A prominent Ugandan High Court judge and United Nations Criminal Tribunal judge has been sentenced to more than six years in prison in the United Kingdom after being convicted of immigration fraud and modern slavery offenses in what prosecutors called a “landmark case.”
Lydia Mugambe, 49, received her sentence Friday at Oxford Crown Court following unanimous guilty verdicts on charges of conspiracy to breach UK immigration law, requiring a person to perform forced labor, and witness intimidation. She was additionally convicted by majority verdict of human trafficking for exploitation.
The case has sent shockwaves through international legal circles, with authorities describing it as particularly troubling given Mugambe’s extensive legal credentials and position of trust.
“This represents an extraordinary abuse of power from someone who should have been upholding justice, not subverting it,” said Chief Superintendent Ben Clark, Commander for Oxfordshire. “As an extremely qualified lawyer and sitting judge, there is no doubt that Mugambe knew she was committing serious offenses.”
The investigation began in February 2023 when Thames Valley Police received reports that a young Ugandan woman was being held in slave-like conditions at Mugambe’s residence in Kidlington, near Oxford, where the judge was studying at the time.
Evidence presented during the trial revealed a sophisticated scheme involving John Mugerwa, then Deputy High Commissioner at the Ugandan Embassy in London, who prosecutors say used his diplomatic position to sponsor the victim’s visa as a domestic worker for his own household. In reality, the arrangement was for the woman to work for Mugambe, who was ineligible to sponsor visas as a student in the UK.
Prosecutors described a quid pro quo arrangement between the officials, with Mugerwa facilitating the fraudulent visa in exchange for Mugambe’s assistance with a separate court case in Uganda. Despite his involvement, Mugerwa could not be charged as the Ugandan government refused to waive his diplomatic immunity.
The victim testified that Mugambe paid for her travel to Britain, where she was then forced into unpaid domestic servitude as a maid and nanny.
“The victim showed remarkable courage in coming forward,” Clark said. “This case demonstrates how modern slavery can exist even in seemingly respectable households, perpetrated by individuals occupying positions of significant authority.”
Throughout legal proceedings, Mugambe reportedly attempted to claim diplomatic immunity through her UN position, but authorities confirmed this was officially waived by the Office of the United Nations Secretary-General, allowing the prosecution to proceed.
Mugambe was appointed to Uganda’s High Court in 2013 and in 2023 became a judge for the UN International Residual Mechanism for Criminal Tribunals, which oversees cases related to war crimes committed in Rwanda and former Yugoslavia.
The case is being hailed as a significant victory in Britain’s ongoing fight against modern slavery, with police urging anyone with information about similar situations to come forward.
“This sentence sends a clear message that no one is above the law when it comes to human exploitation,” said a spokesperson for the Crown Prosecution Service. “Regardless of status or position, those who engage in modern slavery will face the full force of justice.”
