An immigration judge behind a string of controversial rulings has written dozens of articles for a pro-open borders website.

Judge Sarah Pinder, whose decisions at tribunals have sparked a backlash in recent weeks, previously wrote for Free Movement, an online publication.

She described detention centres as "truly abhorrent" following the deaths of three detainees in 2011. The website was founded by Colin Yeo, a barrister specialising in asylum cases, who has been critical of government efforts to curb illegal immigration.

Judge Pinder has made several controversial rulings including allowing a Zimbabwean paedophile to stay in Britain because he would face "hostility" back in his home country due to his sexuality.

She previously ruled that a Jamaican drug dealer should be spared deportation after being told he had a transgender child.

Together with Judge Hugo Norton-Taylor, she also quashed a council's verdict that a Sudanese migrant was an adult, despite the Home Office saying he was at least 23 with a receding hairline.

Robert Jenrick, the shadow justice secretary, said: "Judges are trusted to park their political beliefs at the door. But when a judge's open borders political views seamlessly overlap with their expansionist judicial decisions, it's hard to escape the conclusion that they have been compromised."

Richard Tice, the deputy leader of Reform UK, called for Judge Pinder to "resign or be fired".

"She simply does not agree with the concept of detention, deterrence and strong borders," he added.

Greg Smith, the Tory MP for Mid Buckinghamshire, said: "The public expect our judiciary to be independent, not peddling their own agenda."

The articles date from 2011 to 2022, with the last piece published three years after Judge Pinder's appointment to the first-tier tribunal as a part-time immigration judge in 2019. She was later appointed to the upper tribunal, which reviews first-tier decisions, in 2024.

Judge Pinder appears to have recently deleted her social media profiles, with her LinkedIn and X accounts closed within the past month.

She also criticised the Metropolitan Police and Sir Mark Rowley, now the force's commissioner, over an operation targeting foreign offenders in 2013.

It comes after a string of immigration rulings exposed where migrants or convicted foreign criminals have secured the right to remain in the UK.

Sir Keir Starmer has criticised a decision by a different judge to allow a Palestinian family to live in the UK after they applied through a scheme for Ukrainian refugees.

Yeo recently warned that Labour's new Border Security, Asylum and Immigration Bill "won't work" if it is intended to stop small boat crossings.

"Prosecuting people smugglers who never set foot on British soil is impossible," he wrote.

A spokesman for the judiciary said: "Judicial independence and impartiality are fundamental to the rule of law...Upon taking office, judges take the judicial oath where they swear to act 'without fear or favour, affection or ill will'.

"In each case, judges make decisions based on the evidence and arguments presented to them and apply the law as it stands."
