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 doctrine of separation of powers implies that each pillar of democracy – the executive, legislature and the judiciary – perform separate functions and act as separate entities.  The executive is vested with the power to make policy decisions and implement laws.  The legislature is empowered to issue enactments.  The judiciary is responsible for adjudicating disputes.  The doctrine is a part of the basic structure of the Indian Constitution[1] even though it is not specifically mentioned in its text.  Thus, no law may be passed and no amendment may be made to the Constitution deviating from the doctrine.  Different agencies impose checks and balances upon each other but may not transgress upon each other’s functions.  Thus, the judiciary exercises judicial review over executive and legislative action, and the legislature reviews the functioning of the executive. There have been some cases where the courts have issued laws and policy related orders through their judgements.  These include the Vishakha case where guidelines on sexual harassment were issued by the Supreme Court, the order of the Court directing the Centre to distribute food grains (2010) and the appointment of the Special Investigation Team to replace the High Level Committee established by the Centre for investigating black money deposits in Swiss Banks. In 1983 when Justice Bhagwati introduced public interest litigation in India, Justice Pathak in the same judgement warned against the “temptation of crossing into territory which properly pertains to the Legislature or to the Executive Government”[2].  Justice Katju in 2007 noted that, “Courts cannot create rights where none exist nor can they go on making orders which are incapable of enforcement or violative of other laws or settled legal principles. With a view to see that judicial activism does not become judicial adventurism the courts must act with caution and proper restraint. It needs to be remembered that courts cannot run the government. The judiciary should act only as an alarm bell; it should ensure that the executive has become alive to perform its duties.” [3] While there has been some discussion on the issue of activism by the judiciary, it must be noted that there are also instances of the legislature using its law making powers to reverse the outcome of some  judgements.  (M.J. Antony has referred to a few in his article in the Business Standard here.)  We discuss below some recent instances of the legislature overturning judicial pronouncements by passing laws with retrospective effect. On September 7, 2011 the Parliament passed the Customs Amendment and Validation Bill, 2011 which retrospectively validates all duties imposed and actions taken by certain customs officials who were not authorized under the Customs Act to do the stated acts.  Some of the duties imposed were in fact challenged before the Supreme Court in Commissioner of Customs vs. Sayed Ali in 2011[4].  The Supreme Court struck down the levy of duties since these were imposed by unauthorised officials.  By passing the Customs Bill, 2011 the Parliament circumvented the judgement and amended the Act to authorize certain officials to levy duties retrospectively, even those that had been held to be illegal by the SC. Another instance of the legislature overriding the decision of the Supreme Court was seen in the Essential Commodities (Amendment) Ordinance, 2009 which was passed into an Act.  The Supreme Court had ruled that the price at which the Centre shall buy sugar from the mill shall include the statutory minimum price (SMP) and an additional amount of profits that the mills share with farmers.[5] The Amendment allowed the Centre to pay a fair and remunerative price (FRP) instead of the SMP.  It also did away with the requirement to pay the additional amount.  The amendment applied to all transactions for purchase of sugar by the Centre since 1974.  In effect, the amendment overruled the Court decision. The executive tried to sidestep the Apex Court decision through the Enemy Property (Amendment and Validation) Ordinance, 2010.  The Court had issued a writ to the Custodian of Enemy Property to return possession of certain properties to the legal heir of the owner.   Subsequently the Executive issued an Ordinance under which all properties that were divested from the Custodian in favour of legal heirs by a Court order were reverted to him.  The Ordinance lapsed and a Bill was introduced in the Parliament.  The Bill is currently being examined by the Parliamentary Standing Committee on Home Affairs. These examples highlight some instances where the legislature has acted to reverse judicial pronouncements.  The judiciary has also acted in several instances in the grey areas separating its role from that of the executive and the legislature.  The doctrine of separation of powers is not codified in the Indian constitution.  Indeed, it may be difficult to draw a strict line demarcating the separation.  However, it may be necessary for each pillar of the State to evolve a healthy convention that respects the domain of the others.
