How does Article 926 of the Civil Code explain the client's right of intervention and the third party's right of choice?

Explanation: The interference right of the principal refers to that in the contractual relationship between the trustee and the third party, the principal replaces the position of the trustee and intervenes in the contractual relationship between the trustee and the third party. The conditions for the principal to exercise the right of intervention are as follows: first, the agent enters into a contract with a third party in his own name. Where an agent enters into a contract with a third party in the name of the principal, the contract is originally directly binding on the principal and the third party, and the provisions of this article are not applicable.
