Resisting deprivation proceedings
When facing deprivation you will first be asked to make submissions to the Home Office. The submissions must focus on both the reason for the proceedings – criminality or dishonesty – and also the impact that losing your citizenship will have. Generally, people inside the UK will have a stronger response than people outside the UK because the impact of losing their citizenship will be greater.
To resist proceedings based on criminality you will likely need to show that the criminal offending does not reach the required threshold or is otherwise mitigated by circumstances of the offence or the strength of your ties to and life in the UK.
To resist dishonesty based proceedings you might need to show you were not dishonest, that the dishonesty had no impact at all on the grant of citizenship or that the dishonesty was of such insignificance that losing your citizenship is a disproportionately harsh response.
In any case, detailed evidence and careful preparation will be required including witness statements from you and any who can support you.
If the Home Office do not accept the submissions, you will receive a deprivation (or nullity) decision which can be appealed. If you appeal, and you should, the same submissions can be made to a Judge. The Judge will weigh any mitigating circumstances against the public interest raised by the Home Office.
