An agent, unless specially forbidden by his principal to do so, can delegate his powers to another person in any of the following cases, and in no others:
1. When the act to be done is purely mechanical;
2. When it is such as the agent cannot himself, and the sub-agent can lawfully perform;
3. When it is the usage of the place to delegate such powers; or,
4. When such delegation is specially authorized by the
principal.
(Enacted 1872.)
If an agent employs a sub-agent without authority, the former is a principal and the latter his agent, and the principal of the former has no connection with the latter.
(Enacted 1872.)
A sub-agent, lawfully appointed, represents the principal in like manner with the original agent; and the original agent is not responsible to third persons for the acts of the sub-agent.
