“14. Thus, the requirement of informing the person arrested of the grounds of arrest is not a formality but a mandatory constitutional requirement. Article 22 is included in Part III of the Constitution under the heading of Fundamental Rights. Thus, it is the fundamental right of every person arrested and detained in custody to be informed of the grounds of arrest as soon as possible. If the grounds of arrest are not informed as soon as may be after the arrest, it would amount to a violation of the fundamental right of the arrestee guaranteed under Article 22(1). It will also amount to depriving the arrestee of his liberty. The reason is that, as provided in Article 21, no person can be deprived of his liberty except in accordance with the procedure established by law. The procedure established by law also includes what is provided in Article 22(1). Therefore, when a person is arrested without a warrant, and the grounds of arrest are not informed to him, as soon as may be, after the arrest, it will amount to a violation of his fundamental right guaranteed under Article 21 as well. In a given case, if the mandate of Article 22 is not followed while arresting a person or after arresting a person, it will also violate fundamental right to liberty guaranteed under Article 21, and the arrest will be rendered illegal. On the failure to comply with the requirement of informing grounds of arrest as soon as may be after the arrest, the arrest is vitiated. Once the arrest is held to be vitiated, the person arrested cannot remain in custody even for a second.”
