The relevant part of sub section (1) of section 4 and sub section (1) of section 6 of the Act read as under : "4(1) When any person is found guilty of having committed on offence not punishable with death or imprisonment for life and the Court by which the person is found guilty is of opinion that, having regard to the circumstances of the case including the nature of the offence and the character of the offender, it is expedient to release him on probation of good conduct, then, notwithstanding anything contained in any other law for the time being in force, the Court may, instead of sentencing him at once to any punishment, direct that he be released on his entering into a bond, with or without sureties, to appear and receive sentence when called upon during such period, not exceeding three years, as the Court may direct, and in the meantime to keep the peace and be of good behavior." "6(1) When any person under twenty one years of age is found guilty of having committed an, offence punishable with imprisonment (but not with imprisonment for life), the Court by which the person is found guilty shall not sentence him to imprisonment unless it is satisfied that, having regard to the circumstances of the case including the nature of the offence and the character of the offender, it would not be desirable to deal with him under section 3 or section 4, and if the Court passes any sentence of imprisonment on the offender, it shall record its reasons for doing so.
