*125MEMORANDUM AND ORDER SUR PLEADINGS
This is a proceeding for review of Respondent’s Certification of the Virgin Islands Labor Union, AFL-CIO, as the representative for collective bargaining of “all ticket sellers, ticket collectors, poster distributors, cleaners; excluding all office clerical employees, air-conditioning maintenance men, projectionists, watchmen and supervisors”, which were found to constitute a unit appropriate for collective bargaining. This proceeding is brought pursuant to 5 V.I.C. §§ 1421-1423. See Caribe Construction Co. v. Penn, 342 F.2d 964, 5 V.I. 180 (1965).
After a careful review of the record and, in particular, consideration of the last sentence of 24 V.I.C. § 67(a),1 the court has concluded that the Petition For A Writ of Review must be denied. The findings of respondent are supported by substantial evidence. Although there appear to have been reasons indicating that the Commissioner of Labor might have made a further investigation of the statement by 15 employees that “we do not want to be represented by any Labor Union for collective bargaining or for any other purpose. Any signature that may appear to the contrary in any petition prior to this date, April 25, 1967, is void”,2 he had the discretion not to make such further investigation and the applicable legislative provisions, in the light of this record, do not permit us to modify his certification and unit determination.
