Johannesburg Fuel Corp. hired Bobco Contractors to clean up their work yard, which was twice as large as Bobco first thought it would be, in Albany, New York on April 7th, prepatory to selling their entire plan and real property to Axelrod Industries on May 10th. Johannesburg also contracted to sell it's inventory of 50,000 widgets to Constant Machines Inc. Earlier, Johannesburg has leased this plant to Peterbilt for a period of one yeat, and required Gary Allen, a local investor who also got use of the plant, to pay the rent on the lease if Peterbilt did not. Which of these contracts had to be in writing to be enforceable? If the price of the widgets went up three times, or were unavailable anywhere in the world, after the contract was formed, could that contract be avoided by either party in either case? If each contract had a Parol Evidence Integration clause, what oral evidence, if any, could be heard in court as to each contract? Cna any oarty here likely use fraud, mutual mistake or duress as a contract defense? Is any party here a third party beneficiary? Has any novation occurred here? Explain.
