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.

The Arms Act, 1959 governs matters related to acquisition, possession, manufacture, sale, transportation, import and export of arms and ammunition. It defines a specific class of ‘prohibited’ arms and ammunitions, restricts their use and prescribes penalties for contravention of its provisions. Section 7 of the Act forbids the manufacture, sale, and use of prohibited arms and ammunition unless it has been specially authorised by the central government.1  Section 27(3) prescribes that any contravention of Section 7 that results in the death of any person 'shall be punishable with death'.2 Section 27(3) of the Act was challenged in the Supreme Court in 2006 in State of Punjab vs. Dalbir Singh.  The final verdict in the case was pronounced last week.  The judgment not only affects the Act in question but may have important implications for criminal law in the country. Legislative history of Section 27 When the law was first enacted, Section 27 provided that possession of any arms or ammunition with intent to use the same for any unlawful purpose shall be punishable with imprisonment up to seven years and/ or a fine. This section was amended in 1988 to provide for enhanced punishments in the context of escalating terrorist and anti-national activities.  In particular, section 27(3) was inserted to provide for mandatory death penalty. The Judgment The Supreme Court judgment says that Section 27(3) is very 'widely worded'.  Any act (including use, acquisition, possession, manufacture or sale) done in contravention of Section 7 that results in death of a person will attract mandatory death penalty.  Thus, even if an accidental or unintentional use results in death, a mandatory death penalty must be imposed. The bench quotes relevant sections of an earlier judgment delivered in 1983, in Mithu vs. State of Punjab.  In this case, the court had looked into the constitutional validity of mandatory death sentence.  The final verdict had ruled that a provision of law which deprives the Court of its discretion, and disregards the circumstances in which the offence was committed, can only be regarded as 'harsh, unjust and unfair'. The judgment goes on to say that the concept of a 'just, fair and reasonable' law has been read into the guarantees under Article 14 (Equality before law) and Article 21 (Protection of life and personal liberty) of the Constitution.  A law that imposes an irreversible penalty such as death is 'repugnant to the concept of right and reason'.  Therefore, Section 27 (3) of the Arms Act, 1959 is unconstitutional. Section 27(3) is also unconstitutional in that it deprives the judiciary from discharging its duty of judicial review by barring it from using the power of discretion in the sentencing procedure. What happens now? Under Article 13 of the Constitution, laws inconsistent with the Constitution shall be null and void.  Therefore, Section 27(3) of the Arms Act, 1959 shall now stand amended.  Courts shall have the discretion to impose a lesser sentence. It is noteworthy that the Home Minister had also introduced a Bill in the Lok Sabha on the 12th of December, 2011 to amend the Arms Act, 1959.  The Bill seeks to remove the words ‘shall be punishable with death’ and replace these with ‘shall be punishable with death or imprisonment for life and shall also be liable to fine’.  This Bill is currently being scrutinized by the Standing Committee. Notes: 1) Section 7 of the Arms Act, 1959: “7. Prohibition of acquisition or possession, or of manufacture or sale, of prohibited arms or prohibited ammunition.  No person shall -- (a) acquire, have in his possession or carry; or (b) use, manufacture, sell, transfer, convert, repair, test or prove; or (c) expose or offer for sale or transfer or have in his possession for sale, transfer, conversion, repair, test or proof; any prohibited  arms  or  prohibited ammunition unless he has been specially authorised by the Central Government in this behalf.” 2) Section 27(3) of the Arms Act, 1959: “27(3) Whoever uses any prohibited arms or prohibited ammunition or does any act in contravention of section 7 and such use or act results in the death of any other person, shall be punishable with death.” Sources: Arms Act, 1959;  Supreme Court judgment
