Our Constitution provides protection against laws imposing criminal liability for actions committed prior to the enactment of the law. Article 20 (1) under the Part III (Fundamental Rights), reads: 20. (1) No person shall be convicted of any offence except for violation of a law in force at the time of the commission of the act charged as an offence, nor be subjected to a penalty greater than that which might have been inflicted under the law in force at the time of the commission of the offence. Thus, the maximum penalty that can be imposed on an offender cannot exceed those specified by the laws at the time. In the context of the Bhopal Gas tragedy in 1984, the Indian Penal Code (IPC) was the only relevant law specifying criminal liability for such incidents. The CBI, acting on behalf of the victims, filed charges against the accused under section 304 of the IPC (See Note 1). Section 304 deals with punishment for culpable homicide and requires intention of causing death. By a judgment dated September 13, 1996, the Supreme Court held that there was no material to show that “any of the accused had a knowledge that by operating the plant on that fateful night whereat such dangerous and highly volatile substance like MIC was stored they had the knowledge that by this very act itself they were likely to cause death of any human being.” The Supreme Court thus directed that the charges be re-framed under section 304A of the IPC (See Note 2). Section 304A deals with causing death by negligence and prescribes a maximum punishment of two years along with a fine. Consequently, the criminal liability of the accused lay outlined by section 304A of the IPC and they were tried accordingly. Civil liability, on the other hand, was adjudged by the Courts and allocated to the victims by way of monetary compensation. Soon after the Bhopal Gas tragedy, the Government proposed and passed a series of laws regulating the environment, prescribing safeguards and specifying penalties. These laws, among other things, filled the legislative lacunae that existed at the time of the incident. Given the current provisions (See Note 3), a Bhopal like incident will be tried in the National Green Tribunal (once operationalized) and most likely, under the provisions of the the Environment (Protection) Act, 1986. The criminal liability provisions of the Act (See Note 4) prescribe a maximum penalty of five years along with a fine of one lakh rupees. Further, if an offence is committed by a company, every person directly in charge and responsible will be deemed guilty, unless he proves that the offence was committed without his knowledge or that he had exercised all due diligence to prevent the commission of such an offence.

The civil liability will continue to be adjudged by the Courts and in proportion to the extent of damage unless specified separately by an Act of Parliament.

Notes 1) IPC, Section 304. Punishment for culpable homicide not amounting to murder Whoever commits culpable homicide not amounting to murder shall be punished with imprisonment for life, or imprisonment of either description for a term which may extend to ten years, and shall also be liable to fine, if the act by which the death is caused is done with the intention of causing death, or of causing such bodily injury as is likely to cause death, Or with imprisonment of either description for a term which may extend to ten years, or with fine, or with both, if the act is done with the knowledge that it is likely to cause death, but without any intention to cause death, or to cause such bodily injury as is likely to cause death. 2) IPC, Section 304A. Causing death by negligence Whoever causes the death of any person by doing any rash or negligent act not amounting to culpable homicide, shall be punished with imprisonment of either description for a term which may extend to two years, or with fine, or with both. 3) Major laws passed since 1984: 1986 - The Environment (Protection) Act authorized the central government to take measures to protect and improve environmental quality, set standards and inspect industrial units. It also laid down penalties for contravention of its provisions. 1991 - The Public Liability Insurance Act provided for public liability - insurance for the purpose of providing immediate relief to the persons affected by an accident while handling hazardous substances. 1997 - The National Environment Appellate Authority Act established to an appellate authority to hear appeals with respect to restriction of areas in which any industries, operations or processes are disallowed, subject to safeguards under the Environment (Protection) Act, 1986. 2009 - The National Green Tribunal Act, yet to be notified, provides for the establishment of a tribunal for expeditious disposal of cases relating to environmental protection and for giving relief and compensation for damages to persons and property. This Act also repeals the National Environment Appellate Authority Act, 1997. 4) Criminal liability provisions of the Environment Protection Act, 1986 Section 15. Penalty for contravention of the provisions of the Act (1) Whoever fails to comply with or contravenes any of the provisions of this Act, or the rules made or orders or directions issued thereunder, shall, in respect of each such failure or contravention, be punishable with imprisonment for a term which may extend to five years with fine which may extend to one lakh rupees, or with both, and in case the failure or contravention continues, with additional fine which may extend to five thousand rupees for every day during which such failure or contravention continues after the conviction for the first such failure or contravention. (2) If the failure or contravention referred to in sub-section (1) continues beyond a period of one year after the date of conviction, the offender shall be punishable with imprisonment for a term which may extend to seven years. Section 16. Offences by Companies (1) Where any offence under this Act has been committed by a company, every person who, at the time the offence was committed, was directly in charge of, and was responsible to, the company for the conduct of the business of the company, as well as the company, shall be deemed to be guilty of the offence and shall be liable to be proceeded against and punished accordingly: Provided that nothing contained in this sub-section shall render any such person liable to any punishment provided in this Act, if he proves that the offence was committed without his knowledge or that he exercised all due diligence to prevent the commission of such offence.

We wrote an FAQ on the Lok Pal Bill for Rediff.  See http://www.rediff.com/news/slide-show/slide-show-1-all-you-wanted-to-know-about-the-lokpal-bill/20110808.htm The full text is reproduced below. What is the purpose of the Lok Pal Bill? The Bill seeks to establish an institution that will inquire into allegations of corruption against certain public functionaries.  It establishes the office of the Lok Pal for this purpose.   What is the composition of the Lok Pal? The Lok Pal shall consist of a Chairperson and up to eight members.  The Chairperson, and at least half of the members have to be current or former judges of the Supreme Court or Chief Justices of High Courts.  The other members will have at least 25 years experience in matters related to anti-corruption policy, vigilance, public administration, finance, law and management.   Who selects the Lok Pal? The Selection Committee consists of the Prime Minister, Lok Sabha Speaker, the Leader of Opposition in each House of Parliament, a Union Cabinet Minister, a sitting Supreme Court Judge, a sitting High Court Chief Justice, an eminent jurist, a person of eminence in public life.  The two judges on this Committee will be nominated by the Chief Justice of India.   Who comes under the jurisdiction of the Lok Pal? There are seven categories of persons under the Lok Pal: (a) Prime Minister after demitting office; (b) current and former Ministers; (c) current and former MPs (d) all Group A officers of the central government; (e) all Group A equivalent officers or PSUs and other government bodies; (f) directors and officers of NGOs which receive government financing; (g) directors and officers of NGOs which receive funds from the public, and have annual income above a level to be notified by the government. The speech and vote of MPs in Parliament are exempt from the purview of the Lok Pal.   What are the major powers of the Lok Pal? The Lok Pal has two major wings: investigation wing and prosecution wing.  The Lok Pal can ask the investigation wing to conduct preliminary investigation of any offence alleged to be committed under the Prevention of Corruption Act, 1988.  It can then conduct an inquiry.  If the inquiry concludes that an offence was committed, the Lok Pal can recommend disciplinary action.  It can also file a case in the Special Court.   Does the Lok Pal need any prior sanction to initiate any action? No.  The Bill states that the Lok Pal does not need prior sanction to inquire into an offence, or to initiate prosecution in the special court.   What are special courts under this Bill? The central government is required to constitute special courts to hear and decide cases under this Bill.  The Lok Pal shall recommend the number of such courts.   What are the various time limits for conducting inquiry and trial? All preliminary investigation or inquiry must be completed within 30 days of the complaints (and can be extended for a further three months, with written reasons).  The inquiry is to be completed within six months (extendable by six months).  The trial is to be completed within one year of filing the case.  This time may be extended by three months (and in further periods of three months each time) with written reasons, but the total time should not exceed two years.   How can the Lok Pal be removed from office? The President may make a reference to the Supreme Court, (a) either on his own, or (b) if 100 MPs sign a petition, or (c) if a citizen makes a petition and the President is satisfied that it should be referred.  If the Supreme Court, after an inquiry, finds the charge of misbehaviour was valid against the Chairperson or a Member and recommends removal, he shall be removed by the President.   What are the provisions for the expenses of the Lok Pal? The Bill provides that all expenses will be charged, i.e., the amount will be provided without requiring a vote in Parliament.  The Bill estimates recurring expenditure of Rs 100 crore per annum, and a non-recurring expenditure of Rs 50 crore.  It also estimates a further Rs 400 crore for a building.   What are the major differences from the Jan Lok Pal Bill drafted by Team-Anna? There are several differences.  The composition of the Lok Pal and the selection process are different; the Jan Lok Pal draft included a search committee with civil society members to shortlist the eligible members of the Lok Pal.  The Lok Pal had jurisdiction over the PM, the judiciary and all public servants (only Group A officers in the government Bill); it included the speech and vote of MPs in Parliament; it did not include NGOs.  The Jan Lok Pal Bill provided that the investigation and prosecution wings of the CBI shall report to the Lok Pal for corruption cases.  It also had penalties ranging from six months to life imprisonment (under the government Bill, the maximum imprisonment is derived from the Prevention of Corruption Act, 1988, and is 7 years).
