MR. JUSTICE WHITE delivered the opinion of the Court.The disputed issue here is whether a bankruptcy court has summary jurisdiction to order the surrender of voidable preferences asserted and proved by the trustee in response to a claim filed by the creditor who received the preferences.  The Court of Appeals held that the bankruptcy court had such summary jurisdiction.  336 F.2d 535.  We affirm.The corporate bankrupt began business on April 21, 1960, and borrowed $50,000 from two local banks.  Petitioner, then an officer of the company, was an accommodation maker on the two corporate notes delivered to the banks.  After the corporate bankrupt in this case suffered a disastrous fire, its funds and collections were placed in a "trust account" under the sole control of petitioner.  From this account petitioner made two payments on one of the company notes on which he was an accommodation maker and one payment on the other.  Bankruptcy followed within four months of these payments.  Petitioner filed two claims in the proceeding, one for rent due him from the bankrupt and one for a payment on one of the notes made from his personal funds.  The trustee responded with a petition asserting that the payments from the trust fund to the banks were voidable preferences and demanding judgment for the amount of the preferences, along with the amount of an unpaid stock subscription owed to the corporation by petitioner.  Petitioner's objection to the summary jurisdiction of the referee was overruled, and judgment was rendered for the trustee on both the preferences and the stock subscription.  Petitioner's claims were to be allowed only when and if the judgment was satisfied.  The District Court sustained the referee.  A divided Court of Appeals, sitting en banc, after reconsidering Inter-State National Bank of Kansas City v. Luther, 221 F.2d Page 382 U. S. 326 382 (C.A.10th Cir. 1955), cert. dismissed under Rule 60, 350 U.S. 944, adhered to its pronouncements in that case, affirmed the judgment for the amount of the voidable preferences but reversed the judgment for the amount of the stock subscription.  The trustee did not seek review here of the adverse decision on the stock subscription.  We granted certiorari on the creditor's petition because of the diversity of views among the Courts of Appeals on the issue involved [Footnote 1] and the importance of the question in the administration of the bankruptcy laws.  380 U.S. 971.The crux of the dispute here concerns the mode of procedure for trying out the preference issue.  The bankruptcy Page 382 U. S. 327 courts are expressly invested by statute with original jurisdiction to conduct proceedings under the Bankruptcy Act. [Footnote 2]  These courts are essentially courts of equity, Local Loan Co. v. Hunt, 292 U. S. 234,  292 U. S. 240; Pepper v. Litton, 308 U. S. 295,  308 U. S. 304, and they characteristically proceed in summary fashion to deal with the assets of the bankrupt they are administering.  The bankruptcy courts "have summary jurisdiction to adjudicate controversies relating to property over which they have actual or constructive possession."  Thompson v. Magnolia Petroleum Co., 309 U. S. 478,  309 U. S. 481; Cline v. Kaplan, 323 U. S. 97,  323 U. S. 98-99; May v. Henderson, 268 U. S. 111,  268 U. S. 115-116; Taubel-Scott-Kitzmiller Co. v. Fox, 264 U. S. 426,  264 U. S. 432-434.  They also deal in a summary way with"matters of an administrative character, including questions between the bankrupt and his creditors, which are presented in the ordinary course of the administration of the bankrupt's estate."Taylor v. Voss, 271 U. S. 176,  271 U. S. 181; United States Fidelity & Guaranty Co. v. Bray, 225 U. S. 205,  225 U. S. 218.  This is elementary bankruptcy law which petitioner does not dispute.But petitioner points out that, if a creditor who has received a preference does not file a claim in the bankruptcy proceeding and holds the property he received under a substantial adverse claim, so that the property may not be deemed within the actual or constructive possession of the bankruptcy court, the trustee may recover the preference only by a plenary action under § 60 of the Act, 11 U.S.C. § 96 (1964 ed.), See Taubel-Scott- Page 382 U. S. 328 Kitzmiller Co. v. Fox, 264 U. S. 426; and, in a plenary action in the federal courts, the creditor could demand a jury trial, Schoenthal v. Irving Trust Co., 287 U. S. 92,  287 U. S. 94-95; Adams v. Champion, 294 U. S. 231,  294 U. S. 234; compare Buffum v. Peter Barceloux Co., 289 U. S. 227,  289 U. S. 235-236.  Petitioner contends the situation is the same when the creditor files a claim and the trustee not only objects to allowance of the claim, but also demands surrender of the preference.  This is so, petitioner argues, because the Bankruptcy Act does not confer summary jurisdiction on a bankruptcy court to order preferences surrendered, and because, if it does, petitioner's rights under the Seventh Amendment of the Constitution are violated.  We agree with neither contention.With respect to the statutory question, it must be conceded that the Bankruptcy Act does not, in express terms, confer summary jurisdiction to order claimants to surrender preferences.  But Congress has often left the exact scope of summary proceedings in bankruptcy undefined, and this Court has elsewhere recognized that, in the absence of congressional definition, this is a matter to be determined by decisions of this Court after due consideration of the structure and purpose of the Bankruptcy Act as a whole, as well as the particular provisions of the Act brought in question.  Taubel-Scott-Kitzmiller Co. v. Fox, 264 U. S. 426,  264 U. S. 431 and n. 7.When Congress enacted general revisions of the bankruptcy laws in 1898 and 1938, it gave "special attention to the subject of making [the bankruptcy laws] inexpensive in [their] administration."  H.R.Rep. No. 1228, 54th Cong., 1st Sess., p. 2; H.R.Rep. No. 1409, 75th Cong., 1st Sess., p. 2; S.Rep. No. 1916, 75th Cong., 3d Sess., p. 2.  Moreover, this Court has long recognized that a chief purpose of the bankruptcy laws is "to secure a prompt and effectual administration and settlement of the estate of all bankrupts within a limited period," Ex Page 382 U. S. 329 parte Christy, 3 How. 292,  44 U. S. 312, and that provision for summary disposition, "without regard to usual modes of trial attended by some necessary delay," is one of the means chosen by Congress to effectuate that purpose, Bailey v. Glover, 21 Wall. 342,  88 U. S. 346.  See generally Wiswall v. Campbell, 93 U. S. 347,  93 U. S. 350-351; United States Fidelity & Guaranty Co. v. Bray, 225 U. S. 205,  225 U. S. 218.It is equally clear that the expressly granted power to "allow," "disallow" and "reconsider" claims, Bankruptcy Act, § 2a(2), 11 U.S.C. § 11a(2) (1964 ed.), [Footnote 3] which is of "basic importance in the administration of a bankruptcy estate," Gardner v. New Jersey, 329 U. S. 565,  329 U. S. 573, is to be exercised in summary proceedings, and not by the slower and more expensive processes of a plenary suit.  United States Fidelity & Guaranty Co. v. Bray, 225 U. S. 205,  225 U. S. 218,; Wiswall v. Campbell, 93 U. S. 347,  93 U. S. 350-351.  This power to allow or to disallow claims includes"full power to inquire into the validity of any alleged debt or obligation of the bankrupt upon which a demand or a claim against the estate is based.  This is essential to the performance of the duties imposed upon it."Lesser v. Gray, 236 U. S. 70,  236 U. S. 74.  The trustee is enjoined to examine all claims and to present his objections, Bankruptcy Act, § 47a(8), 11 U.S.C. § 75a(8) (1964 ed.), [Footnote 4] and "[w]hen objections are made, [the court] is duty-bound to pass on them," Gardner v. New Jersey, 329 U. S. 565,  329 U. S. 573.  "The whole process of proof, allowance, and distribution is, shortly speaking, an adjudication of interests claimed in a res," id. at  329 U. S. 574, and thus falls within the principle quoted above that bankruptcy courts Page 382 U. S. 330 have summary jurisdiction to adjudicate controversies relating to property within their possession.  Further, the Act itself directs that"[o]bjections to claims shall be heard and determined as soon as the convenience of the court and the best interests of the estates and the claimants will permit,"Bankruptcy Act, § 57(f), 11 U.S.C. § 93(f) (1964 ed.), and a committee report indicates that the provision means that "[o]bjections shall be heard and determined in a summary way," H.R.Rep. No. 1674, 52d Cong., 1st Sess., p. 20.Section 57 of the Act contains another important congressional directive around which much of this case turns.  Subsection g forbids the allowance of a claim when the creditor has "received of acquired preferences . . . void or voidable under this title" absent a surrender of any preference.  Bankruptcy Act, § 57(g), 11 U.S.C. § 93(g) (1964 ed.). [Footnote 5]  Unavoidably, and by the very terms of the Act, when a bankruptcy trustee presents a § 57(g) objection to a claim, the claim can neither be allowed nor disallowed until the preference matter is adjudicated.  The objection under § 57(g) is, like other objections, part and parcel of the allowance process, and is subject to summary adjudication by a bankruptcy court.  This is the plain import of § 57, and finds support in the same Page 382 U. S. 331 policy of expedition that underlies the necessity for summary action in many other proceedings under the Act.There is no contrary indication in any other provision of the Act.  The provisions of the Acts of 1800 and 1841 which gave the creditor the right to have his claim tried by a jury were not repeated in the Acts of 1867 and 1898. [Footnote 6]  Section 19 of the current law, Bankruptcy Act, § 19, 11 U.S.C. § 42 (1964 ed.), requires a jury in only limited situations, and is not helpful to petitioner in this case.  It is true that § 60, dealing with preferences and their voidability, confers concurrent jurisdiction on state courts and the federal bankruptcy courts to entertain plenary suits for the recovery of preferences.  But, by its own terms, this provision applies only "where plenary proceedings are necessary," and hence itself contemplates non-plenary recovery proceedings. [Footnote 7]If anything, the other provisions of the Act support the view that § 57(g), objections are to be summarily determined.  Section 57(k) provides for reconsideration of claims that have previously been allowed, and § 57(l) Page 382 U. S. 332 provides that, when a claim has been reconsidered and rejected, the trustee may recover any dividend previously paid on it, proceedings for such recovery to be within the summary jurisdiction of a bankruptcy court. [Footnote 8]  Even under the predecessor to the present section, which did not expressly provide that the dividend could be summarily recovered, Bankruptcy Act of 1898, § 57(1), 30 Stat. 561, this Court held that the referee had jurisdiction to determine whether a preference has been received and to order return of the dividend.  Pirie v. Chicago Title & Trust Co., 182 U. S. 438,  182 U. S. 455-456. [Footnote 9]  So Page 382 U. S. 333 too, proceedings under § 60(b), 11 U.S.C. § 96(d) (1964 ed.), [Footnote 10] for examination of the reasonableness of amounts paid in contemplation of bankruptcy to an attorney for services to be rendered for the bankrupt are within the summary jurisdiction of the referee, although the Act does not expressly so provide.  In re Wood and Henderson, 210 U. S. 246; Conrad, Rubin & Lesser v. Pender, 289 U. S. 472.So far,, we have been discussing principles applicable to a case where the trustee presents a § 57(g) objection to a claim but does not seek the affirmative relief of surrender of the preference.  But once it is established that the issue of preference may be summarily adjudicated absent an affirmative demand for surrender of the preference, Page 382 U. S. 334 it can hardly be doubted that there is also summary jurisdiction to order the return of the preference.  This is so because, in passing on a § 57(g) objection, a bankruptcy court must necessarily determine the amount of preference, if any, so as to ascertain whether the claimant, should he return the preference, has satisfied the condition imposed by § 57(g) on allowance of the claim.  Schwartz v. Levine & Malin, Ins., 111 F.2d 81 (C.A.2d Cir. 1940).  Thus, once a bankruptcy court has dealt with the preference issue, nothing remains for adjudication in a plenary suit.  The normal rules of res judicata and collateral estoppel apply to the decisions of bankruptcy courts.  Chicot County Drainage District v. Baxter State Bank, 308 U. S. 371,  308 U. S. 376-377; Stoll v. Gottlieb, 305 U. S. 165.  More specifically, a creditor who offers a proof of claim and demands its allowance is bound by what is judicially determined, Wiswall v. Campbell, 93 U. S. 347,  93 U. S. 351; and if his claim is rejected, its validity may not be relitigated in another proceeding on the claim.  Sampsell v. Imperial Paper Corp., 313 U. S. 215,  313 U. S. 218-219; Lesser v. Gray, 236 U. S. 70,  236 U. S. 75.  The Courts of Appeals have uniformly applied these principles to hold that a bankruptcy court's resolution of the § 57(g) objection is res judicata in a subsequent action by the trustee under § 60 to recover the preference.  Schwartz v. Levine & Malin, Inc., 111 F.2d 81 (C.A.2d Cir. 1940); Giffin v. Vought, 175 F.2d 186 (C.A.2d Cir. 1949); Ullman, Stern & Krausse v. Coppard, 246 F. 124 (C.A.5th Cir. 1917); Breit v. Moore, 220 F. 97 (C.A.9th Cir. 1915); Johnson v. Wilson, 118 F.2d 557 (C.A.9th Cir. 1941); see In re J. R. Palmenberg Sons, 76 F.2d 935 (C.A.2d Cir. 1935), aff'd sub nom. Bronx Brass Foundry, Inc. v. Irving Trust Co., 297 U. S. 230.  To require the trustee to commence a plenary action in such circumstances would be a meaningless gesture, and it is well within the equitable powers of the bankruptcy Page 382 U. S. 335 court to order return of the preference during the summary proceedings on allowance and disallowance of claims.  Compare In re Wood and Henderson, 210 U. S. 246,  210 U. S. 256 (determination of reasonableness of attorney's fee would be res judicata in suit to recover the excess), with Conrad, Rubin & Lesser v. Pender, 289 U. S. 472 (upholding turnover order).  What we said in Alexander v. Hillman, 296 U. S. 222, in connection with the jurisdiction of a receivership court to entertain a counterclaim against a claimant in the receivership proceeding, is equally applicable here:"By presenting their claims, respondents subjected themselves to all the consequences that attach to an appearance. . . .""*    *    *    *" "Respondents' contention means that, while invoking the court's jurisdiction to establish their right to participate in the distribution, they may deny its power to require them to account for what they misappropriated.  In behalf of creditors and stockholders, the receivers reasonably may insist that, before taking aught, respondents may by the receivership court be required to make restitution.  That requirement is in harmony with the rule generally followed by courts of equity that, having jurisdiction of the parties to controversies brought before them, they will decide all matters in dispute and decree complete relief."296 U.S. at  296 U. S. 241-242.Our examination of the structure and purpose of the Bankruptcy Act and the provisions dealing with allowance of claims therefore leads us to conclude, and we so hold, that the Act does confer summary jurisdiction to compel a claimant to surrender preferences that under § 57(g) would require disallowance of the claim. [Footnote 11]  A number Page 382 U. S. 336 of Courts of Appeals, including the court below, have reached similar results. [Footnote 12]Petitioner contends, however, that this reading of the statute violates his Seventh Amendment right to a jury trial.  But although petitioner might be entitled to a jury trial on the issue of preference if he presented no claim in the bankruptcy proceeding and awaited a federal plenary action by the trustee, Schoenthal v. Irving Trust Co., 287 U. S. 92, when the same issue arises as part of the process of allowance and disallowance of claims, it is triable in equity.  The Bankruptcy Act, passed pursuant to the power given to Congress by Art. I, § 8, of the Constitution to establish uniform laws on the subject of bankruptcy, converts the creditor's legal claim into an equitable claim to a pro rata share of the res. Gardner v. New Jersey, 329 U. S. 565,  329 U. S. 573-574, a share which can neither be determined nor allowed until the creditor disgorges the alleged voidable preference he has already received.  See Alexander v. Hillman, 296 U. S. 222,  296 U. S. 242.  As bankruptcy courts have summary jurisdiction to adjudicate controversies relating to property over which they have actual or constructive possession, Thompson v. Magnolia Petroleum Co., 309 U. S. 478,  309 U. S. 481; Cline v. Kaplan, 323 U. S. 97,  323 U. S. 98-99; May v. Henderson, 268 U. S. 111,  268 U. S. 115-116; and as the proceedings of bankruptcy courts are inherently proceedings in equity, Local Loan Co. v. Hunt, 292 U. S. 234,  292 U. S. 240; Pepper v. Litton, 308 U. S. 295,  308 U. S. 304; Page 382 U. S. 337 there is no Seventh Amendment right to a jury trial for determination of objections to claims, including § 57(g) objections.  As this Court has previously said in answering the argument that disputed claims must be tried before a jury:"But those who use this argument lose sight of the fundamental principle that the right of trial by jury, considered as an absolute right, does not extend to cases of equity jurisdiction.  If it be conceded or clearly shown that a case belongs to this class, the trial of questions involved in it belongs to the court itself, no matter what may be its importance or complexity.""*    *    *    *" "So, in cases of bankruptcy, many incidental questions arise in the course of administering the bankrupt estate which would ordinarily be pure cases at law, and, in respect of their facts, triable by jury, but, as belonging to the bankruptcy proceedings, they become cases over which the bankruptcy court, which acts as a court of equity, exercises exclusive control.  Thus, a claim of debt or damages against the bankrupt is investigated by chancery methods."Barton v. Barbour, 104 U. S. 126,  104 U. S. 133-134.  This has been the characteristic view of the courts.  Carter v. Lechty, 72 F.2d 320 (C.A.8th Cir. 1934); In re Michigan Brewing Co., 24 F. Supp. 430 (W.D.Mich.1938), aff'd, Conlon v. Michigan Brewing Co., 101 F.2d 1007 (C.A.6th Cir. 1939); In re Rude, 101 F. 805 (D.C.D.Ky.1900); In re Christensen, 101 F. 243 (D.C.N.D.Iowa 1900).  See also In re Wood and Henderson, 210 U. S. 246,  210 U. S. 258; Pirie v. Chicago Title & Trust Co., 182 U. S. 438,  182 U. S. 455-456.And, of course, it makes no difference, so far as petitioner's Seventh Amendment claim is concerned, whether the bankruptcy trustee urges only a § 57(g) objection Page 382 U. S. 338 or also seeks affirmative relief.  In practical effect, the denial of a jury trial would be no less were the bankruptcy court merely to determine the existence and amount of the preference, since that determination would be entitled to res judicata effect in any subsequent plenary action.  And we have held that equity courts have power to decree complete relief, and, for that purpose, may accord what would otherwise be legal remedies.  See Mitchell v. Robert DeMario Jewelry, Inc., 361 U. S. 288,  361 U. S. 291-292; Porter v. Warner Co., 328 U. S. 395,  328 U. S. 398-399; Alexander v. Hillman, 296 U. S. 222; McGowan v. Parish, 237 U. S. 285,  237 U. S. 296.Petitioner's final reliance is on the doctrine of Beacon Theatres, Inc. v. Westover, 359 U. S. 500, and Dairy Queen, Inc. v. Wood, 369 U. S. 469, that,"where both legal and equitable issues are presented in a single case, 'only under the most imperative circumstances, circumstances which, in view of the flexible procedures of the Federal Rules, we cannot now anticipate, can the right to a jury trial of legal issues be lost through prior determination of equitable claims."369 U.S. at  369 U. S. 472-473.The argument here is that the same issues -- whether the creditor has received a preference, and, if so, its amount -- may be presented either as equitable issues in the bankruptcy court or as legal issues in a plenary suit, and that the bankruptcy court should stay its own proceedings and direct the bankruptcy trustee to commence a plenary suit so as to preserve petitioner's right to a jury trial.  Unquestionably, the bankruptcy court would have power to give such an instruction to the trustee, Thompson v. Magnolia Petroleum Co., 309 U. S. 478,  309 U. S. 483-484; see Bankruptcy Act, § 2a(7), 11 U.S.C. § 11a(7) (1964 ed.), and some lower courts have required such a procedure, B. F. Avery & Sons Co. v. Davis, 192 F.2d 255 (C.A.5th Cir. 1951), cert. denied, 342 U.S. 945; Page 382 U. S. 339 Triangle Electric Co. v. Foutch, 40 F.2d 353, (C.A.8th Cir. 1930); see Katchen v. Landy, 336 F.2d 535, 543 (C.A.10th Cir. 1964) (Phillips, J., dissenting in part).  Nevertheless, we think this argument must be rejected.At the outset, we note that the Dairy Queen doctrine, if applicable at all, is applicable whether or not the trustee seeks affirmative relief.  For, as we have said, determination of the preference issues in the equitable proceeding would in any case render unnecessary a trial in the plenary action, because of the res judicata effect to which that determination would be entitled.  Thus, petitioner's argument would require that, in every case where a § 57(g) objection is interposed and a jury trial is demanded, the proceedings on allowance of claims must be suspended and a plenary suit initiated, with all the delay and expense that course would entail.  Such a result is not consistent with the equitable purposes of the Bankruptcy Act, nor with the rule of Beacon Theatres and Dairy Queen, which is itself an equitable doctrine, Beacon Theatres v. Westover, 359 U.S. at  359 U. S. 509-510.  In neither Beacon Theatres nor Dairy Queen was there involved a specific statutory scheme contemplating the prompt trial of a disputed claim without the intervention of a jury.  We think Congress intended the trustee's § 57(g) objection to be summarily determined; and to say that, because the trustee could bring an independent suit against the creditor to recover his voidable preference, he is not entitled to have his statutory objection to the claim tried in the bankruptcy court in the normal manner is to dismember a scheme which Congress has prescribed.  See Alexander v. Hillman, 296 U. S. 222,  296 U. S. 243.  Both Beacon Theatres and Dairy Queen recognize that there might be situations in which the Court could proceed to resolve the equitable claim first even though the results might be dispositive of the issues involved in Page 382 U. S. 340 the legal claim.  To implement congressional intent, we think it essential to hold that the bankruptcy court may summarily adjudicate the § 57(g) objection; and, as we have held above, the power to adjudicate the objection carries with it the power to order surrender of the preference.Affirmed
U.S. Supreme CourtKatchen v. Landy, 382 U.S. 323 (1966)Katchen v. LandyNo. 28Argued November 8, 1965Decided January 17, 1966382 U.S. 323SyllabusPetitioner, a corporate officer, was an accommodation maker on notes of the corporation to two banks.  After the corporation suffered a serious fire, its funds and collections were placed in a trust account under petitioner's control.  Petitioner made payments on the notes from this account within four months of the bankruptcy of the corporation.  Two claims were filed by petitioner in the bankruptcy proceeding, one for rent due him and one for a payment on one of the notes from his personal funds.  The trustee asserted that the payments from the trust fund to the banks were voidable preferences and demanded judgment for the amount of the preferences.  The referee overruled petitioner's objection to his summary jurisdiction and rendered judgment for the trustee on the preferences.  The District Court sustained the referee, and the Court of Appeals affirmed the judgment for the amount of the preferences.Held:  A bankruptcy court has summary jurisdiction to order the surrender of voidable preferences asserted and proved by the trustee in response to a claim filed by the creditor who received the preferences.  Pp.  382 U. S. 327-340.(a) While the Bankruptcy Act does not expressly confer summary jurisdiction to order claimants to surrender preferences, the scope of summary proceedings is determined by consideration of the structure and purpose of the Act as a whole and the particular provisions of the Act in question.  P.  382 U.S. 328.(b) Summary disposition is one of the means chosen by the Congress to effectuate its purpose of securing prompt settlement of bankrupt estates.  Pp.  382 U.S. 328-329.(c) The basically important power granted by § 2a(2) of the Act to "allow," "disallow" and "reconsider" claims is to be exercised in summary proceedings and not by the slower and more expensive process of a plenary suit.  Pp.  382 U.S. 329-330.(d) The trustee's objections under § 57g of the Act, which forbids allowance of a claim to a creditor who has received preferences Page 382 U. S. 324 "void or voidable under this title" without surrender of the preferences, is part of the allowance process, and is subject to summary adjudication by a bankruptcy court.  Pp.  382 U. S. 330-331.(e) Section 60 of the Act, which deals with preferences and their voidability and confers concurrent jurisdiction on state courts and federal bankruptcy courts to entertain plenary suits to recover preferences, applies only "where plenary suits are necessary," and thus contemplates nonplenary recovery proceedings.  P.  382 U. S. 331.(f) Since summary jurisdiction is available to determine the issue of preference absent a demand for surrender of the preference, it is also available to order return of the preference.  This follows because a bankruptcy court, in passing on a trustee's § 57g objection, must determine the amount of preference, if any, so as to ascertain whether the claimant, should he return the preference, has satisfied the condition imposed by § 57g on allowance of the claim.  Pp.  382 U. S. 333-334.(g) When a bankruptcy court has dealt with the preference issue under its equity power, nothing remains for adjudication in a plenary suit, as the normal rules of res judicata and collateral estoppel apply.  P.  382 U. S. 334(h) Although petitioner might be entitled to a jury trial on the preference issue if he presented no claim in the bankruptcy proceeding and awaited plenary suit by the trustee, he is not so entitled when the issue arises as part of the processing of claims in bankruptcy proceedings, triable in equity.  Pp.  382 U. S. 336-337.(i) The doctrine of Beacon Theatres v. Westover, 359 U. S. 500, and Dairy Queen v. Wood, 369 U. S. 469, that"where both legal and equitable issues are presented in a single case, 'only under the most imperative circumstances . . . can the right to a jury trial of legal issues be lost through prior determination of equitable claims,'"is not applicable here where there is a specific statutory scheme providing for the prompt trial of disputed claims without a jury.  Pp.  382 U. S. 338-340.336 F.2d 535, affirmed. Page 382 U. S. 325
