New Delhi: The much-awaited Anti-rape Bill was introduced in the Rajya Sabha on Wednesday. Earlier on Tuesday, the Lok Sabha passed the Anti-rape Bill or the Criminal Law (Amendment) Bill after heated exchange of words by the members of Parliament.

The Bill was passed only after all amendments moved by Opposition and one by UPA constituent NCP for a life-term for perpetrators of acid attacks were defeated.

The passed Anti-rape Bill keeps the age for consensual sex at 18 years and makes voyeurism and stalking punishable offences.

The Criminal Law (Amendment) Bill, 2013, was tabled in the House by Union Home Minister Sushilkumar Shinde a day after the Cabinet approved its draft. The Anti-rape Bill will replace the ordinance promulgated by President Pranab Mukherjee on February 3.

During the debate, members across the political divide expressed their concerns on some of the provisions. Congress member Sandeep Dikshit wondered that if a girl and a boy aged between 16 and 18 get into physical relations, "would they be called criminals" while Bharatiya Janata Party's Sumitra Mahajan defended the decision to keep the age of consent at 18. She, however, noted steps should be taken to prevent misuse of some provisions.

The Bill seeks to punish repeat offenders of rape with imprisonment of life (which shall mean the remainder of the person's natural life), or with death. It says that those convicted for the offence of gang-rape shall be punished with rigorous imprisonment for a minimum of 20 years extendable to life imprisonment.

It also defines and prescribes punishment for stalking, voyeurism and sexual harassment.The Bill says that all hospitals shall immediately provide first aid and/or medical treatment free of cost to the victims of acid attack or rape.

The Anti-rape Bill will replace the ordinance promulgated by President Pranab Mukherjee on February 3. The legislation had to be passed by Parliament before April 4, when it would have lapsed. The issue has been in focus after the gang-rape of a 23-year-old woman in Delhi Dec 16 last year. She died of grievous injuries 13 days later.
