Champion boxer Anthony "the man" Mundine has criticised Redfern police for "blatant racism" after a case against his cousin was thrown out of court.

Mundine was at Central Local Court this afternoon to support his cousin, Matthew Coe, who was pulled over on January 28 in Redfern and found to have $3900 in his car.

The court heard that officers had conducted the search after pulling Mr Coe's Nissan Skyline over for a traffic offence and smelling cannabis smoke in the car.

There were different versions from various police witnesses about what happened next, but it was alleged that Mr Coe told officers the car belonged to his cousin and he had "never seen the money before in my life ... but I'll claim it".
