Operating out of an apartment in Secane, Pennsylvania, Hratch Ilanjian convinced Vicken Setrakian, the president of Kenset Corp., that he was an international businessman who could help Kenset turn around its business in the Middle East. At Ilanjian's insistence, Setrakian provided confidential business documents. Claiming that they had an agreement, Ilanjian demanded full, immediate payment and threatened to disclose the confidential information to a Kenset supplier if payment was not forthcoming. Kenset denied that they had a contract and filed a suit in a federal district court against Ilanjian, seeking return of the documents. During discovery, Ilanjian was uncooperative. Who behaved unethically in these circumstances? Explain.
