Michael Jacobs, an officer in the United States Coast Guard, contends that the four years he spent as a cadet at the Coast Guard Academy should be counted in satisfying the 20 years of active service required for voluntary retirement under 14 U.S.C. § 291. After exhausting his administrative remedies, 1 Jacobs sought a declaratory *89 judgment that he had completed 22 years of active service — four years as a Coast Guard Academy cadet and 18 years as a commissioned officer — and was therefore entitled to retire. On cross-motions for summary judgment, the district court held for the Government. We affirm.
The controlling question in this case is whether cadet time may be credited in computing length of service for retirement eligibility under 14 U.S.C. § 291. 2 The critical statute is 10 U.S.C. § 971(b). 3 Section 971(b) prohibits any officer of the Navy, Marine Corps, Army, or Air Force from counting “for any purpose” time spent as a cadet or midshipman (pre-commission status) in any of the service schools, including the Coast Guard Academy. Relying on the maxim expressio unius est exclusio alterius, Jacobs argues that because § 971(b) applies, on its face, to every branch of the armed services except the Coast Guard, Congress necessarily intended to allow Coast Guard officers to credit time spent as cadets at the Coast Guard Academy toward retirement eligibility.
The Government returns Jacobs’ fire with its own canons of statutory construction. The Government’s principal contention is that military benefit provisions should be construed to apply equally to all five branches of the military service unless Congress expressly indicates otherwise. The Government points out that Jacobs’ position would be unfair both to officers in other services who attended a service school and to the many Coast Guard officers who did not attend a service school.
Because we find neither party’s statutory construction arguments entirely persuasive, we turn to § 971(b)’s legislative history for guidance.
See Cass v. United States,
Jacobs’ contention that Congress manifested its intention to change the longstanding practice of prohibiting Coast Guard officers from counting academy time by repealing 14 U.S.C. § 461(a), the “linkage” provision, is refuted by the legislative history accompanying the 1968 Act 5 which, inter alia, added subsection (b) to § 971. As noted in footnote 3, supra, and accompanying text, subsection (b) is the key provision regarding use of service school time in computing length of service. In its analysis of the first section of the Act, the Senate Armed Services Committee reported that:
The new section is also made applicable to the Coast Guard upon the'recommendation of the General Counsel of the Treasury that “general military law applicable to the Armed Forces should also be applicable to the Coast Guard.” Consequently, other sections of the bill generally applicable to the Army, Navy, Air Force and Marine Corps [such as section six containing the addition of subsection (b) to 10 U.S.C. § 971], have also been made applicable without further specific comment ... to the Coast Guard.
S.Rep.No. 931, at 3, reprinted in [1967] U.S. Code Cong. & Ad.News 2635 at 2637 (bracketed material added).
We believe that this legislative history removes any vestige of doubt about the correctness of the government position. In light of the legislative history accompanying § 971(b) and its predecessor provisions, and the fact that the government’s position promotes equality of treatment among the officers of all five branches of military service and is consistent with 70 years of uniform administrative practice, we hold that § 971(b) applies to Coast Guard officers to the same extent as it does to officers of the other service branches.
Our decision obviates the need to determine whether academy time may be counted in computing retirement pay under 14 *91 U.S.C. § 423. Jacobs concedes that the retirement pay issue is controlled by the same considerations as the length-of-service issue under § 971(b).
The district court’s decision is AFFIRMED.
Notes
. In
Linfors v. United States,
. 14 U.S.C. § 291 provides that a regular commissioned Coast Guard officer may retire upon completion of 20 years of “active service.” Although Title 14 (pertaining to the Coast Guard) does not provide a definition of active service, the term is defined generally in Title 10 (pertaining to all the Armed Forces) to mean “service on active duty.” 10 U.S.C. § 101(24). “Active duty” is, in turn, defined to mean “full-time duty in the active military service of the United States.” 10 U.S.C. § 101(22). Subsection (22) further provides that “active duty” includes “attendance, while in the active military service, at a school designated as a service school.... ” We agree with the district court that, because of the phrase “while in the active military service,” subsection (22) refers to education that takes place after an officer has been commissioned, and not, as Jacobs contends, before. Moreover, as evidenced by 10 U.S.C. § 971(b), the question of whether cadet time constitutes active service is not controlling here.
. 10 U.S.C. § 971(b) provides that:
(b) In computing length of service for any purpose—
(1) no officer of the Navy or Marine Corps may be credited with service as a midshipman at the United States Naval Academy or as a cadet at the United States Military Academy, United States Air Force Academy, or United States Coast Guard Academy, if he was appointed as a midshipman or cadet after March 4, 1913; and
(2) no commissioned officer of the Army or Air Force may be credited with service as a midshipman at the United States Naval Academy or as a cadet at the United States Military Academy, United States Air Force Academy, or United States Coast Guard Academy, if he was appointed as a midshipman or cadet after August 24, 1912.
. In the Act of June 10, 1922, 42 Stat. 625, 627, Congress abolished academy credit to officers of all the services, including specifically the Coast Guard. That Act provided that officers appointed after July 1, 1922 could only count active commissioned service for purposes of pay. As noted in
Williams v. United States,
. Act of Jan. 2, 1968, Pub.L.No.90-235, § 6(a)(1), 81 Stat. 753, 761. The “principal objective” of the Act was to make:
[Tjitle 10 clear and simple by identifying (1) separate statutes applicable to different Armed Forces that could be consolidated in the General Military Law subtitle of title 10; (2) archaic provisions of law that have no current or foreseeable future application; and (3) variations in personnel laws for which there is no justification. The bill covers such subjects as ... miscellaneous rights and benefits, ... and periods of active duty.
