PRINCIPAL'S RIGHT AND POWER TO REVOKE DISTIN GUISHED. While the principal has the power to re voke any agency, at will, save those coupled with an interest, it does not follow that in every such case he has such an unqualified right to revoke as will release him from liability to the agent for so doing. The power to revoke is broader than the right to revoke without liability.
Thus if there is an agreement between the principal and his agent, that the agency shall continue for a definite period of time, or until the happening of some event, it cannot be rightfully terminated by the princi pal otherwise than as stipulated, unless for good cause, such as misconduct on the part of the agent. And for revocation, except for good cause, he is liable in dam ages to the agent as for the breach of any other con tract. (Mechem on Agency, Sec. 210.) In the absence of such special agreement, express or implied, the bare power given an agent by the princi pal may be revoked at the will of the principal without incurring any liability to the agent. So if the agree ment is to the effect that the agency shall continue so long as the parties are satisfied, it may be terminated without liability. (Kirk v. Hartman, 63 Pa. St. 97; Adriance v. Rutherford, 57 Mich. I70.)
