Chelvan litigates, and provides advice on strategic litigation, from the First-tier Tribunal (Immigration and Asylum Chamber), up to and including the UK Supreme Court and the European Courts. Known as ‘a tenacious battler who fights with vigour and commitment’ (Legal 500), Chelvan has a practice which spans the entire spectrum of immigration, asylum and nationality law, which is at the forefront of cutting edge litigation in the field. He provides advice, where the need arises, in the pre-application stage, to ensure that if litigation occurs, then his clients start from a position of strength. His clients range from the individual asylum seeker, to large scale businesses and educational institutions, caught within the quagmire of increasingly confusing immigration rules and potentially obstructive legislation. His international work not only includes litigation, but also encompasses advisory work with practitioners, academics, the judiciary, UNHCR, NGOs, the media and governments.
