Immigration – Refusal of leave. The claimants sought judicial review of the transmission of information under the immigration sanction scheme which could be imposed on non-residents seeking to enter or to remain in the United Kingdom who had unpaid NHS debts of at least £1,000. The Administrative Court, in dismissing the application, held that the relevant information was not confidential, and that the Secretary of State had both the statutory and common law duties to transmit the information. Further, the NHS bodies had had a duty, not a discretion, to transmit the relevant information to the Secretary of State.
