As a defence to the claim, McIntosh had argued that his positioned had changed and he had embarked on a residential property development since receiving the payment.
There was no suggestion McIntosh had any reason to suspect when he got the money back in 2011 that Ross was running a ponzi scheme.
But the judge said by the time McIntosh had entered into the building contract in July 2013 he was well aware the profit paid to him was fictitious.
Ross' business - Ross Asset Management - collapsed in November 2012, around the time it was raided by the Financial Markets Authority.
It was later revealed that Ross was running a ponzi scheme and he was jailed for 10 years and 10 months.
"I do not consider that, following the first public revelation of RAM's position, a reasonable person in the respondent's position could have held a reasonable belief that the payments were valid and would not be set aside," Justice Mackenzie said in his decision today.
RAM's liquidators said they intend to push forward with the remaining two test cases due to go to court later this year.
They are "also reviewing the position of a number of other investors who have received payments from RAM in the period leading up to the company's liquidation".
One of the liquidators, John Fisk, said around 193 investors may now face claims for recovery of $30 million of "fictitious profits".
These investors are all believed to have got out more than they put into the business.
McIntosh did not return messages yesterday.
Any money that liquidators claw back improves the return for about 1200 investors, who lost $100-$115 million in Ross' fraudulent scheme.
