Part A:
Angela is entitled to take an action against Tony’s Pizzeria under the Australian Consumer Law, because Tony’s business use a sign, ‘we use locally grown produce for our pizza toppings’, but actually Tony used some imported tins of tomatoes and olives every week, and according to the S18 of the Australian Consumer Law, ‘prohibits a person, in trade or commerce, from engaging in misleading or deceptive conduct.’ Which mean Tony breach S18 of the ACL, because the things which Tony doing is breach with his sign.Which mean Tony breach S18 of the ACL. So, Tony’s business can be taken an action against.

Part B:
On my opinion, Angela is correct in her belief that Tony’s sign is misleading and deceptive.
