These Articles 142, Constitution etc. appear to be been reduced to just a matter of books if one reads things happening like these:

Since her arrest last October, Sori has alleged that she was brutally beaten, s*xually assaulted and administered electric shocks in custody. The police officer she accuses was given a gallantry award on Republic Day. Earlier, her ageing father was shot in the leg by Maoists, while her husband was arrested for being an alleged Maoist.

Six months on, a PIL filed on her behalf is yet to be heard in the Supreme Court. Last October, an independent medical examination ordered by the apex court discovered stones from Sori’s v**gina and rectum (Shockingly, Soni Sori has been s*xually tortured with stones. Who will answer for this? by Tusha Mittal, 24 December 2011). This report was discussed in the court on 2 December. Shockingly, the court allowed the Chhattisgarh government more than a month to respond. The next hearing was scheduled for 25 January. Sori’s case was listed as item 14. But it never came up.

Alerting the court of her worsening medical condition, Sori’s lawyers filed two separate appeals for an urgent hearing. They received no response. The case was rescheduled for 2 February, but wasn’t heard again. Since then, Sori’s case has been listed for hearing thrice a week in the court of Justice Altamas Kabir.
