Thanks for immediate feed back. It may happen in certain situation that engaged avd may give oral instructions to third adv to plead in the matter on behalf of the client and client may or may not present. This third advocate makes grave mistake in pleading and on next hearing engaged adv may disown the liability to avoid the damage. There may be another situation wherein the third avdvocate may plead without instruction from the the advocate engaged, to damage/improve the case. In these two situations how the court and apposite party should react? In both of these two situations there would nothing on record to show that particular third adv acted either under the authority of the third party or suo moto. Further how would it be proved that particular third adv. pleaded? What would be the status of the validity of the proceeding happened in that these situations?
