Britain’s High Court rules on an appeal brought by five people who entered the country via the Channel. The claimants argue that the Government’s “one-in, one-out” approach for handling people who cross the Channel unlawfully affected their deportation decisions. Multiple reports say the court backs the migrants’ legal challenge, finding that the Government is not acting lawfully in the way it applies the policy to deportations. The decision is described as a significant setback for Home Office plans associated with the scheme, which have been linked to former or current Home Office decision-making under the “one-in, one-out” framework. The ruling addresses the legality of how deportation outcomes are determined under the policy, rather than claims about the migrants’ broader immigration status alone. The Government’s next steps, including whether it will seek further appeal or revise the policy’s operation in response to the judgment, are not detailed in the provided summaries.
