"Article 17 is one of the few Fundamental Rights enforceable against private individuals." Discuss the constitutional and jurisprudential significance of this horizontal application in the context of contemporary caste-based practices.

Article 17 declares that "untouchability" is abolished and its practice "in any form" forbidden, making enforcement of any resulting disability a punishable offence [1]. Unlike most Fundamental Rights, which restrain the State, it binds every private person — a deliberate constitutional choice, since untouchability was practised by society, not government.

Constitutional significance

• Horizontal enforceability: the prohibition operates against individuals, castes and private organisations; a citizen may seek remedy against a fellow citizen, not only the State [1].
• Absolute and unqualified: Article 17 carries no reasonable restrictions and no exceptions for custom, religion or tradition — unusual among Part III rights [1].
• Self-executing plus statutory backing: Parliament gave it teeth through the Untouchability (Offences) Act, 1955, renamed the Protection of Civil Rights Act by the 1976 amendment, which defines "civil rights" as rights accruing from the abolition of untouchability [2].
• Complements Article 15(2), which similarly bars private denial of access to shops, wells and public places.

Jurisprudential significance

• The Constitution does not define "untouchability" [1]; its content has been built by statute and judicial reading, keeping the term open to evolving forms of exclusion.
• The PCR Act translates the right into concrete offences — denial of access to shops, hotels, wells, tanks, bathing ghats and State-funded roads [2] — while the SC/ST (Prevention of Atrocities) Act, 1989 adds a stringent parallel regime for caste humiliation [3].

Contemporary caste-based practices

• Exclusion today is often symbolic rather than physical: the 2026 Haldwani "shuddhikaran" row, where a venue was ritually "purified" after a Dalit leader's rally, raised whether purification without denial of entry is untouchability [4].
• Purity–pollution logic persists in manual scavenging, segregated crockery and separate settlements.

Article 17's horizontal reach makes constitutional morality binding on society itself. The way forward lies in vigorous PCR Act enforcement, sensitised policing, and judicial interpretation that reads "in any form" purposively — so that dignity under Article 21 becomes lived reality, not merely declared.
