On 13 October 2011, Dr. Andrew Reid, the Coroner of St. Pancras, announced that he would hold an inquest into Litvinenko's death, which would include the examination of all existing theories of the murder, including possible complicity of the Russian government. The inquest, held by Sir Robert Owen, a High Court judge acting as the coroner, originally scheduled to start on 1 May 2013, was subject to a series of pre-hearings: firstly, the coroner agreed that a group representing Russian state prosecutors could be accepted as a party to the inquest process; secondly, the British Government submitted a Public Interest Immunity (PII) certificate. Under Public Interest Immunity (PII) claims, the information at the disposal of the British government relating to Russian state involvement, as well as how much British intelligence services could have done to prevent the death, would be excluded from the inquest.
