PIL. Public Interest Litigation (PIL) is powerful legal recourse, especially to the socially voiceless and poor. At present PPN is working towards freeing women kept in prisons for undue long periods, which are not commensurate with the actual punishment they deserve for their crimes. These unfortunate undertrials, some of whom have minor children, languish in jails, simply for want of legal and financial support to bail them out. PPN is also working on finding ways and means of rehabilitating these undertrials once they are out of jail.
