Frоm October 1969 to January 1970, Neuhoff Bros. Packers, Inc. (Neuhoff), *819 defendant-appellee, a Dallas, Texas meat packing concern, missed meat from its meat packing plant and suspected several of its employees of theft. Following investigation it discharged two employees, Franklin and Green, who thereupon instituted arbitration proceedings pursuant to the collective bargaining agreement in effect betwеen Neuhoff and the employees’ representative union, Amalgamated Meat Cutters and Butcher Workmen of North America, District Local 540, plaintiff-appellant. After hearing the evidence, the arbitrator ruled the discharges to be without “proper cause” and ordered reinstаtement of the grievants with back pay. Neuhoff has refused to abide by the arbitrator’s order, thus prompting the union to seek the assistance of thе district court in the enforcement of the arbitrator’s award as provided by section 301 of the Labor Management Relations Act, 29 U.S.C. § 185. Denied reliеf below, the union appeals. We reverse.
Evidence adduced at the arbitration hearing indicated that grievant Franklin had taken a lie dеtector test but had refused to take a second one when ordered to do so by Neuhoff. Green, the other grievant, took both lie detector tests and allegedly failed to clear himself of dishonesty. The arbitrator admitted the tests’ results into evidence, but only for the purpose of shоwing that Neuhoff had received certain statements from the grievants and not as evidence of whether the person taking the test was telling the truth. The arbitrator, (1) concluded (a) that in cases involving “moral turpitude or criminal intent,” Neuhoff had the burden of proving its allegations of such actions “beyond a reasonable doubt” and had failed to do so here, and (b) the results of polygraph tests need not be considered as evidencе of guilt even though the collective bargaining Zheement provided that the company rid require polygraph tests of any employee suspected of theft of company property; and (2) declined to rule that grievant Franklin’s refusal to take a second lie detector tеst was per se grounds for discharge under the parties’ agreement. The district court, in refusing to enforce, (1) found the arbitrator had (’a) violated thе collective bargaining agreement provision that he not “. . . add to, modify, detract from or alter [it] in any way . . .’’by imposing upon Neuhoff the burden of proving grievants’ guilt “beyond a reasonable doubt” and (b) exceeded his authority in that his refusal to consider the tests’ results was nonrecognition of the collective bargaining agreement’s provision that Neuhoff reserved the right to require polygraph tests of any employee suspected of theft; and (2) found grievant Franklin’s refusal to take the second polygraph test to be of itself proper cause for his discharge.
The scope of judicial review of an arbitrator’s award is extremely narrow: in order to promote the federal policy favoring settling labor disрutes by arbitration the factual and the legal accuracy of arbitrators’ findings will not be reviewed.

In these circumstances it was not impermissible for the arbitrator, as a basic part of his decisional process, to establish what he considered an appro

priate standard, viz., proof beyond a reasonable doubt. We note, further, that the arbitrator’s selectiоn was consistent with general arbitration practice under similar agreements where the discharge involves criminal intent or moral turpitude.

The company next claims that the terms of the agreement were violated by the arbitrator’s exclusiоn of the polygraph tests taken by the employees. The agreement provides that the company “reserves the right to require .... polygraph-tests of any employee in case the company suspects . . . theft of company property.” It makes no mention, however, of the use
vel non
of such tests in an arbitration proceeding. Since, as the company concedes, polygraph tests may be valuable in a number of ways, including preliminary investigation, to deny their use in one specific context does not render the contract provision meaningless. Viеwed as a question of admissibility of evidence, the arbitrator has great flexibility and the courts should not review the legal adequacy of his evidentiаry rulings.

The final issue concerns the refusal of one of the emplоyees, Franklin, to take a second polygraph test. Although the arbitrator made no finding on this point, the district court ruled that, as a matter of law, Franklin’s refusal constituted proper cause for discharge. We must regard this action by the district court as singularly unwarranted. The agreement does not specify individual grounds for discharge. Rather, by using only the general words “proper cause,” it leaves the question of what is a good reason for discharge —the ultimate disciplinary measure — for subsequent interpretation. As the court said in International Union of Electrical Radio and Maсhine Workers v. Otis Elevator, 2 Cir., 1963,
The award must be reinstated and enforced. Reversed.
