203.—Whenever required so to do by any court, it is the duty of a local authority, to produce to that court a true copy of any bye-law and to verify the copy to that court by having endorsed on the copy a certificate signed by an employee (whose official position it is not necessary to prove) of the local authority, by which the bye-law was made and that court shall receive the copy in evidence and, accordingly, the copy as so certified is evidence of the bye-law unless the contrary is shown.
