Woolworths has been fined $9 million over its role in a laundry detergent cartel case brought by the competition watchdog.
The supermarket giant has admitted to being "knowingly concerned in an anti-competitive understanding" between detergent producers Colgate-Palmolive, PZ Cussons and Unilever Australia, Australian Competition and Consumer Commission chairman Rod Sims said in a statement on Friday.
The Federal Court penalty, handed down after the ACCC commenced proceedings in 2013, is the largest the regulator has obtained against a party that was an accessory to competition law breaches, Mr Sims said.
