The Federal Court of Canada ruled that the Government of Canada is liable in damages for the negligent port state control (PSC) inspection and detention of a foreign vessel. In the instant case, a Canadian PSC boarding officer, trained as a machinery inspector, but not as a naval architect, determined after a cursory inspection that certain frames on the vessel were excessively wasted and must be replaced before the vessel could depart the port. His arbitrary determination was inconsistent with the standards of the flag administration and the classification society and its basis was not substantiated. The ship owner’s appeal was denied by higher authority within the Canadian Government following a delayed and perfunctory review.
