withdrew in 1955 the retiring partner had called on but one, that solicitation had been conducted by a staff of four salesmen who gave “good coverage,” and that any competent group of hired salesmen could have performed the tasks involved. A further consideration is that since the partnership was never indebted in any amount to the defendant, extension of credit is not a factor.
We agree with plaintiff’s conclusion that he should be allowed to go to trial on the issue of whether he could carry on this sales agency contract as the surviving partner, but for different reasons. This contract creates an agency and therefore we think that it is necessarily personal in nature. Duties under a personal contract are delegable, however, if the obligee or principal can be said from all the circumstances to have assented to such delegation.
The personal nature of an agency contract arises as an incident of the legal relationship. An agent may be an independent contractor, not subject to control in the manner in which he performs his duties, but he is an agent nevertheless, and from this agency relation flow certain legal consequences. The fact of the relation implies a promise to use care and skill and imposes fiduciary obligations of loyalty and obedience not normally present in other bilateral agreements. See Commonwealth v. Minds Coal Mining Corp., 1948, 360 Pa. 7, 60 A.2d 14. Because in fact the agency relationship is normally grounded •on the trust and confidence the principal places in his agent, the law has come to impose these personal obligations and duties of the agent and to look upon the relationship as being personal in nature as a matter of law. As a consequence agency duties ordinarily cannot be delegated by the assignment of the contract without the express or implied authority of the principal, see Wetherell Bros. Co. v. United States Steel Co., 1 Cir., 1952, 200 F.2d 761; 4 Corbin, Contracts, § 865 (1951); 10 A.L.R. 653, or by the substitution of another, where the duties involve any personal discretion, skill or judgment. See
Brown v. Mt. Holly Nat. Bank, 1927, 288 Pa. 478, 136 A. 773; Restatement, Agency, § 78 (1933).
Since attempts to delegate the duties of a contractual agency have generally arisen in situations where a party has sought, as here, to continue the contract after dissolution of a partnership, the prohibition against delegation has often been phrased in terms of the proposition that the dissolution of a partnership acting as an agent terminates the agency. See Egner v. States Realty Co., 1947, 223 Minn. 305, 26 N.W.2d 464, 170 A.L.R. 500, 512; Meysenburg v. Littlefield, C.C.E.D.Mo., 1905, 135 F. 184; 40 Am.Jur., Partnership, § 267. But we cannot agree that this proposition of law should govern all cases, and we are of the opinion that it should not control here.
It is one thing to say that an agency contract is personal in nature and that agency duties ordinarily cannot be delegated even to a competent substitute without the express or implied authority of the principal. It is another thing to say that the withdrawal of a partner terminates all partnership agency contracts. The latter proposition depends on the view that withdrawal of a partner dissolves the partnership and that therefore any organization resulting from the dissolution is as much a stranger to the principal as an organization completely unrelated to the prior partnership. We think such a conclusion unwarranted and unrealistic. Indeed, courts which have held that dissolution terminates the agency have generally done so only after a careful development and analysis of the facts which indicated that the assignee was in fact substantially different from the prior agent. See e. g. Egner v. States Realty Co., supra; Paige v. Faure, 1920, 229 N.Y. 114, 127 N.E. 898, 10 A.L.R. 649.
Delegation of duties is proper if the principal authorizes, expressly or by implication, the performance by another. Thus there is an implied authorization to delegate ministerial duties or those generally understood to be dele-
