did not do so, even a finding to that effect by the bankruptcy court would not have bound it. The Supreme Court of Michigan eired in holding that the adjudication in bankruptcy established- conclusively as against the Bank that the debtor was insolvent at the time the payments were made. We have no occasion to consider whether the record introduced was admissible merely as evidence of insolvency.
