The Petitioner left for Canada, after a recording letter dated 27th January, 1984 which spoke of the circumstances in which she was required to leave. In June 1984 the Petitioner received a notice to show cause for disciplinary action. In response thereto she responded on 23rd July, 1984. In February, 1985, the Petitioner was informed by the Director that unless she agreed to unconditionally resign, punitive action was liable to be taken against her. The petitioner once again reiterated her request for study leave without pay on 26th March, 1985. In July 1985 the Petitioner was asked to return to India by September, failing which disciplinary action would be taken against her.
