As per the Central Industrial Security Force Act and Rules, disciplinary punishments can be awarded to enrolled members. Minor punishments listed often include duties like ‘Drill’, ‘extra guard’, and ‘fatigue duty’. These are considered legitimate disciplinary measures within the force.
Minor punishments like extra drill, guard, or fatigue are standard in uniformed forces.
Article 311 of the Constitution provides safeguards for civil servants but does not grant complete exemption from disciplinary action for members of uniformed forces (A). Members typically have rights to appeal and potentially seek revision against punishment orders (C is likely incorrect). While the Central Administrative Tribunal (CAT) is an avenue for redressal, it might not be the *only* remedy (D is likely incorrect).
