A creditor who assumes control of his debtor's business may become liable as principal for the acts of the debtor in connection with the business. Restatement (Second) of Agency § 14 O (1958). It is noted in comment a to section 14 O that: A security holder who merely exercises a veto power over the business acts of his debtor by preventing purchases or sales above specified amounts does not thereby become a principal. However, if he takes over the management of the debtor's business either in person or through an agent, and directs what contracts may or may not be made, he becomes a principal, liable as a principal for the obligations incurred thereafter in the normal course of business by the debtor who has now become his general agent. The point at which the creditor becomes a principal is that at which he assumes de facto control over the conduct of his debtor, whatever the terms of the formal contract with his debtor may be.
