We ordered the parties to this appeal from the dismissal of a third-party claim to brief several issues relating both to our jurisdiction and to that of the district court before the merits of the appeal are briefed and argued. We conclude that we have jurisdiction but that the district court did not, at least with respect to the receiver’s claim. We vacate the judgment and direct the district court to dismiss that claim and tо reconsider its action in allowing a number of individual investors to join as third-party co-plaintiffs with the receiver.
The Commodity Futures Trading Commission brought suit against John Tobin, a trader who is alleged to have defrauded investors оf more than $1 million, for violations of the Commodities Exchange Act. At the Commission’s request, the district court appointed an equity receiver for Tobin. The assigned task of the receiver (John Troelstrup) was to identify, tаke possession of, marshal, and administer Tobin’s assets, so that they would be available to persons having claims against Tobin, primarily the defrauded investors. See 28 U.S.C. § 959(b); Fed.R.Civ.P. 66; 12 Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 2981 (1973). The receiver filed a third-party claim, in the Commission’s suit, against Index Futures Group, Inc. and an affiliated company that we can ignore. Index is a registered futures commission merchant through which Tobin traded, and the claim is *1276 that its negligence facilitated Tоbin’s fraud. This claim was filed on behalf not of Tobin as such, for he had not been wronged by Index’s negligence, but of four commodities trading accounts (later reduced to one, the title of which was “Phoenix Pharynol”) that Tobin had established with Index. Later the district judge allowed the receiver’s lawyer to amend the complaint to add as coplaintiffs 57 individuals whose money Tobin had put into the Phoenix Pharynol account. After a bench trial the district judge gave judgment for the third-party defendant, Index. The receiver and the individual investors have appealed.
The investor appellants designated the wrong order in their notice of appeаl, but this mistake, not having misled anyone, is not fatal.
Foman v. Davis,
Where, as in a cаse such as this, the challenge is to an order placing certain assets beyond the receiver’s reach, so that an appeal from the order would not place the receiver in conflict with the duty the court had laid upon him of maximizing the value of the debtor’s (that is, of Tobin’s) estate, the court can be expected to permit the appeal. Indeed in this case the district judge issued a “clarification,” after the appeal was filed, indicating that he had intended to allow the receiver to appeal all along. No formalities are prescribed for authorizing an appeal by a recеiver, so we do not think the belatedness of the permission in this case is a bar to our jurisdiction — especially as it is far from clear that the requirement of permission should be deemed jurisdictional.
The practical consequence of deeming the issue jurisdictional would be that we would have to dismiss the appeal even if neither party was objecting to our deciding it. Issues thus are treated as jurisdictional when the Constitution, statutes, or rules evince a purpose to limit judicial power whether or not a party objects to its exercise. It is difficult to see the judge-made rule about getting the receiver’s permission to apрeal in this light. Not all rules regulating appellate jurisdiction are deemed jurisdictional. The civil rules require that a final judgment be set forth on a separate document from the court’s opinion, Fed.R.Civ.P.
*1277
58, but noneomplianee with the rule does not prevent the judgment from being treated as final and so appealable. E.g.,
Bankers Trust Co. v. Mollis,
The district court’s jurisdiction over the third-party claim is also secure. Even though the claim was filed before the effective date of the statute creating the supplemental jurisdiction of the federаl district courts, 28 U.S.C. § 1367, it is not barred by
Finley v. United States,
Scholes
also makes clear, however, that the receiver did not have standing to sue “on behalf of’ the Phoenix Pharynol account (meaning, as a practical matter, on behalf of the investors whose investments were deposited in that account), even though the account was an instrumentality of Tobin’s fraud. In
Scholes,
the Tobin figure had created corporations that in turn created the limited partnerships in which the defrauded investors had put their money. The Tobin counterpart had then caused the corporations to divert that money to him, his ex-wife, his favorite charities, and so on. We held that his receiver,
who had also been appointed the corporations’ receiver,
had stаnding to sue on behalf of the corporations, because they were entitled to the return of the money that the defrauder had improperly diverted from them. Troelstrup was not appointed receiver for Phoenix Pharynol as well as Tobin. He was appointed as receiver for Tobin both in his own name, and
doing business as
Phoenix Pharynol and the other accounts now consolidated with it, which is like saying that he was appointеd as receiver for Tobin both under Tobin’s real name and under various aliases. Troelstrup, thus, was just Tobin’s receiver, and so he could not sue Index on behalf of Phoenix Pharynol, not having been appointed its reсeiver. And he could not sue Index on behalf of either Tobin, the defrauder, who has no possible claim against Index, or on behalf of the investors, the victims of the fraud, because he was not
their
receiver.
Scholes v. Lehmann, supra,
Not only was Troelstrup not appointed the receiver of anyone except Tobin; he сould not have been appointed the receiver of Phoenix Pharynol because it is not a corporation or other legally recognized entity on whose behalf a receiver or anyone else could sue. In
Scholes
there were entities that might be bearers of legal rights, besides the defrauder, and so the receiver wasn’t limited to being a receiver for the defrauder. All there is here, besides Tobin himself, is an aсcount in a brokerage house. The account is an asset, like a bank account, rather than a rights-bearing entity. It was established by Tobin as a sole proprietorship, which is a type of enterprise that, аs we observed recently, has no legal identity apart from the proprietor.
Bartlett v. Heibl,
This leaves the 57 investor coрlaintiffs to be considered. The district judge, so far as we can reconstruct from a sketchy record, allowed them to be added to the case by amendment on the ground that their claims were ancillary to thе receiver’s third-party claim. That to which they are ancillary was never within the district court’s jurisdiction. Whether they may file their own third-party claim against Index in the CFTC’s suit is a matter to be considered in the first instance by the district сourt. The judgment is vacated with directions to that court to dismiss the receiver’s claim against Index and to reconsider the grant of leave to amend the complaint to add the individual investors as co-plaintiffs.
VACATED AND REMANDED WITH DIRECTIONS.
