1. John entered into a 2 year agreement with the Blue Mountains City Council to lease a café at a popular National Park scenic spot famous for its views overlooking the Grose Valley. The café was very successful but after 6 months a sewerage disposal works was set up near the café. Business suffers badly and after seeing his customers decrease rapidly John leaves the business and refuses to pay any further rent. The Council sues. Discuss. Also, is there any further evidence that may make your decision as to the outcome any clearer?
