Upon conducting a detailed survey of 27 cases, it was ultimately stated in Paragraph 59 as follows: “59.A journey through the cases set out hereinabove shows that the fundamental underpinning is the principle of proportionality. The aggravating and mitigating circumstances which the Court considers while deciding commutation of penalty from death to life imprisonment, have a large bearing in deciding the number of years of compulsory imprisonment without remission, too. As a judicially trained mind pores and ponders over the aggravating and mitigating circumstances and in cases where they decide to commute the death penalty, they would by then have a reasonable idea as to what would be the appropriate period of sentence to be imposed under the Swamy Shraddananda (supra) principle too. Matters are not cut and dried and nicely weighed here to formulate a uniform principle. That is where the experience of the judicially trained mind comes in as pointed out in V. Sriharan (supra).
