COFFIN, Chief Judge,

Appellant began his long and arduous relationship with the Alien Property Custodian and the federal judicial system in the year 1941.1 Since that time his case has been scrutinized by judges and administrators at epic length. It falls to us to decide whether he has received the consideration which is his due or whether another round of judicial examination is called for. We hold that review of the administrative decision under Section 32 of the Trading with the Enemy Act (the Act), 50 U.S.C.App. 1 et seq. is foreclosed to the appellant; the district court properly dismissed the complaint.

Through all these years appellant's objective has been to recoup the value of seized items which included six packages of diamonds and two hundred seventy packages of synthetic and semi-precious stones, sold by the Alien Property Custodian, sometime subsequent to their vesting in 1945, for well over one million dollars.2

The history of appellant's business transactions is complex. It is set forth in Von Clemm v. Smith, 255 F. Supp. 353 (1965). For our purposes it is sufficient to note that, in 1938, appellant, an American citizen born in Germany, undertook to import jewels and other items from Europe under the corporate name Pioneer. He made partial payment in blocked marks which could be obtained at a discount. This commercial enterprise was potentially limited by the Presidential freezing orders of April and May 1940. Executive Order 8389 regulated trade with countries which had been overrun by German armed forces including Denmark, Norway and the Low Countries. Appellant's trade in Belgian and Dutch diamonds was threatened, but, without obtaining the requisite treasury licenses, he arranged a complicated subterfuge for importing the diamonds through Germany. There was persuasive evidence that these transactions, prior to the outbreak of war, involved close contact with and approval by the German government, and indeed that they were for the benefit of that government. See 255 F. Supp. at 362-363. One of the diamond shipments, arranged through intermediaries, cleared customs. This transaction led to appellant's prosecution and conviction for conspiracy to import under a false declaration that the diamonds were of German origin, in violation of the freezing orders and therefore of the Act, and of 12 U.S.C. 95, affirmed in United States v. Von Clemm, 136 F.2d 968 (2d Cir.), cert. denied, 320 U.S. 769, 64 S. Ct. 81, 88 L. Ed. 459 (1943). Other shipments similarly arranged were seized by customs and are the crux of this suit.

Upon the finding by the Custodian that the property was owned beneficially or directly be enemy nationals, the property was seized and vested as authorized by the Trading with the Enemy Act, 50 U.S.C.App. 5. The Act itself established the means to appeal such a determination. The routes provided for appeal are alternative routes. One or the other (but not both) is available to each claimant.3 Section 9(a) of the Act provides that anyone not an 'enemy' as defined therein may seek administrative return of the property and sue in equity in a federal district court. Section 32(a) indicates that for those ineligible for Section 9(a) relief there is exclusive administrative recourse.4

In 1959, after a denial of return of proceeds by a hearing examiner for the Office of Alien Property, appellant filed suit for return of the property under Section 9(a).5 The statutory scheme implicitly requires that the court determine de novo controverted issues. The liminal issue, upon which appellant's right to 9(a) relief depended was whether or not he was an 'enemy' or an 'ally of an enemy' under the Act.6 The district court held a six week trial, directed, in part, toward resolution of this dispute. Appellant was affirmatively shown to have been an agent of the German government until the outbreak of hostilities. The court concluded that in light of his prior conduct, and, in its view, appellant's failure to show that he had discontinued his relationship with the German government after the outbreak of war, he had failed to prove that he was not an agent of an enemy for purposes of the Act.7 Under 9(a) recourse to judicial remedy is limited to those not 'enemies' or 'allies of an enemy'. The court, therefore, dismissed the action for want of jurisdiction. Von Clemm v. Smith, 255 F. Supp. 353 (S.D.N.Y.1965), aff'd, 363 F.2d 19 (2d Cir. 1966), cert. denied, 385 U.S. 975, 87 S. Ct. 502, 17 L. Ed. 2d 438 (1966).

Appellant then pursued the route left open to those not qualified for 9(a) relief. He pursued administrative appeals until March 22, 1971 when the Attorney General issued an order disallowing the claim as 'not in the interest of the United States'. Within the meaning of 32(a)(5) of the Act, this last avenue led appellant to this court where he seeks to appeal the administrator's determination. The district court dismissed the complaint for want of subject matter jurisdiction. The court reasoned that Section 7(c) of the Act8 limits judicial review to claims filed pursuant to Section 9(a). Since, by judicial decision, appellant was eligible only for 32(a) relief, he had no basis for seeking judicial review of the exclusive administrative determination. The finality and exclusivity of administrative relief provided by Section 32(a) has been confirmed in Schilling v. Rogers, 363 U.S. 666, 80 S. Ct. 1288, 4 L. Ed. 2d 1478 (1960), which held this limitation on judicial review to be constitutional.9

Appellant argues that Schilling dealt only with the rights of enemy nationals, not entitled to Fifth Amendment protections. As a citizen, appellant claims that his right to an adjudication of his property rights cannot be diminished by imposing on him the burden of proving that he was not an 'ally of an enemy' under 9(a), or denied entirely through unreviewable administrative action, under 32(a). Having been subjected to the 'impermissible burden' in his earlier 9(a) court suit, he claims that a judicial forum for consideration of his constitutional claim must lie in review of the 32(a) determination.

Past Court pronouncements may perhaps be read as giving a constitutional bill of health to 9(a) by approving the availability to a nonenemy claimant of a later judicial hearing on the propriety of a seizure. See, e.g., Societe Internationale v. Rogers, 357 U.S. 197, 211, 78 S. Ct. 1087, 2 L. Ed. 2d 1255 (1958); Stoehr v. Wallace, 255 U.S. 239, 245-246, 41 S. Ct. 293, 65 L. Ed. 604 (1921). But in none of such cases were the status of the claimant and the claimant's burden to establish his nonenemy status in issue.

Assuming, without conceding, that appellant's claim is not foreclosed by prior cases, we examine it. Since Congress has demonstrated its intent to foreclose judicial review of the administrative decision under 32(a), a holding that such review is constitutionally required would have to be predicated on a finding that the present statutory scheme is fatally defective. Appellant claims that the taking of his property must be accompanied by the highest due process safeguard, judicial process. The most extensive judicial scrutiny includes determination of 'jurisdictional' or 'constitutional facts'.10 Here the essential fact is whether appellant was an 'enemy' or 'ally of an enemy' under the Act. Section 9(a) provides not only for judicial determination of this fact but a de novo judicial hearing. Appellant had the explicit opportunity to establish his status. He had the implicit opportunity to challenge the constitutionality of the burden of proof. The fact that judicial relief was made available before rather than after administrative jurisdiction was assumed is not determinative. See Yakus v. United States, 321 U.S. 414, 64 S. Ct. 660, 88 L. Ed. 834 (1944). 'There isn't often a constitutional right to a second bite at the apple.' The Power of Congress to Limit the Jurisdiction of the Federal Courts, 66 Harv.L.Rev. at 1369. The scheme itself provides all the requisite constitutional safeguards. That opportunity was not earlier seized to obtain a judicial ruling on appellant's constitutional assault on the proper burden of proof under 9(a) does not provide any basis for avoiding the ruling in Schilling that 32(a) relief is exclusively administrative and judicial review is foreclosed. The court below therefore properly ruled that it was without subject matter jurisdiction to review the claim.

We too are without jurisdiction to determine whether the district court in the Section 9(a) suit improperly required Von Clemm to bear an affirmative burden of proof.11 We note, however, that even if we had jurisdiction to consider its legal merits, appellant's claim, since it could have been presented to the second circuit on appeal from Von Clemm v. Smith, supra, would be barred by res judicata. The Court's statement a century ago is valid today:

'Judgment, rendered upon the merits, constitutes an absolute bar to subsequent action. It is a finality . . . concluding parties . . . not only as to every matter which was offered and received to sustain or defeat the claim . . . but as to any other admissible matter which might have been offered . . . Such demand or claim, having passed into judgment, cannot again be brought into litigation between the parties in proceedings at law upon any ground whatever.' Cromwell v. County of Sac, 94 U.S. 351, 352-353, 24 L. Ed. 195 (1876).

The policies underlying the doctrine are well illustrated by this case. At some point litigation must terminate.

The order of the District Court is affirmed.
