Section 93 in Indian Penal Codes
Title: Communication made in good faith
No communication made in good faith is an offence by reason of any harm to the person to whom it is made, if it is made for the benefit of that person. Illustration A, a surgeon, in good faith, communicates to a patient his opinion that he cannot live. The patient dies in consequence of the shock. A has committed no offence, though he knew it to be likely that the communication might cause the patient’s death.
Title: Act to which a person is compelled by threats
Except murder, and offences against the State punishable with death, nothing is an offence which is done by a person who is compelled to do it by threats, which, at the time of doing it, reasonably cause the apprehension that instant death to that person will otherwise be the consequence: Provided the person doing the act did not of his own accord, or from a reasonable apprehension of harm to himself short of instant death, place himself in the situation by which he became subject to such constraint. Explanation 1.—A person who, of his own accord, or by reason of a threat of being beaten, joins a gang of dacoits, knowing their character, is not entitled to the benefit of this exception, on the ground of his having been compelled by his associates to do anything that is an offence by law. Explanation 2.—A person seized by a gang of dacoits, and forced, by threat of instant death, to do a thing which is an offence by law; for example, a smith compelled to take his tools and to force the door of a house for the dacoits to enter and plunder it, is entitled to the benefit of this exception.
Title: Act causing slight harm
Nothing is an offence by reason that it causes, or that it is intended to cause, or that it is known to be likely to cause, any harm, if that harm is so slight that no person of ordinary sense and temper would complain of such harm.
Title: Things done in private defence
Nothing is an offence which is done in the exercise of the right of private defence.
Title: Right of private defence of the body and of property
Every person has a right, subject to the restrictions contained in section 99, to defend—
(First) — His own body, and the body of any other person, against any offence affecting the human body;
(Secondly) —The property, whether movable or immovable, of himself or of any other person, against any act which is an offence falling under the definition of theft, robbery, mischief or criminal trespass, or which is an attempt to commit theft, robbery, mischief or criminal trespass.
