What is the process of refusal of registration?

In case registration is refused, the applicant will be
informed about the reasons for such refusal through a
speaking order. The applicant shall have the right to appeal
against the decision of the Authority. As per sub-section
(10) of section 19 of MGL, any rejection of application for
registration by one authority (i.e. under the CGST Act /
SGST Act) shall be deemed to be a rejection of application
for registration by the other tax authority (i.e. under the
SGST Act / CGST Act).
