Mousumi has a very busy practice in immigration, family and regulatory law and welcomes all instructions within her expertise. She has completed her Public Access training and is happy to take on cases from lay clients in suitable matters.
Described by the Partner and Head of the Regulatory team at Blake Morgan LLP, a leading 500 tier firm, as ‘impressive’, Mousumi is the ideal choice of counsel to instruct in the field of regulatory law.
In January 2020 Mousumi accepted the position of Visiting Lecturer at Westminster University and since then has led the teaching on the module Child Protection Law and Policy for three academic years now and in September 2021 began delivering the Family Law module to third year law students. Mousumi is currently supervising an LLM student in their dissertation focused on family law: private children proceedings.
Mousumi recently completed a 14 month secondment in a Tier 1 500 ranked large law firm acting on behalf of regulatory bodies. During this time, Mousumi was involved in a number of investigations and acted as an advocate on behalf of regulatory bodies before regulatory panels and in the High Court. She is instructed in interim order extension hearings in the High Court and before regulatory panels such as the HCPC.
Mousumi is recognised as a determined and client focused advocate who specialises in advice, representation and advocacy in all areas of immigration, asylum, nationality and citizenship, bail, human trafficking, deportation and detention cases. She acts for clients from a number of countries, including Nigeria, Gambia, Ghana, Brazil, Turkey, India, Iraq and Cameroon. She is instructed to appear in courts and tribunals at all levels up to and including the Court of Appeal.
Described by one solicitor as ‘an extremely diligent advocate whose attention to detail is exemplary’ Mousumi’s ability to engage judges and opposing counsel in a respectful manner allied with the unwavering and tenacious nature of her advocacy has led to successes both at the First-tier Tribunal and Upper Tribunal Immigration and Asylum Chamber and makes her a clear choice for solicitors in challenging cases. She also has experience of representing the Secretary of State for the Home Department at the First-tier Tribunal.
