Can changing the lawyer's authorization revoke the lawyer's litigation behavior?

Changing the lawyer's authorization can revoke the lawyer's litigation behavior. According to the relevant public information, if the parties change the lawyer's authorization and withdraw the original authorized lawyer's agency right, the court shall notify the original agent in time after receiving the withdrawal notice and suspend the agent's litigation behavior. The change or revocation of authorization by the parties does not mean the cancellation of the lawyer's existing litigation behavior. The relevant legal acts that lawyers have carried out are still valid according to legal procedures, and newly authorized lawyers or parties need to continue to handle relevant cases on their own.
