Central Government employees seeking an arms licence for self-defence may encounter issues obtaining a No Objection Certificate (NOC) from their Head of Department (HOD). While the Arms Act doesn't explicitly mandate an NOC, the Arms Rules 2016 and state police requirements, such as Delhi Police, often list it as a mandatory document for government employees. This NOC confirms employment and the absence of adverse reports. You can present a formal application with the standard NOC format to your HOD, referencing Section 13(3)(a)(i) of the Arms Act for self-protection and noting that CCS (Conduct) Rules do not prohibit lawful firearm ownership.
