This post analyses the ambiguities brought about by defining “life imprisonment” as imprisonment for the remainder of natural life.

The BNS has proposed a change with regards to the definition of ‘imprisonment for life’ under Cl. 4(b), defining it as ‘imprisonment for the remainder of a person’s natural life’. The IPC under s. 53 provides only for the punishment of life imprisonment simpliciter; certain offences of a sexual nature provide for imprisonment for the remainder of a person’s natural life.

I. Current legal interpretation of ‘imprisonment for life’

Courts have interpreted imprisonment for life simpliciter to mean imprisonment for the remaining period of the person’s natural life (‘whole life sentence’).[1] However, ss. 432 and 433, CrPC provide the appropriate government with the power to suspend, remit, or commute a sentence imposed by any court for any offence. The only restriction in such power is provided under s. 433A, CrPC where release of a person sentenced to imprisonment for life is not permitted till they have served at least fourteen years of their actual sentence.

As to whether a whole life sentence can restrict the executive powers of remission, the Supreme Court in Shatrughna Baban Meshram v. State of Maharashtra opined that the statutory prescription of a life sentence that shall mean the remainder of a person’s life can “certainly restrain” such powers.[2] 

Besides, executive power to remit sentences can be taken away by Constitutional courts. The Supreme Court in Union of India v. Sriharan alias Murugan[3] upheld the position in Swamy Shraddhananda (II) v. State of Karnataka[4] that High Courts and the Supreme Court can impose the punishment of a whole life sentence and place it beyond the pale of executive remission based on the circumstances of a particular case. The legal position stipulated in Sriharan, however, does not impinge upon the Constitutional powers of the President and Governor under Arts. 72 and 161 respectively to grant pardon, which cannot be restricted by statutes or judgments of the courts.[5]

II. Potential interpretations of Cl. 4(b)

The intent and implication of the proposed change in definition under Cl. 4(b) of the BNS are not clear. One possible reading is that Cl. 4(b) simply reflects the legal position that life imprisonment in fact means a whole life sentence – with the government’s powers of early release untouched. It is then unclear why some provisions introduced through the BNS state ‘imprisonment for life’ as a possible sentence while some others specifically prescribe ‘imprisonment for life, which shall mean the remainder of that person’s natural life.’ For instance, the offence of organised crime is punishable with imprisonment for life as a possible sentence under Cl. 109(6). However, punishment for murder by life-convicts in Cl. 102 specifically states that the death penalty and imprisonment for life, which shall mean the remainder of that person’s natural life are the two possible sentences. If life sentence means till the end of natural life then using two different articulations across the BNS only creates confusion about the legislative intent.

Notably, Cl. 111 BNS that introduces the offence of ‘terrorist act’ provides life imprisonment without parole as a possible punishment.[6] This is the only provision in the BNS that explicitly restricts parole for a life sentence.

Table 1 provides a list of offences where imprisonment for life is prescribed along with those offences where life sentence till the end of natural life (whole life sentence) is explicitly stated as a possible sentence.

Table 1: Offences punishable by imprisonment for life and whole life sentence

Cl. 4(b) raises another kind of irregularity. Many offences under the BNS lay down imprisonment for life as a possible sentence for an offence while prescribing a whole life sentence for the aggravated form of the same offence. In such a scenario, the penological basis for a higher sentence for the aggravated offence is defeated. For instance, Cl. 64(1) of BNS penalises rape with a sentence ranging from ten years to life imprisonment, while Cl. 64(2) of BNS penalises aggravated form of rape with the same sentence but for the remainder of natural life of the offender. If ‘life imprisonment’ always means a whole life sentence as per Cl. 4(b), the punishments become the same, and the legislative intent for a stricter penalty for aggravated rape is frustrated. Similarly, the punishment for murder under Cl. 101(1) of BNS is imprisonment for life and the death penalty. However, the possible sentence for murder by a life-convict is a whole life sentence along with the death penalty. If imprisonment for life means full life as per Cl. 4(b) then the difference in punishment between murder and murder by life-convicts becomes pointless.

[3] (2016) 7 SCC 1; the dissenting opinion authored by Justice UU Lalit in Sriharan observed that it is not within the powers of courts to impose a special category of fixed term sentence that restricts the exercise of power of remission before the expiry of such stipulated period. Justice Lalit noted that this prohibits the exercise of statutory power designed to achieve rehabilitative purposes.
