Justice Choo rejected the testimony of ERA's top brass - president Jack Chua and senior vice-president Marcus Chu - that the two men had done nothing wrong.
The judge said it was clear why they thought so - Mr Chu admitted in court that he and others in the company, as well as agents in other companies, had done the same thing.
Justice Choo also rejected arguments by ERA that it was not liable for the actions of its agents, who are 'independent contractors'.
The option form had ERA's logo printed on it; the commission agreement was between Madam Wong and ERA; and the newspaper advertisements sought to persuade the public that they would have the backing of the company and its network by engaging an ERA agent.
It was also ERA - not Mr Ang - which took the couple to the Small Claims Tribunal when they refused to pay the commission on the sale.
