There may also be circumstances where, irrespective of the facilities available, the specific situation or special needs of applicants would in any event preclude them from being admitted or from remaining in a border procedure. In this context, a border procedure should not be applied, or should cease to apply, where necessary support cannot be provided to applicants in need of special procedural guarantees or where justified on health grounds, including reasons pertaining to a person’s mental health. Equally, having regard to the importance of the rights of the child and the need to take into account the best interests of the child, unaccompanied minors should not, as a rule, be subject to the border procedure unless there are reasonable grounds to consider the minor represents a danger to the national security or public order of the Member State or the applicant had been forcibly expelled for serious reasons of national security or public order under national law.
