The Ministry of Labour appealed the acquittal of an employer charged under the Occupational Health and Safety Act after a worker suffered a serious hand injury on a cold-rolling steel mill.
The employer argued it complied with the guarding requirement in section 25 of the Industrial Establishments Regulations by using a push bar and an operating control, and that the worker's deliberate failure to follow procedures caused the accident.
The Court of Appeal allowed the appeal, holding that the push bar and operating control did not constitute a guard or 'other device' under the Regulation.
The Court further held that employee misconduct is not a defence to the strict liability offence of failing to guard a machine, and the employer failed to establish a due diligence defence.
A conviction was entered.
