- Under the foot SUB POTESTATE.-Under power; subject to the power of another; as a slave, wife, or child. 1. When an agent employs a person as his agent, to assist him in transacting the affairs of his principal, the person so employed is called a "sub-agent." In the absence of an agreement to the contrary, there is no privity between the principal of the seal. and the sub-agent; therefore, the principal is not liable to the sub-agent for his remuneration, and he cannot sue the subagent for negligence or misconduct; he must sue the agent. (See Russ. Merc. Ag. 210.) But if the agent has an express or implied authority to employ a sub-agent, privity of contract arises between the principal and the sub-agent, and the principal may sue the sub-agent for misconduct. De Bussche v. Alt, 8 Ch. D. 287. 2. Similarly, when a contractor makes a contract with a sub-contractor to carry out his contract, or part of it, there is no privity between the principal contractee and the sub-contractor. (Goslin v. Agricultural Hall Co., 1 C. P. D. 482.) As to the relations between a contractor and his servants, and between the latter and the contractor's principal, see Woolley v. Metr. D. Ry. Co., 2 Ex. D. 384; Pearson v. Cox, 2 C. P. D. 369. SUB SIGILLO.-Under seal.
