UK High Court Rules Home Office Trafficking Guidance Unlawful
7/10/2026, 10:43:21 PM
Core Event
On 10 July 2026, London’s High Court held that a September 2025 amendment to Home Office guidance was unlawful. The guidance had barred asylum seekers deemed “not a victim of trafficking” from challenging that determination before removal under the United Kingdom’s “one-in, one-out” agreement with France. The court found the change violated the right of affected individuals to contest the decision.
Background & Context
The “one-in, one-out” deal, introduced in August 2025, obliges the UK to return a person who arrives in a small boat from France in exchange for accepting a migrant who arrives through a regular route. By the time of the judgment, 921 small-boat migrants had been sent back to France—about 3.5 % of all such arrivals—and the UK had accepted 896 migrants from France. In September 2025 Home Secretary Shabana Mahmood altered the Home Office’s trafficking-victim assessment guidance to prevent “last-minute modern slavery claims” from delaying removals.
Key Figures & Groups
- Mr Justice Clive Sheldon – the presiding judge who issued the 115-page judgment.
- Home Office – the interior ministry responsible for the guidance and for implementing the bilateral removal scheme.
- Shabana Mahmood – the Labour Home Secretary who approved the guidance change.
- Five unnamed asylum seekers – the claimants who challenged the guidance after being removed or facing removal to France.
Data & Statistics
- In 2025, 79 % of individuals initially classified as “not a victim of trafficking” were later granted a positive decision on reconsideration.
- Since the scheme’s launch, 921 small-boat migrants have been returned to France, representing 3.5 % of all small-boat arrivals.
- During the same period, the UK accepted 896 migrants from France.
Why It Matters
The ruling curtails the government’s ability to expedite removals by sidelining trafficking-victim assessments, marking a setback for the Labour administration’s broader effort to tighten immigration controls. It also raises concerns that genuine trafficking victims could be missed when decisions are made within five working days, often without adequate medical or linguistic support.
Official Statements & Responses
The Home Office announced it will appeal, with a spokesperson stating, “Last-minute modern slavery claims must not be used to frustrate the removal of illegal migrants.” Labour officials described the judgment as a “significant legal defeat” but affirmed their commitment to reforming the law while safeguarding genuine victims. Lawyers for the claimants welcomed the decision, noting that many individuals had already been removed to France unlawfully.
Criticism & Opposition
Representing the claimants, counsel argued that the policy “sacrifices fundamental rights for the sake of expediency and speed of decision-making.” The judgment itself described the amended process as “not robust and effective” and outside Parliament’s contemplation, echoing broader criticism that the rapid assessment framework fails to capture complex trafficking evidence.
On-the-Ground Reports
One claimant, who was returned to France, described a “feeling of hopelessness” and said, “When a lot of individuals enter the United Kingdom to seek refuge…being further mistreated is simply heart-breaking.” The same individual added, “Some people they place in hotels, some they return to France, like me.”
Conflicting Reports & Gaps
While the court declared the guidance unlawful, it also concluded that “the majority of Home Office decisions…were lawfully made.” This juxtaposition leaves open how many removals were genuinely unlawful versus procedurally sound, a detail not fully clarified in the available reports.
