Courts have ruled that informing the accused of the grounds of arrest is a mandatory requirement. The Orissa High Court and other courts have emphasized that this is not an empty formality, and non-compliance may vitiate detention and entitle the accused to bail. The Supreme Court has also weighed in, making written grounds of arrest a universal requirement, although the specifics of the ruling, such as the language and format of the notification, are still being clarified by various courts.
