The Supreme Court's latest landmark verdict against police's century-old discretionary powers concerning arrest, detention and remand is a bold judicial pronouncement in favour of people's liberty and fundamental rights.

Police personnel from different tiers have welcomed the Supreme Court's landmark verdict on police's powers concerning arrest, detention in custody and remand, but said the provision for making arrests on suspicion is necessary for tackling crimes.

The Supreme Court will deliver a verdict today on a long-pending appeal against the High Court directives on the detention of any person under suspicion and subsequent dealings with the detainees on remand.
