(1.) S. 428 of the Criminal Procedure Code, 1973, under which these petitions have been filed and which is of critical importance here provides: "where an accused person has, on conviction, been sentenced to imprisonment for a term, the period of detention, if any, undergone by him during the investigation, inquiry or trial of the same case and before the date of such conviction, shall be set-off against the term of imprisonment imposed on him on such conviction, and the liability of such person to undergo imprisonment on such conviction shall be restricted to the remainder, if any of the term of imprisonment imposed on him. "' This is a new provision. It allows set-off of periods of detention against terms of imprisonment covered by sentences. The sentences should be in force on the date of set-off. The mere fact of pendency of an appeal or proceeding in revision from the conviction and sentence would not by itself stop operation of the sentence. Unless the sentence is suspended or the accused is let out on bail by the appellate or revisional court the conviction and sentence appealed from or sought to be revised would continue to operate. Therefore set-off can be made under the section so long as there is no order of the appellate or revisional court suspending the sentence or releasing the accused on bail.
(2.) THERE is scope for set-off only when there is a legally enforceable sentence. Set-off proceeds on the assumption that the entire sentence passed is valid and enforceable. In fact the sentence awarded by judgment after conviction forms the foundation for set-off. No doubt after set-off the liability of the convict to suffer imprisonment is reduced to the balance period. But that balance period and the period of detention when added make up the full term of imprisonment awarded by the judgment of court. Indirectly the granting of set-off allows the term of imprisonment awarded to be calculated from the date of commencement of detention. Thus by granting set-off only credit is given to the convict in the calculation of the term of imprisonment awarded to him for the period he was in detention. It does not in any manner alter the sentence or the judgment entering conviction and awarding sentence. They remain the same even after set-off.
(3.) THE set-off contemplated by S. 428 of the Crl. P. C. is against "term of imprisonment". Although in common parlance "imprisonment for life" is considered as "imprisonment" they are treated as two different kinds of punishment in the IPC. and the Crl. P. C. ; "imprisonment for life" is not "imprisonment" there. A monkey is not necessarily a man because he is descended from the same anthropoid ancestors. As stated by Ogden and Richards in their work on the'meaning of Meaning', words have no real existence in themselves, they are, in fact, only a special class of symbols, the most important class of signs used in thinking and communication and therefore words and verbal analysis receive meaning only by reference to an object or a situation in the real world, called 'referent' by Ogden and Richards. What is the 'referent' here? In s. 53 of the IPC. "imprisonment for life" is considered a category by itself distinct from the category of "imprisonment". In S. 389. of the crl. P. C. which deals with suspension of sentence pending appeal "imprisonment for life" and "imprisonment for a term" are treated in clause (4) as two distinct punishments. THErefore the two expressions, "imprisonment for life" and "term of imprisonment" have to be treated as distinct and separate, the latter not being a genus of which the former is a specie and they being mutually exclusive. S. 428 of the Crl. P. C, lakes into account for set-off only "term of imprisonment" and not "imprisonment for life". In that view also convicts sentenced to imprisonment for life are hot entitled to get the benefits of S. 428 of the Crl. P. C.
