11. On the second question as to whether the respondents authorities could have issued the impugned letter dated 05/05/2016 cancelling the appointment of the petitioner, without any notice, solely on the ground that the appointment of the petitioner was subject to the police verification report. The answer is an emphatic No. The petitioner was appointed by the order dated 31/12/2015 issued by the Director, Sericulture, Assam, subject to satisfactory police verification report. However before any police verification was conducted the petitioner was allowed to join his service. From the order dated 31/12/2015, it is also seen that the petitioner’s appointment was made by the Government pursuant to the recommendation of the selection committee. Since the respondent authorities had, rightly or wrongly, allowed the petitioner to join his service consequent to the order dated 31/12/2015, the respondent authorities, in the considered opinion of this Court, could not have issued the impugned order dated 05/05/2016 cancelling the appointment of the petitioner without affording any reasonable opportunity of being heard. Even otherwise, a bare perusal of the letter dated 05/05/2016 does not disclose any reason as to why the appointment of the petitioner was sought to be cancelled. Since the impugned letter dated 05/05/2016 had serious adverse repercussions on the appointment and the service of the petitioner, it was incumbent on the respondents to have issued notice to the petitioner furnishing the ground on which the appointment of the petitioner was sought to be cancelled. This mandatory recourse not having been taken by the respondent authorities, the impugned letter dated 05/05/2016, issued by the Joint Secretary to the Government of Assam, Handloom Textiles & Sericulture Department to the extent “ As regards Shri. Dusyanta Sarma Das newly appointed Junior Assistant in the Office of Superintendent of Sericulture, Golaghat, I am directed to request you to treat his appointment as cancelled ” in the considered opinion of this Court cannot stand the scrutiny of law and is liable to be struck down as void and illegal.
