However in his written conclusion, Judge Mark Perkins said Mr Belsham was not correct in his assertion that the reason that he would not work was due to health and safety concerns, but instead due to a grievance to do with rosters.
"It is significant also that if the issue with the container was as serious as Mr Belsham maintained, other employees would have taken the same stand as he did, but none did," Judge Perkins said.
"Certainly, there was no evidence from any other employee that the vessel was unsafe to discharge."
Although Mr Belsham refused to work for a relatively short period, it proved a substantial dereliction of duty, the court's judgement stated.
"The vessel being discharged presented a difficult situation at the port. The company had a contingency plan in place. That plan had been presented to Mr Belsham."
Mr Belsham's clear deceit and his curious actions in the disciplinary process meant that the employer was entitled to take the view that it could no longer have trust and confidence in him as an employee, the judgement stated.
"In all of the circumstances, the dismissal was an action which a fair and reasonable employer could take. Accordingly, the challenge is dismissed."
Costs were reserved.
