As per case facts, petitioners, who are Head Constables, sought direction to be deputed for the Intermediate School Course, having been denied selection despite their eligibility, allegedly due to past ... punishments like forfeiture of increment. The respondents, relying on WAN messages, stated that officials facing punishment would not be deputed. The petitioners contended that the course enlistment is not part of promotion and Rule 13.9 of PPR does not prescribe such eligibility criteria, citing a Full Bench judgment that grants a right to attend based on seniority. The question arose whether clarifications issued by an officer in the form of WAN messages, which made petitioners ineligible due to past punishment, were legally binding and consistent with Police Rules and judicial pronouncements. Finally, the High Court ruled that the WAN messages were issued without proper authority and contradicted established legal interpretations of Rule 13.9 of PPR. The Court held that the DGP's actions were beyond jurisdiction and amounted to an impermissible amendment of the Rules. Consequently, the petitioners are eligible based on seniority and must be deputed for the Intermediate School Course, with the instruction that they be deemed to have passed the course if not deputed for the ongoing session.
