Section 19 in The Trade Marks Act, 1999

19. Withdrawal of Acceptance —
Where, after the acceptance of an application for registration of a trademark but before its registration, the Registrar is satisfied—

(a) that the application has been accepted in error; or

(b) that in the circumstances of the case the trade mark should not be registered or should be registered subject to conditions or limitations or to conditions additional to or different from the conditions or limitations subject to which the application has been accepted, the Registrar may, after hearing the applicant if he so desires, withdraw the acceptance and proceed as if the application had not been accepted.

Hearing of Trademark under section 57 of the Trade Marks Act, 1999 –

Section 57 in The Trade Marks Act, 1999

57. Power to cancel or vary registration and to rectify the register.—

(1) On application made in the prescribed manner to the Appellate Board or to the Registrar by any person aggrieved, the tribunal may make such order as it may think fit for cancelling or varying the registration of a trade mark on the ground of any contravention, or failure to observe a condition entered on the register in relation thereto.

(2) Any person aggrieved by the absence or omission from the register of any entry, or by any entry made in the register without sufficient cause, or by any entry wrongly remaining on the register, or by any error or defect in any entry in the register, may apply in the prescribed manner to the Appellate Board or to the Registrar, and the tribunal may make such order for making, expunging or varying the entry as it may think fit.

(3) The tribunal may in any proceeding under this section decide any question that may be necessary or expedient to decide in connection with the rectification of the register.

(4) The tribunal, of its own motion, may, after giving notice in the prescribed manner to the parties concerned and after giving them an opportunity of being heard, make any order referred to in sub-section (1) or sub-section (2).
(5) Any order of the Appellate Board rectifying the register shall direct that notice of the rectification shall be served upon the Registrar in the prescribed manner who shall upon receipt of such notice rectify the register accordingly.

Above is the legal provision to deal with the certain situation in a trademark. Once a trademark is granted its registration after completion of the due process, the Registrar of the Trademarks has no powers to intervene into. But, in a few cases where the due process of law is overlooked and the grant of the Trademark is done with apparent flaws, overlooking/overriding the legal provisions, under the situation, the Act provides specific powers to the Registrar to look into the matter and pass such an appropriate orders and rectify the register in public interest and to come in the line of the Law.

Section 19 provides a narrow escape to the applicant. Sec.19 gives no scope / power to the Registrar, but Sec.57 gives a full authority to the Registrar on its own without intervention of the user.
