Single Judge bench of Manipur High Court held as follows:
From Para 4,
 Although it is nowhere mentioned in the application that the same has been filed under the provisions of CPC, it is the provisions of Order 3 Rule 4(2) of CPC which provide that appointment of an Advocate shall be filed in the court and shall be deemed to be in force until determined with the leave of the court by a writing signed by the client or the Advocate as the case may be. An Advocate does not only represent his client but he is also an officer of the court. In any matter in which he is engaged, he has to assist the court till his vakalatnama is determined in accordance with law.
From Para 6,
Ashem Shyamkesho Singh Vs Thokchom Ranjan Meetei on 08 Jul 2016
The normal conduct of a client is that if he wishes to change his counsel for some reason or the other, he should approach him for return of the brief and to obtain “No Objection” from him. In case his counsel returns the brief, it is well and good and if he refuses to return the brief or refuses to give “No Objection”, the client may invoke the provisions of Order 3 Rule 4 of the CPC to redress his grievances. However, in the present case, the applicants have failed to that and without determining the appointment of their earlier counsel, Shri Ng. Kumar, Advocate, they had moved an application for deleting their names from the array of parties in the writ petition through another Advocate which is unfair and unreasonable on the part of the applicants. The moment an Advocate is engaged, a client is expected to be fair and reasonable to him and ought to give proper instructions accordingly. But in any case and for whatever reasons, the applicants have expressed their view that they don’t want Shri Ng. Kumar, Advocate to continue as their counsel and that a new Advocate be engaged in his place and since the Hon’ble Supreme Court in the said R.D. Saxena’s Case (supra) has categorically observed that for whatever reason, if a client does not want to continue the engagement of a particular Advocate, it would be a professional requirement consistent with the dignity of the profession that he would return the brief to the client and it is time to hold that such obligation is not only a legal duty but a moral imperative, this court is of the view that this application is liable to be allowed. In view of the above observations of the Hon’ble Supreme Court, it is the duty of Shri Ng. Kumar, Advocate to give “No Objection” so that the applicants could engage a new Advocate of their choice. If Shri Ng. Kumar, Advocate is of the view that the action of the applicants being unfair and unreasonable, has caused prejudice to his professional right and privilege as a counsel, it is open to him to seek appropriate relief and redress his grievance from an appropriate forum.
