The applicant employer sought judicial review of a labour arbitrator's decision reinstating a railway conductor who was terminated following a positive urine test for marijuana.
The employer argued the arbitrator unreasonably excluded an expert report on marijuana impairment tendered eight days before the hearing.
The Divisional Court dismissed the application, finding the arbitrator reasonably exercised his discretion to exclude the late report to protect the integrity and fairness of the expedited arbitration process.
The Court also upheld the arbitrator's conclusion that a positive urine test, without corroborating evidence of impairment, did not establish a violation of the employer's drug policy.
