QUESTION 1

Betty contracted with Roger the Dodger Home Decorating Pty Ltd to redesign the interiors of her whole house and complete the job in 3 months for $ 100,000. The job was completed on time, but about 25 % of it was not finished properly with quite a few faults and it would cost another $ 20,000 to finish it off properly. Betty refuses to pay anything to Rodger the Dodger who is demanding payment because he says he completed the job on time.

Discuss the legal situation for both parties with reference to any relevant cases.
