The grounds for withdrawal / revocation of international protection are set out in the Immigration Rules and include: (a) the grounds for exclusion in the Refugee Convention; (b) misrepresentation of facts to obtain refugee status; and (c) being a danger to the UK. The procedure is outlined in the section on Cessation.
The legal framework for withdrawal of leave is Section 76 of the NIAA 2002. Indefinite leave (ILR) will be taken from a person or considered to have lapsed when that person:
- Is liable to deportation or administrative removal but cannot be deported or removed because of the UK’s obligations under the Refugee Convention or the ECHR (ILR is revoked);
- Has obtained leave by deception (ILR is revoked);
- Is deported from the UK (ILR is invalidated);
- Ceases to be a refugee because of their own actions (ILR is revoked);
- Remains outside of the UK for more than two years (ILR lapses).
The only appeal against a decision to take away leave is if that is accompanied by a decision to remove protection status i.e. the appeal is against the refusal of protection status.
