216.Section 73 makes provision for cases where a person has appealed and that appeal has been finally determined, but there has been a further decision, against which a notice of appeal has been lodged. Subsections (2) and (3) provide that the Secretary of State may certify a human rights claim made in such a notice to the effect that it could reasonably have been made before, is designed to delay removal and has no other legitimate purpose. On certification the human rights aspect of the appeal is to be treated as finally determined.
217.Subsections (4) and (5) prevent a person from pursuing an appeal based on matters which were considered at the earlier appeal, if the Secretary of State certifies that they were so considered.
218.Subsections (7) to (9) effectively allow an immigration officer or the Secretary of State to certify that a further application is being made to delay removal and for no other legitimate purpose; if certified, no appeal can be brought.
