You work at a firm and your supervisor has asked you to review six contracts and determine the type of each contract, research the key elements of contracts and assess their validity.

Check the applicable remedies in each of the scenarios and give the reason why they would be the best course of action. You will need to include relevant case law in your answer to support your reasoning.(Please apply Australian Law/legal system). You will need to apply principles of contract law at the next meeting.

You MUST apply each element to the scenario.

Scenario 1 - Mrs. Jones and the Cake

Mrs Jones rings her baker and orders a cake for a birthday party she is having that evening. The baker promises to deliver them later that afternoon. She pays a deposit.

John puts an advert on an online marketplace stating that he wants to sell his car for $5000. Anthony sees the advert and contacts John for his address. He drives to see the car and after inspecting it, hands him the money.

John accepts the money and says "Congratulations, hope you enjoy the car!" when Steve pulls up at John's home. John had forgotten that he had Steve scheduled to view the car.

Steve gets angry and tells John that he shouldn't have sold the car because they had a verbal agreement.

Scenario 3 - Ben and Andy's Pool

Ben and Andy put up their house for sale and a buyer shows up to the open house. The buyer notices a pool and asks if they have a safety certificate attached. Andy turns to Ben and the buyer and says "I'm sure we do, we'll send it later."

After the open house the buyer puts an offer in and asks for a safety of the pool certificate. Ben and Andy realise that there is no pool certificate and lets the buyer know after they accept the offer. The buyer then withdraws their offer immediately as a result. Ben and Andy call the buyer two days later and say that he can't change his mind because they've already accepted the offer.

Scenario 4 - Ryan and Bailey's Pub Agreement

I'd love to sell to my best friend!"

The next day, Bailey's solicitor sends an email to Ryan with details of the sale. Ryan realises what he's done and calls Bailey to let him know that he wasn't thinking when he accepted the offer. He would like to withdraw. Bailey insists the contract is valid as he declared it to the whole pub.
