One of the stated aims behind the Bharatiya Nyaya Sanhita, 2023 was to move criminal law away from a purely punitive, imprisonment-first mindset for offences that do not involve serious violence, and to introduce community service as a recognised form of punishment for the first time in India's general penal code. Defamation, being an offence against reputation rather than an offence involving physical harm, was one of the provisions chosen to reflect this shift.
Section 356(2) accordingly gives a sentencing court a genuine spread of choices, simple imprisonment for a term that may extend to two years, or a fine, or both together, or community service as a substitute for the more traditional penalties. Keeping imprisonment and fine available alongside community service, rather than replacing one with the other, lets the court calibrate the punishment to how serious the particular instance of defamation actually is, while still signalling that reputational harm is being treated with the restorative tone the BNS wants for offences of this kind.
This also explains why the punishment could not sensibly be only a fine, since that would remove the court's discretion in more serious instances, nor rigorous imprisonment for five years, since that treats defamation on par with far graver offences than the law intends, nor a mere apology in open court, since that has never been enacted as a formal statutory penalty.
