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 Monetary Policy Committee (MPC) has decided to conduct an off-cycle meeting today to discuss the failure to meet the inflation target under Section 45ZN of the Reserve Bank of India Act, 1934. As per the Reserve Bank of India Act (RBI), 1934, MPC is required to meet at least four times each year, to discuss the macroeconomic issues in the country, and take policy decisions to address those. This is the second time MPC has conducted an off-cycle meeting in 2022-23. The meeting is scheduled in light of inflation being consistently high for nine consecutive months.

In this blog, we discuss what the inflation targeting framework is, examine retail and wholesale prices, and the divergence between them.   

What is the inflation targeting framework, and what happens if inflation is persistently high?

In 2016, Parliament amended the RBI Act, 1934 to change the monetary policy, and introduce an inflation targeting framework. This framework prioritises price stability to achieve sustainable GDP growth. Price stability allows investors to confidently invest their money for productive activities, without worrying about it losing value. Price stability also maintains the purchasing power of consumers, i.e., the ability to purchase a good (or service) with a given amount of money.

As per the new framework, the central government, in consultation with RBI sets: (i) an inflation target, and (ii) an upper and lower tolerance level for retail inflation. The target has been set at 4%, with an upper tolerance limit of 6% and a lower tolerance limit of 2%. The upper and lower limits indicate that although it is desirable for inflation to be close to 4%, deviation between these limits is acceptable. The target and bands are revised every five years. In March 2021, the existing targets were carried forward.  

Retail inflation has been above 6% for the past nine months, and it has been above 4% from October 2019 onwards (See Figure 1).

If inflation is above or below the prescribed limits for three quarters, RBI must submit a report to the central government explaining why prices have been rising (or falling) persistently, what will be done to correct that, and an estimate as to when the target will be achieved.   

The MPC uses tools such as interest rates to control the level of inflation in the economy. One such rate is the policy repo rate, which is the rate at which RBI lends money to banks. An increase in the policy repo rate makes borrowing money more costly, and hence is expected to control inflation by reducing the money supply. MPC increased this rate from 4% in April 2022 to 4.4% in May 2022, to 4.9% in June 2022, to 5.4% in August 2022, and to 5.9% in September 2022.

Breaking down the Consumer Price Index and the Wholesale Price Index

Consumer Price Index (CPI) measures the general prices of goods and services such as food, clothing, and fuel over time. Retail inflation is calculated as the change in the CPI over a period of time. Goods and services such as petrol, food products, health, and education are considered for its calculation, which are assigned different weights (See Table 1). Between February 2022 and August 2022, the average annual inflation was 6.9%. The rise in prices of subcomponents of the CPI during this period is indicated in Table 2.

CPI is not the only index that measures inflation in an economy. The Wholesale Price Index (WPI) measures the wholesale prices of goods. A change in wholesale prices reflects wholesale inflation. Table 3 indicates the weights assigned to goods for calculating the WPI. Manufactured goods include metals, chemicals, food products, and textiles.   

Primary articles (23%) include food articles, and crude petroleum and natural gas. Fuel and power (12%) include mineral oils, electricity, and coal.  WPI has remained above 10% from April 2021 onwards. It reached an all-time high of 17% in May 2022. This was driven by the inflation in metals, kerosene and petroleum coke, fruits and vegetables, and palm oil.

Why has WPI inflation been consistently above CPI inflation?

Movements in the WPI have an impact on the CPI.  For almost a year and half, CPI inflation has remained below WPI inflation.  However, as per the design of the indices, it is expected that CPI would remain above WPI, and that any increase in WPI would reflect in the CPI after a time lag.  This is because retail prices include taxes (as a percentage of price), while wholesale prices do not.  Additionally, some of the goods in WPI act as inputs in the goods considered in CPI.  An increase in input prices would lead to higher retail prices after a time lag.

We discuss possible reasons for why CPI has remained below WPI for a year and a half.

Composition of indices

As indicated in Table 2 and 3, the composition of the two indices varies. For instance, prices of manufacture of basic metals, chemicals, and machinery grew at an average rate of 13% between February 2021 and September 2022.  They contribute 7% to the WPI. These are input goods for producing final goods and services such as automobiles, which are included in the CPI. The rise in prices of transport vehicles, communication devices, fuel for transport, and housing (CPI components) rose by 6% during this period.

The Ministry of Finance has observed that wholesale prices did not feed into retail prices (from March 2021 onwards) as wholesalers absorbed the rising input costs and did not pass them on to retailers. In August 2022, it noted that as retail prices are rising now, the pass-through may occur.
