What follows is an opinion from the Supreme Court of the United States. Your task is to identify the court in which the case originated. Focus on the court in which the case originated, not the administrative agency. For this reason, if appropiate note the origin court to be a state or federal appellate court rather than a court of first instance (trial court). If the case originated in the United States Supreme Court (arose under its original jurisdiction or no other court was involved), note the origin as "United States Supreme Court". If the case originated in a state court, note the origin as "State Court". Do not code the name of the state. The courts in the District of Columbia present a special case in part because of their complex history. Treat local trial (including today's superior court) and appellate courts (including today's DC Court of Appeals) as state courts. Consider cases that arise on a petition of habeas corpus and those removed to the federal courts from a state court as originating in the federal, rather than a state, court system. A petition for a writ of habeas corpus begins in the federal district court, not the state trial court. Identify courts based on the naming conventions of the day. Do not differentiate among districts in a state. For example, use "New York U.S. Circuit for (all) District(s) of New York" for all the districts in New York.

Opinion:
WALLING, WAGE AND HOUR ADMINISTRATOR, v. GENERAL INDUSTRIES CO.
No. 564.
Argued February 10, 11, 1947.
Decided March 31, 1947.
George M. Szabad argued the cause for petitioner. With him on the brief were Acting Solicitor General Washington, Philip Elman, William S. Tyson, Bessie Margolin and Morton Liftin.
Glen 0. Smith argued the cause for respondent. With him on the brief were M. Reese Dill and Carl F. Shuler.
Mr. Chief Justice Vinson
delivered the opinion of the Court.
In a complaint filed in the District Court, petitioner charged that respondent was violating the Fair Labor Standards Act by failing to pay some of its employees time and one-half for statutory overtime, as required by § 7 (a) of the Act, and asked an injunction against continued violation. Respondent denied the charge, and separately alleged that any of its employees not compensated in accordance with the requirements of § 7 (a) were exempt from the Act by § 13 (a).
The Court, without a jury, heard witnesses for both parties with respect to the compensation and status of three engineers in respondent’s power plant. It made special findings of fact, concluded that these men were exempt employees, and entered judgment for respondent. The Circuit Court of Appeals thought the evidence did not sustain the District Court’s findings relative to the engineers’ exempt status. But it thought that the District Court had also found the engineers’ compensation to be in accordance with the Act. It decided that the evidence was adequate to this end, and affirmed the District Court’s judgment. We granted certiorari to determine whether the ruling of the Circuit Court of Appeals was not inconsistent with this Court’s decision on computation of overtime in Overnight Motor Co. v. Missel, 316 U. S. 572. On argument here, however, respondent continued to urge that the District Court was warranted in its findings as to the engineers’ exempt status. Having heard the argument and examined the record, we agree that it was. Therefore, we need not consider further the question of computation of overtime, and proceed only to state the considerations relevant to the particular ground of our decision.
There is no dispute as to the applicable law. Section 13 (a) exempts from the overtime provisions of the Act any person employed in an “executive capacity” as defined in regulations issued by the Administrator. The Regulations prescribe six conjunctive conditions to an executive capacity, which are set forth in the margin. Respondent had the burden of proving the existence of these conditions, if it would rely on its defense that the engineers were exempt employees.
There was evidence to the following effect. Respondent operates at Elyria, Ohio, a plant engaged in the production of small motors and plastic products. Part of this plant consists of a powerhouse containing a boiler room and engine room. In the former are four boilers. These supply the steam required to drive three large electrical generators which are the source of power for the entire plant, and to create the high steam-pressures and air-pressures employed in molding plastics. In the engine room, besides the generators, are compressors, engines, and other equipment. All this machinery, in both rooms, constitutes an interrelated and interdependent system. It must be carefully and skillfully tended at all times in order to maintain the power and pressure required for continuous 24-hour operation of the plant, to avoid damage to the tremendous investment in the machinery itself, and to guard against the fearful consequences of an explosion.
During the period covered by the evidence, the powerhouse was manned by the following personnel. At the top was the chief engineer, who apparently adhered to no precise duty-hours, but was customarily present most of the morning and afternoon and subject to call, in the event of an emergency, twenty-four hours a day. Directly under and responsible to him were the three “operating engineers” whose status is in issue. They worked consecutive eight or eight and one-half hour shifts, one of them being present in the powerhouse at all times. Finally, there were an unspecified number of firemen and coal-passers, who, collectively, were also on twenty-four hour duty.
The engineers in question were paid regular monthly salaries of more than $200 per month, for which they regularly worked six-shift weeks. They received sick leave, vacations with pay, bonuses, insurance, and pension rights usually reserved for supervisory employees.
The engineers were in charge of the powerhouse and performed the duties generally incident to direct supervision of a highly mechanized operation. Respondent’s vice president and factory manager testified that they acted as foremen of the firemen and coal-passers. This testimony was corroborated by other facts. In July, 1944, two months before the complaint in this case was filed, the engineers signed agreements with respondent stating their desire “to be regarded as Foremen, as in the past, with Foremen privileges and continue on a salary basis.” Three weeks later the International Brotherhood of Firemen, Oilers and Helpers abandoned a long-contested claim of right to represent the engineers, thereby formally recognizing their supervisory status. Indeed, the nature of the operations in the powerhouse was such that the immediate and continuous supervision of trained persons was indispensable, and there were concededly no other employees to give such supervision. The engineers were required to maintain constant observation of all machinery in the powerhouse, and to make regular inspections and necessary repairs. In addition they were required to spend a small part of their time in oiling and cleaning the engines.
The District Court, having made findings substantially as stated above, proceeded to make additional findings of the existence of each of the facts on which an executive status, as defined by the Regulations, is made to depend.
We believe that the evidentiary facts afford an adequate basis for the inferences drawn by the Court in making such additional findings. At the least, we think that in drawing such inferences the Court was not clearly wrong, and conclude that the findings should therefore have been left undisturbed. The Circuit Court of Appeals’ rejection of those findings cannot rest on the conflicting testimony of petitioner’s witnesses. The District Court heard the witnesses, and was the proper judge of their credibility.
Affirmed.

“(b) who customarily and regularly directs the work of other employees therein, and
“(c) who has the authority to hire or fire other employees or whose suggestions and recommendations as to the hiring or firing and as to the advancement and promotion or any other change of status of other employees will be given particular weight, and
“(d) who customarily and regularly exercises discretionary powers, and
“(e) who is compensated for his services on a salary basis at not less than $30 per week (exclusive of board, lodging, or other facilities), and
“(f) whose hours of work of the same nature as that performed by nonexempt employees do not exceed 20 percent of the number of hours worked in the workweek by the nonexempt employees under his direction; provided that this subsection (f) shall not apply in the case of an employee who is in sole charge of an independent establishment or a physically separated branch establishment.”
