Jayzam is a resident of Manila. He is also an export trader of chicks to a particular retailer in China. Over the years of his partnership with the Chinese retailer, he has accrued a total of Php 1,000,000 in liabilities. The Chinese retailer has an agent in Manila, and Jayzam has paid the agent in check for the amount of Php 1,000,000 upon demand. The check was determined to be "drawn against insufficient funds". For the amount of Php 2, the Chinese retailer assigned the credit to Cami11e, who sued Jayzam for the recovery of Php 1,000,000. Jayzam filed a motion to dismiss the suit on the ground that Cami11e was not an interested part and therefore, has no legal right to sue him. Jayzam also asserts that he had not agreed to the change in creditor.
