Commentary on Sections Applications Section 120: Requirement to state additional grounds for application
287.Section 120 replaces and extends the application of the one-stop notice in section 75 of the 1999 Act. There is now no limitation on the category of applicant on whom the requirement to state grounds for application and the “one-stop warning” can be served and IND has the operational freedom to serve it at any appropriate point in the process.
288.Subsection (1) applies the section to people who have made an application to enter or remain in the United Kingdom and to people in respect of whom a relevant decision has been or may be taken without an application being made: for example where it is proposed to remove someone as an illegal entrant.
289.Subsection (2) states that when served with a "notice in writing" the person is required to state all his reasons for wishing to enter or remain in the UK, and any grounds on which IND should be obliged to let him enter or remain here, and any grounds on which he should not be removed. If he does not do so, any attempt to raise such grounds later on may lead to certification under section 96 with the effect that there can be no appeal against the decision, or that those grounds cannot be raised in connection with a further appeal.
290.Subsection (3) indicates that a statement made in response to a requirement and one-stop warning does not have to repeat what the applicant has already said in his application.
