Question

Alan’s Saddles makes high level seats for racing bicycles and sells to many of the top bicycle manufacturers. There are eight available sources of the type of rubber that Alan’s uses; however, they have always dealt with a company in the Republic of Anaerobia exclusively. Your company has a contract with Alan’s for 10,000 seats. You have just received a letter from Alan’s explaining that due to turmoil in Anaerobia, their supplier cannot export their product so Alan’s cannot complete the contract

Answer 1

Your company can sue for breach because if the raw materials are reasonably available from another source, Alan's cannot be discharged due to impracticality.

The contract has not specified that Alan's company had to get the materials exclusively from Republic of Anaerobia, if he had specified that, there would be no problem at all.
