Justice Justine Thornton

Justice Justine Thornton presided over the high-profile corruption trial of former Nigerian Petroleum Minister Diezani Alison-Madueke at Southwark Crown Court in London during 2026. The case represented one of the most significant prosecutions of a former Nigerian official in British courts, with Alison-Madueke facing multiple charges related to money laundering and bribery allegedly committed during her tenure as petroleum minister from 2010 to 2015. Justice Thornton guided the complex proceedings through months of testimony and evidence presentation.

The trial stemmed from years of investigation into corruption in Nigeria's oil sector during the Goodluck Jonathan administration. Alison-Madueke, who had been living in the UK since leaving office, was arrested by British authorities in 2015 as part of international efforts to recover stolen Nigerian assets. The case involved collaboration between Nigerian anti-corruption agencies, British law enforcement, and international partners tracking suspicious financial transactions across multiple jurisdictions. The prosecution represented a test case for cross-border accountability mechanisms targeting high-level corruption.
