UK Home Office Visa 'Streaming Tool' — Nationality-Based Risk Triage Withdrawn After Legal Challenge

The Home Office used a 'streaming tool' to sort visa applications into red, amber and green categories before a caseworker saw them. Red applications needed more scrutiny and senior sign-off; according to figures cited in the litigation, about 99.5% of green applications succeeded against 48.59% of red ones. Nationality was one of the factors used, and a confidential list of 'suspect' nationalities, produced through an Equality Act nationality risk assessment, automatically drove higher-risk ratings.
The Joint Council for the Welfare of Immigrants, represented by the non-profit Foxglove, brought judicial review proceedings in 2020 arguing the tool was discriminatory under the Equality Act 2010 and irrational at common law. A central concern was a feedback loop: refusals counted as adverse events, so nationalities with high refusal rates stayed flagged. In a letter of 3 August 2020 the Government Legal Department said the tool would stop being used from 7 August pending a redesign, to be completed by the end of October 2020.
The Home Office stated that the redesign did not mean it accepted the allegations. It committed to an interim process based on person-centric attributes rather than nationality, and to completing a data protection impact assessment. The case is included as a cautionary example: an opaque triage model was only exposed through litigation, with no published accuracy or equality evaluation beforehand.
