SURJEET SINGH & ANR. vs UNION OF INDIA & ORS.

The Supreme Court held that under Article 22(5) of the Constitution, a detained person must be informed of the grounds for their detention in a language they understand. The Court found that the detention of Surjeet Singh and Kulwant Singh was unlawful as the grounds were communicated in English, which they did not comprehend, thus violating their constitutional rights. The Court quashed the detention orders, emphasizing the necessity of providing grounds in the detainee's mother tongue for effective communication.
