illustrations :
 
1) A is sentenced to a fine of one hundred rupees and to four months’ imprisonment in default of payment. Here, if seventy-five rupees of the fine be paid or levied before the expiration of one month of the imprisonment, A will be discharged as soon as the first month has expired. If seventy-five rupees be paid or levied at the time of the expiration of the first month, or at any later time while A continues in imprisonment, A will be immediately discharged. If fifty rupees of the fine be paid or levied before the expiration of two months of the imprisonment, A will be discharged as soon as the two months are completed. If fifty rupees be paid or levied at the time of the expiration of those two months, or at any later time while A continues in imprisonment, A will be immediately discharged.
IPC Section 70 : Fine leviable within six years, or during imprisonment – Death not to discharge property from liability
The fine, or any part thereof which remains unpaid, may be levied at any time within six years after me passing of the sentence, and if, under the sentence, the offender be liable to imprisonment for a longer period than six years, then at any time previous to the expiration of that period; and the death of the offender does not discharge from the liability any property which would, after his death, be legally liable for his debts.
IPC Section 71 : Limit of punishment of offence made up of several offences
Where anything which is an offence is made up of parts, any of which parts is itself an offence, the offender shall not be punished with the punishment of more than one of such his offences, unless it be so expressly provided.
 
Where anything is an offence falling within two or more separate definitions of any law in force for the time being by which offences are defined or punished, or
 
where several acts, of which one or more than one would by itself or themselves constitute an offence, constitute, when combined, a different offence,
 
the offender shall not be punished with a more severe punishment than the Court which tries him could award for any one of such offences.


illustrations :
 
1) A gives Z fifty strokes with a stick. Here A may have committed the offence of voluntarily causing hurt to Z by the whole beating, and also by each of the blows which make up the whole beating. If A were liable to punishment for every blow, he might be imprisoned for fifty years, one for each blow. But he is liable only to one punishment for the whole beating.
 
2) But if, while A is beating Z, Y interferes, and A intentionally strikes Y, here, as the blow given to Y is no part of the act whereby A voluntarily causes hurt to Z, A is liable to one punishment for voluntarily causing hurt to Z, and to another for the blow given to Y.
IPC Section 72 : Punishment of person guilty of one of several offences, the judgment stating that it is doubtful of which
In all cases in which judgment is given that a person is guilty of one of several offences specified in the judgment, but that it is doubtful of which of these offences, he is guilty, the offender shall be punished for the offence for which the lowest punishment is provided if the same punishment is not provided for all.
IPC Section 73 : Solitary confinement
Whenever any person is convicted of an offence for which under this Code the Court has power to sentence him to rigorous imprisonment, the Court may, by its sentence, order that the offender shall be kept in solitary confinement for any portion or portions of the imprisonment to which he is sentenced, not exceeding three months in the whole, according to the following scale, that is to say -
 
1) a time not exceeding one month if the term of imprisonment shall not exceed six months;

2) a time not exceeding two months if the term of imprisonment shall exceed six months and shall not exceed one year;

3) a time not exceeding three months if the term of imprisonment shall exceed one year.
IPC Section 74 : Limit of solitary confinement
In executing a sentence of solitary confinement, such confinement shall in no case exceed fourteen days at a time, with intervals between the periods of solitary confinement of not less duration than such periods; and when the imprisonment awarded shall exceed three months, the solitary confinement shall not exceed seven days in any one month of the whole imprisonment awarded, with intervals between the periods of solitary confinement of not less duration than such periods.
IPC Section 75 : Enhanced punishment for certain offences under Chapter XII or Chapter XVII after previous conviction
Whoever, having been convicted,—
 
by a court in India, of an offence punishable under Chapter XII or Chapter XVII of this Code with imprisonment of either description for a term of three years or upwards, shall be guilty of any offence punishable under either of those Chapters with like imprisonment for the like term, shall be subject for every such subsequent offence to imprisonment for life, or to imprisonment of either description for a term which may extend to ten years.
