These five cases, consolidated for trial, present the claims of 65 investigators of the Alcohol and Tobacco Tax Division, Internal Revenue Service, for overtime compensation under the Federal Employees Pay Act of 1945, 59 Stat. 295 (1945), as amended. The actual performance by a number of plaintiffs of work outside or, in addition to, the normal workweek of five eight-hour days, is not in dispute. The principal issue is whether the extra hours actually worked were officially ordered or approved within the meaning of the statute and pertinent regulations.
Section 201 of the Act provides in part as follows:
“Officers and employees to whom this title applies shall, in addition to their basic compensation, be compensated for all hours of employment, officially ordered or approved, in excess of forty hours in any administrative workweek, at overtime rates as follows: * * *” (59 Stát. 296) Section 605 of the Act provides:
“The Civil Service Commission is hereby authorized to issue such regulations, subject to the approval of the President, as may be necessary for the administration of the foregoing provisions of this Act insofar as this Act affects officers and employees in or under the executive branch of the Government.” (59 Stat. 304)
A later 1954 amendment authorized department heads with Civil Service Commission approval to provide that:
“(2) any officer or employee in a position in which the hours of duty cannot be controlled administratively, and which requires substantial amounts of irregular, unscheduled, overtime duty and duty at night and on holidays with the officer or employee generally being responsible for recognizing, without supervision, circumstances which require him to remain on duty, shall receive premium compensation for such duty on an annual basis in lieu of premium compensation provided by any other provisions of this Act, except for regularly scheduled overtime duty.” (Sec. 401(2), 68 Stat. 1111 (1954)
Under the authority of this statute and pertinent Civil Service Regulations, the Treasury Department delegated authority to the Internal Revenue Service for application of the 15 percent premium pay provisions, with appropriate rules for entitlement thereto.
These Regulations provided that:
“No overtime * * * shall be ordered or approved except in writing by an officer or employee to whom * * * authority has been specifically delegated by the head of the department. * * * ” [Emphasis supplied.] (Exec. Order No. 9578, 10 Fed.Reg. 8194 (1945), U.S. Code Congressional Service 1945, p. 1267)
In all of its nine Federal Regions, the Alcohol and Tobacco Tax Division of the Internal Revenue Service authorized and paid the 15 percent annual premium pay allowed by statute in lieu of regular overtime to all of its investigators who were entitled thereto under the rules, beginning June 28, 1955. After three months, however, these payments were discontinued in the San Francisco and Omaha Regions, upon the insistence of the national office that these two regions were not faced with a critical liquor enforcement problem. The regional officers in these two regions thereafter refused to authorize premium pay or regular overtime to their investigators, including plaintiffs.
*968On September 23, 1955, the San Francisco Regional Chief of Enforcement, pursuant to instruction from the national •office, which he later protested, notified the investigators of the termination of their 15 percent annual premium pay in lieu of overtime, but nevertheless added in the notice this statement:
“ * * * and it is expected that you will perform without extra compensation any overtime that may be necessary to make good cases and achieve effective results in our enforcement work.”
This directive remained in effect. On June 13, 1958, the San Francisco Region instructed its supervisors that: “Most investigators by the very nature of their responsibilities must work irregular hours and perform many hours of overtime duty.”
The Civil Service Commission in December, 1955, described the position of these investigators as follows:
■“ * * -x- An agent may be frequently called upon to serve in an undercover capacity requiring that he live and associate with criminals for lengthy periods. * * * Performance of these duties may require work at irregular hours, involve personal risks, exposure to all kinds of weather, arduous physical exertion under rigorous and unusual environmental conditions, and considerable travel. * * * ” [Emphasis supplied.]
The record here is replete with evidence that these plaintiffs were called upon to “work at irregular hours” and “for lengthy periods” under the same arduous conditions described above by the Civil Service Commission in prescribing the required conditions for granting premium pay. When premium pay of 15 percent was discontinued, the workweek requirements for plaintiffs remained the same throughout the period in litigation. They were, by express directive, subject to duty twenty-four hours a day. They were obliged to exercise independent judgment with respect to overtime in order to complete an investigation, or when the occasion demanded. Their overtime duty could not be administratively controlled, and it was impractical, if not impossible to secure specific advance authorization for overtime in view of the nature of the work involved.
At a meeting of officials of the Omaha Region, a statement was made that investigators could not be compelled to work overtime without additional compensation, but they could be made to wish they had done so. In a statement circulated to its investigators, the Omaha Division, after outlining the onerous and difficult nature of the duties involved, added this admonition:
“Investigators are subject to duty twenty-four hours per day, and are often on duty as much as eighteen hours.” [Emphasis supplied.]
These directives in both regions were in clear violation of the statutes and regulations, and particularly the following Treasury Department Regulation, IR-Circular No. 57-4:
“Section 7. Ordering or Approving Overtime Duty
“.05 A supervisor’s non-compliance with the requirement that authorization or approval of overtime be in writing while at the same time either ordering overtime duty orally or requesting the performance of work outside f>f regular tours of duty on a voluntary basis directly or indirectly by implying that employees not ‘volunteering’ will be in disfavor, cannot and shall not be condoned. Practices of this kind, which may be justified in the mind of the supervisor as being in the interest of the Service, are in direct conflict with Service policy and the intent of law. These practices give rise to complaints of employees being ‘coerced’ to work overtime without receiving pay or compensatory time off.” [Emphasis supplied.]
In 1956, this court held that patrol inspectors of the Customs Border Patrol, who performed overtime work without *969compensation under the same statute and circumstances and regulations similar to the instant case, were entitled to recover overtime. Arnvid Anderson et al. v. United States, (1956) 142 F.Supp. 902, 136 Ct.Cl. 365.
The court found that the “Commissioner of Customs and his subordinates rationalized the concept of voluntary overtime into the course of conduct by which the patrol inspectors were induced to perform the overtime work.” The court further found that “the withholding of written orders or approval reflected observance of the letter of the regulation but denial of the substance of the statute,” and concluded that plaintiffs therein “were induced to perform the overtime” by the district and national officers of the Customs Bureau. The same conclusion was reached in Adams et al. v. United States, Ct.Cl.No.66-59, decided July 12, 1963.
We consider that this conclusion is equally applicable to the facts now before us. The directives to the investigators from the Omaha and San Francisco Regional Offices were issued under orders from the National Office, requiring adequate enforcement of the liquor laws, and at the same time requiring discontinuance of overtime and premium pay for essential work. There is no evidence of bad faith or subterfuge, indeed, the Regional Officers were completely candid in advising the investigators that, although they would be expected and required to work overtime, they would not be paid for it. This candor, however, does not relieve the Government of its responsibility under the statute to pay overtime or premium pay for authorized extra work. The invocation of departmental regulations requiring specific written authority for overtime cannot avoid the plain requirements of the statute for overtime pay when the performance of this overtime is induced by the Government, as it was in Anderson, supra, and in this case.
This inducement by defendant went beyond the “tacit expectation” which this court held was not equivalent to the statutory requirement of “official order or approval” in Albright et al. v. United States, Ct.Cl.No.263-61, decided April 5, 1963. In the present ease, the “expectation” was not tacit; it was made so explicit in terms as to amount to inducement and compulsion.
Defendant contends that if “inducement” is to be equated with an “order” or “approval” it must proceed from an authorized official, in this case, the Regional and Assistant Regional Commissioners for Alcohol and Tobacco Tax Division. The evidence in this case fully supports the conclusion by the Trial Commissioner that plaintiffs’ overtime work was performed with the full knowledge, encouragement and inducement of these officials, as well as the officials in the National Office. Indeed, the Treasury Department itself provided, following the 1954 amendment to the 1945 Pay Act that:
“[Section 4, paragraph .05] The extent of the nontaxpaid liquor traffic in any given area must necessarily be the basic factor in guiding supervisory officials in determining whether any officer who meets the individual qualifications can qualify for premium pay. Obviously, in many areas the volume or scope of the nontaxpaid liquor traffic is such as to not necessitate frequent, unscheduled overtime, consequently officers cannot qualify for premium pay. This does not, however, relieve the individual investigator of the obligation to answer the call of duty when the occasion demands.” [Emphasis supplied.]
The Regional and National Offices of the Alcohol and Tobacco Tax Division regularly received periodic reports of the overtime worked by all investigators in the regions during the period involved in this litigation, and either approved or acquiesced therein. These reports were prepared on the basis of regular daily reports by the investigators, including all hours of overtime and an explanation thereof to their supervisors who were primarily responsible for appraisal of *970essential overtime. These reports were the required basis for payment of either regular or 15 percent premium overtime pay. There is no evidence of any official disapproval of these overtime reports during the period involved in this case.
Plaintiffs’ claim for overtime pay arose almost entirely after the 1954 amendment of the Federal Employees Pay Act providing for authorization of 15 percent annual premium pay in lieu of regular overtime pay. Neither the Internal Revenue Service nor the Alcohol and Tobacco Tax Division ever authorized premium pay in lieu of regular overtime during the period involved in this litigation.
In providing for annual premium pay in lieu of regular overtime pay by the 1954 amendment to the Pay Act of 1945 (sec. 401(2) supra), Congress made this provision mandatory when applicable. Employees whose hours of duty could not be controlled administratively, and whose position required substantial amounts of irregular, unscheduled overtime, night and holiday-duty with the employee generally being responsible for determining the necessity for remaining on duty overtime, “shall receive premium compensation for such duty on an annual basis in lieu of premium compensation * * * except for regularly scheduled overtime duty.”
Plaintiffs never performed “regularly scheduled overtime duty.” Their hours of duty come squarely within the purview of the annual premium pay subsection, in fact, all of the investigators in the other seven Regions were paid under the authority of this same subsection. The language of the subsection is mandatory, not discretionary or permissive. Such employees “shall receive premium compensation.”
Plaintiffs never performed “regularly scheduled overtime duty,” as provided for in this subsection, and they are entitled to the same annual premium pay of 15 percent allowed in the other seven Regions.
Section 1939.5(7) (d) of the Internal Revenue Manual states that “rarely can time spent in travel status outside the regularly scheduled tours of duty be considered as overtime work.”
The record does not warrant the inclusion of hours of travel accomplished by any of the plaintiffs herein for purposes of allowing overtime pay provided by the Federal Employees Pay Act of 1945, as amended, supra. It was an incident of the performance of duty, necessary and authorized, but the record here does not warrant inclusion of the hours of ordinary normal travel as a basis of granting extra pay beyond the per diem allowed while away from official station.
Defendant has pleaded for a denial of any recovery for the years preceding 1956 in the claims presented by plaintiffs Grimes, Gibson, and Lashbrook under “the equitable rule of laches.” All periods involved in computations made concerning any of the plaintiffs are within the six-year period immediately preceding the filing dates of the claims. Obviously, plaintiffs herein are not responsible for any destruction by defendant of any records pertaining to these claims.
Plaintiffs are entitled to recover annual premium pay of 15 percent for the irregular, unscheduled overtime work performed by them during the periods covered by their respective claims, less any additional compensation already paid, and without allowance of any hours spent in travel status and claimed by plaintiffs as overtime, and with an allowance for any overtime which accrued prior to the effetive date of the 1954 amendment at regular overtime rates. Judgment is entered to this effect, with the amount due each plaintiff to be determined in further proceedings under Rule 38(c).
