Misra joined the Justice for Subpostmasters Alliance (JFSA) group that had been set up by
Alan Bates in 2009. Her story was featured on a
Panorama programme on the Post Office scandal, broadcast on 17 August 2017. Misra was one of the 555 subpostmasters who joined the group legal action of
Bates & Others v Post Office Ltd, heard by
Justice Fraser in the
High Court at the
Rolls Building in London between 2017 and 2019. After two subtrials, one of which looked at the subpostmasters' contracts and found largely in their favour and the other which found that Horizon contained
bugs, errors and defects that could lead to accounting discrepancies, the claimants had run out of funding and agreed a settlement of £56.75 million with the Post Office. Legal costs of £46 million were deducted, leaving the 555 claimants with less than £12 million to be divided between them. The settlement agreement stated that "the Defendant has not made, or agreed to make, any payment to or for the benefit of any Convicted Claimant". Misra, and the minority of claimants who likewise had convictions, therefore received only a small payment thanks to the generosity of their fellow claimants. The case, however, would open the way for those convicted to pursue the Post Office for malicious prosecution and gain larger sums of compensation. On 26 March 2020, following the judgment in
Bates & Others v Post Office Ltd, the
Criminal Cases Review Commission referred Misra's case, along with those of 38 other convicted subpostmasters, to the
Court of Appeal. Misra featured in a second
Panorama programme on the Post Office scandal, broadcast on 8 June 2020. The programme revealed that the Post Office legal department were told about Horizon errors shortly before her trial, but failed to disclose the material to Misra's defence team. By the time the appeal,
Hamilton & Others v Post Office Limited, came to court in March 2021 there was a total of 42 appellants. Misra and two other appellants were represented by barristers Paul Marshall and Flora Page. On 23 April 2021, Misra and 38 other subpostmasters officially had their convictions quashed and their names cleared as the judgment was handed down at the
Royal Courts of Justice. The Court of Appeal also decided that their prosecutions had been an affront to justice.
Lord Justice Holroyde said that the Post Office had "consistently asserted that Horizon was robust and reliable", even though they were aware that it was not reliable, and "effectively steamrolled over any sub-postmaster who sought to challenge its accuracy". == Horizon IT Inquiry ==
