OPINION OF THE COURT
Edwаrd D. Carucci and five co-defendants, Anthony P. DiGiacomo, Michael J. Pepe, Thomas Alfred Capodanno, Michael Niland and Eugene Papaleo, were tried in the United States District Court for the District of Delaware under a two-count indictment charging them in the first count with violating the federal gambling statute, 18 U.S.C. § 1955, 1 and in the second count with conspiring to violate that statute, 18 U.S.C. § 371. The first count of the indictment was dismissed on the Government’s motion. Mr. Pepe pleaded guilty to the second count, but the remaining five defendants, having wаived a jury, were tried to the Court. Pursuant to Federal Rule of Criminal Procedure 23(c), 2 the District Court entered specific findings of faсt and law under which Messrs. Capodanno and Papaleo were acquitted and Messrs. DiGiacomo, Niland and Carucci werе found guilty of conspiring to operate a gambling business which, inter alia, involved five or more participants. 3
*1136 Messrs. DiGiacomo and Carucci filed timely appeals. Mr. Carucci argued that, although he was admittedly a participant in gambling activities, it was error to convict him because he neither expected nor received economic gain or other compensation for his participation.
Mr. DiGiacоmo, in his appeal, took the position that his conviction could not be sustained because the Government failed tо prove beyond a reasonable doubt that the object of the conspiracy was a federal offense. Morе specifically, Mr. DiGiacomo argued to another panel 4 of this court that the evidence presented at trial fаiled to show that he anticipated or reasonably should have expected that five persons were involved in the underlying gambling operation. Mr. DiGiacomo’s conviction was reversed, the panel concluding that the evidence at trial еstablished only that four persons (not the five required by § 1955) were involved in the gambling business and, therefore, no conspiracy to violаte § 1955 existed. It was reasoned that
. to convict a defendant of conspiracy to violate § 1955, it is incumbent upon the Govеrnment to prove an agreement which contemplates the commission of a crime and that such crime is in fact and lаw a federal offense. As such, the overall objective of the conspiracy agreed to must encompass, inter alia, an intention or understanding that five or more persons will be involved in an illegal gambling operation. 5
Although Mr. Carucci has not raised the issue of the Government’s failure to prove the requisite number of participants in the underlying offense, his conviction, like that of Mr. DiGiаcomo, was predicated upon the District Court’s finding that a fifth unnamed individual participated in the gambling operation. Spеcifically, in its Findings of Fact No. 8 and No. 29, respectively, the District Court concluded:
From at least the end of 1971 to May of 1972 there wеre five or more persons who participated in conducting the gambling business headed by Michael Pepe. In addtion to Miсhael Pepe and his line source, Michael Ni-land, Anthony DiGiacomo and Edward Carucci participated by conducting bookmaking opеrations which regularly and continuously supplied the Pepe book with substantial lay-off wagers, [emphasis added]
During that period, Mr. Carucci was aware of the participation of at least the following individuals in the Pepe gambling business: himself, Michael Peрe, Mr. Pepe’s line source, Anthony DiGiacomo and Michael Niland. [emphasis added]
These conclusions that five persons participated in the business, and similar conclusions with respect to Mr. DiGiacоmo, 6 were implicitly based on the District Court’s Finding of Fact No. 3:
Mr. Pepe had an arrangement with an individual [i. e. his unnamed “line source”] other than one of the named defendants pursuant to which he received line information for use in his business.
It is this latter determination which the DiGiacomo panel of this court found to be “completely devoid of minimum evidentiary support,” resulting in clear error and a reversal of Mr. DiGiaeomo’s conviction. 7
Mr. Carucci’s failure to challenge the District Court’s specific findings of faсt does not preclude this court from reviewing them. Appellate courts
*1137
may notice errors apparent on the face of the record, but not urged by either party, in order to prevent a manifest miscarriage of justice. United States v. Musquiz,
There being established only four participants, Messrs. Pepe, Nilаnd, DiGiacomo and Carucci, in the gambling business, we conclude that the Government failed to prove that the object of the conspiracy was a federal offense.
Appellant Carucci’s conviction on the conspiracy count, Count II of the indictment, will be reversed. Under this disposition of the case it becomes unnecessary for us to decide Mr. Carucci’s contention that an uncompensated participant may not be convicted of conspiring to violate the fedеral gambling statute.
