Senior Congress leader P Chidambaram on Thursday criticised the three key bills brought by the government that seek to overhaul the criminal justice system, saying the opportunity to replace and redraft the colonial laws has been "wasted".

The Lok Sabha on Wednesday passed three key bills -- the Bharatiya Nyaya (Second) Sanhita, Bharatiya Nagarik Suraksha (Second) Sanhita and the Bharatiya Sakshya (Second) Bill -- that seek to overhaul the criminal justice system.
