Navi regularly appears before the Tribunal, Administrative Court and Court of Appeal on all areas of Immigration law. He provides advice and representation on the full range of immigration law, including, asylum, nationality, deportation, entry clearance, applications for leave to remain, in particular under the Points Based System, commercial immigration, fresh claims and emergency injunctions to prevent removal. In 2009, in SE and CJ v. SSHD (CO/2093/09) he brought the first judicial review challenge to the maintenance requirements of the Points Based System, resulting in the Secretary of State for the Home Department conceding the case and granting the Claimant leave to remain as a Tier 1 (General) migrant, paving the way for similar claims to be brought by others refused leave on the same basis. In the same year, in Metwally and others v. SSHD (CO/12448/08), the Secretary of State's conceded a challenge to his policy to refuse indefinite leave to remain to family members of a person designated by the United Nations as linked to Al Quaida. In Gibson and others v. SSHD he successfully challenged the Secretary of State's decision to refuse to grant the claimants indefinite leave to remain in line with his policy DP 5/96, again resulting in the case being conceded. He has been successful in a series of judicial review challenges to the delay in the Secretary of State issuing documentation to refugees following successful appeals: Mopfu v. SSHD (CO/2278/09), Nagarajah v. SSHD (CO/9365/08) and Okwedy v. SSHD (CO/12358/2009) all resulting in the Secretary of State conceding the cases.
