It had been almost five months since her appeal was admitted by the High Court but the hearing had not yet started. The prosecution was yet to file its appeal, and the hearing would take long to complete. The trial itself had taken ten years, it points out.
The petition also claims that she was not "a flight risk" as she was living in the city for many years with "deep roots in the society" and had been a gynaecology practitioner.
