If section 95 or section 4 support is refused or withdrawn, there will usually be a right of appeal against this decision. If there is no right of appeal, the person would need to seek legal advice about whether there are grounds for a judicial review.
If section 98 emergency support is refused there is no right of appeal. Instead, a reconsideration can be requested from the Home Office and legal advice may need to be sought. There is more information on the Asylum Support Appeals project's section 98 factsheet.
The Asylum Support Appeals Project provides advice and assistance with appeals against refusals or withdrawals of asylum support.
