Section 84 in Indian Penal Codes

Title: Act of a person of unsound mind

Description: Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law.

Title: Act of a person incapable of judgment by reason of intoxica­tion caused against his will

Description: Nothing is an offence which is done by a person who, at the time of doing it, is, by reason of intoxication, incapable of knowing the nature of the act, or that he is doing what is either wrong, or contrary to law; provided that the thing which intoxicated him was administered to him without his knowledge or against his will.

Title: Offence requiring a particular intent or knowledge committed by one who is intoxicated

Description: In cases where an act done is not an offence unless done with a particular knowledge or intent, a person who does the act in a state of intoxication shall be liable to be dealt with as if he had the same knowledge as he would have had if he had not been intoxicated, unless the thing which intoxicated him was administered to him without his knowl­edge or against his will.

Title: Act not intended and not known to be likely to cause death or grievous hurt done by consent

Description: Nothing which is not intended to cause death, or grievous hurt, and which is not known by the doer to be likely to cause death or grievous hurt, is an offence by reason of any harm which it may cause, or be intended by the doer to cause, to any person, above eighteen years of age, who has given consent, whether express or implied, to suffer that harm; or by reason of any harm which it may be known by the doer to be likely to cause to any such person who has consented to take the risk of that harm. Illustration A and Z agrees to fence with each other for amusement. This agreement implies the consent of each to suffer any harm which, in the course of such fencing, may be caused without foul play; and if A, while playing fairly, hurts Z, A commits no offence.

Title: Act not intended to cause death done by consent in good faith for person’s benefit

Description: Nothing which is not intended to cause death, is an offence by reason of any harm which it may cause, or be intended by the doer to cause, or be known by the doer to be likely to cause, to any person for whose benefit it is done in good faith, and who has given a consent, whether express or implied, to suffer that harm, or to take the risk of that harm. Illustration A, a surgeon, knowing that a particular operation is likely to cause the death of Z, who suffers under a painful complaint, but not intending to cause Z’s death and intending in good faith, Z’s benefit performs that operation on Z, with Z’s consent. A has committed no offence.
