Appellants Ho Chong Tsao, Hung Hoi Che, and Cheung Chan have appealed from orders of deportation entered against them pursuant to § 241(a)(2) of the Immigration and Nationality Act, 8 U.S.C. § 1251(a)(2) for having remained in the United States longer than authorized. All three appellants are deserting seamen who were arrested in Dallas by officers of the Immigration and Naturalization Service approximately one week after their ships had departed.
The following issues are raised by the appellants: (1) whether the evidence used to establish their deportability was tainted within the meaning of
Wong Sun v. United States,
I.
The evidence objected to by appellants consists of their passports and records of failure to depart. It is an undisputed fact that the Immigration and Naturalization Service had these items in its files prior to the time that appellants were arrested. An analogous situation was before this court in
United States v. Martinez,
II.
We also feel that the immigration judge’s decision not to allow appellants to testify about the circumstances surrounding their arrest was proper. “To prove overstay, the respondent need only show a non-immigrant’s admission for a temporary period, that the period has elapsed, and that the nonimmigrant has not departed.”
Milande v. Immigration and Naturalization Service,
III.
Appellants’ next contention is that the burden of proof was improperly allocated because the immigration judge did not allow them to challenge the admissibility of the documents that established their deportability. We hold that this argument is also without merit since the immigration judge agreed to permit testimony by appellants on the question of whether they were in possession of the documents used to es *669 tablish their deportability at the time of their arrest.
IV.
The final group of issues raised by appellants relates to the composition of the Board of Immigration Appeals.
First, appellants contend that the decision of the Board was invalid because only three of five members heard the appeals. 8 C.F.R. § 3.1(a) was amended on August 26,1975 to provide that three members of the Board of Immigration Appeals constitutes a quorum. Unfortunately, this regulation was not in effect at the time that the Board rendered its decision in these cases; however, since the enabling statute is silent on this issue, we feel that the amendment is a codification of previously existing common law. “. .in the absence of a contrary statutory provision, a majority of a quorum constituted of a simple majority of a collective body is empowered to act for the body. Where the enabling statute is silent on the question, the body is justified in adhering to that common-law rule.”
F. T. C. v. Flotill Products, Inc.,
We likewise reject appellants’ contention that the decision of the Board of Immigration Appeals is defective under § 5 of the Administrative Procedure Act, 5 U.S.C. § 554(d). 1
The Third Circuit recently held in
Giambanco v. Immigration & Naturalization Service,
Under Marcello v. Bonds,349 U.S. 302 ,75 S.Ct. 757 ,99 L.Ed. 1107 (1955), the hearing procedures of the immigration judge are not subject to the A.P.A. The question here is whether the Board, which sits in review of these determinations and is established at the discretion of the Attorney General, 8 U.S.C. § 1252(b), is also exempt from A.P.A. requirements. We think it is, for it would be anomalous to find that the initial immigration hearing was exempt, only to say that the review of such hearing was not exempt. To so hold would interject needless complexity into what is designed to be a discretionary process and require different standards for separation of adjudicative and prosecutorial functions for immigration judges and the Board members.
AFFIRMED.
Notes
