Fundamental Rights
(1) Traffic in human beings and begar and other similar forms of forced labour are prohibited and any contravention of this provision shall be an offence punishable in accordance with law. (2) Nothing in this article shall prevent the State from imposing compulsory service for public purposes, and in imposing such service the State shall not make any discrimination on grounds only of religion, race, caste or class or any of them.
Human trafficking, "begar" (forced unpaid labour), and similar forms of forced labour are completely prohibited and criminally punishable - this right applies against private individuals and organisations, not just the government. The government can still require compulsory service for genuinely public purposes (like certain forms of national service), but it must apply that requirement without discrimination.
A worker being forced to labour without pay to "pay off" a debt (bonded labour), or someone trafficked and forced into labour or exploitation, can invoke Article 23 directly - this is reinforced by BNS Section 143 (Trafficking of Person) and the Bonded Labour System (Abolition) Act, 1976.
