But ERA member Paul Stapp in July last year said there were doubts "around the proper authority surrounding the matter of the bonus payment" and dismissed West's claim to it.
Stapp, however, said PGC had "completely failed to meet its obligations to give Mr West a reasonable opportunity to respond to the employer's concerns".
"It failed to put the allegations upon which Mr West was dismissed, and he was disadvantaged without any opportunity to properly respond to the allegations before the dismissal," Stapp said.
Stapp awarded West $120,833 in lost wages, $2743 in interest, and $10,000 in compensation for hurt and humiliation. PGC also agreed to pay West $22,065 in holiday pay and interest.
Both PGC and West have challenged aspects of the ERA's decision to the Employment Court.
As part of that dispute, West sought disclosure of documents from his former employer, including board minutes approving the company's 2011 financial statements and executive bonuses.
He also wanted access to emails relating to that board meeting.
PGC said some of these documents were legally privileged and, in any event, no documents existed in the category which West was asking for.
But Judge Bruce Corkill said this objection was "ill-founded" and that the PGC should disclose the documents requested to West.
