If you receive an appeal from a claimant who
follow the guidance at CCOM21500 and remind them of their
earlier agreement and invite them to withdraw their appeal.
If they have provided new information or they refuse to
withdraw the appeal you should review the grounds of the appeal to
decide if you can revise your decision, see
CCM17550.
If the claimant(s) appeals against your decision and they
did not previously agree HMRC’s information you should review
the grounds of the appeal to decide if you can revise your
decision, see
CCM17550.
