I was refused a job in a private company because of my religion, can I challenge this as a violation of my constitutional rights?

Detailed Legal Analysis

Article 15(1) of the Constitution of India prohibits discrimination on grounds of religion, race, caste, sex, or place of birth, but this provision is primarily enforceable against the state and not directly against private parties. The Supreme Court in several judgments has held that fundamental rights under Part III of the Constitution are enforceable against the state as defined under Article 12, and while some positive obligations have been extended to private actors, discrimination by a purely private employer is generally addressed through statutory law rather than direct constitutional challenge.

However, if the company performs a public function or receives substantial government support, it may fall within the definition of 'state' under Article 12, and then Article 15 and Article 16 (equality of opportunity in employment) become applicable. You can file a complaint with the National or State Human Rights Commission under the Protection of Human Rights Act, 1993, and if the discrimination is caste-based, the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989 may apply.

You can also consider a civil suit for damages if the discrimination violates any applicable labour or employment law.
