ACCC v Coles Group Limited
 FCA 363 (14 April 2014)
ACCC v Woolworths Limited
 FCA 364 (14 April 2014)
Justice Robertson in the Federal Court found Woolworths breached its undertaking on fuel shopper dockets from January - March 2014, because its 8 cents per litre discount was contingent on acquiring Woolworths supermarket goods or services. Coles, on the other hand, was found not to have breached their agreement, because the higher discounts were funded primarily though Coles Express stores.
