s 96 Earlier right of appeal
(1) A person may not bring an appeal under section 82 against a decision (“the new decision”) if the Secretary of State or an immigration officer certifies— (a) that the person was notified of a right of appeal under that section against another ... decision (“the old decision”) (whether or not an appeal was brought and whether or not any appeal brought has been determined), (b) that the claim or application to which the new decision relates relies on a ground that could have been raised in an appeal against the old decision, and (c) that, in the opinion of the Secretary of State or the immigration officer, there is no satisfactory reason for that ground not having been raised in an appeal against the old decision. (2) A person may not bring an appeal under section 82 if the Secretary of State or an immigration officer certifies— (a) that the person has received a notice under section 120(2), (b) that the appeal relies on a ground that should have been, but has not been, raised in a statement made under section 120(2) or (5), and (c) that, in the opinion of the Secretary of State or the immigration officer, there is no satisfactory reason for that ground not having been raised in a statement under section 120(2) or (5). (4) In subsection (1) “ notified ” means notified in accordance with regulations under section 105.
