Immigration – Leave to remain. The claimant Nigerian national sought judicial review of the defendant Secretary of State's decision, refusing her leave to remain in the United Kingdom. The Administrative Court, in dismissing the application, held that the Secretary of State had not taken into account letters from the claimant's mother and grandmother. However, there was nothing in the application which set out what, if any, links there were with Nigeria or the lack of them and the assessment of the claimant's ties to Nigeria would have produced exactly the same result. Accordingly, the error had not been a material one such as would justify the quashing of the decision.
