According to one account, the Time Lords' archives of the Second Doctor's trial recorded its verdict as "Malfeasance Tribunal order dated 309906". (TV: The Deadly Assassin)
Indeed, other accounts concurred that it was in the Gallifreyan Year 309906 (AUDIO: Neverland, PROSE: War Crimes) that the Second Doctor summoned the Time Lords to aid with the cessation of the War Games. Subsequently, the War Lord was trialed and erased from time. Also, the Doctor was sentenced to an exile on Earth and a forced regeneration for breaking the non-interference policy, (TV: The War Games) although it was postponed for a time whilst he become the "hired gun" of the Celestial Intervention Agency. (PROSE: World Game) Also in this year, the High Council War Crimes Comission returned earlier experiments of the War Lords to their origin-points, causing trouble when Ossu was returned to the Ulk-Ra planet. (PROSE: War Crimes)
However, other accounts treated the figure as a reference number for the trial itself rather than a date, speaking of "Malfeasance Tribunal 309906" (PROSE: A Brief History of Time Lords) or "Malfeasance Tribunal order 30906". (PROSE: Doctor Who and the Deadly Assassin)
