Contra Bonos Mores

A delegate cannot further delegate.

This Latin maxim means that a person to whom a power is delegated cannot further delegate that power. That person cannot sub-delegate that power to someone else. No sub-delegation can be done in a contract of principle-agent without the knowledge and consent of the principle. This principle is often used in administrative or constitutional law.

The scene of the event

Locus in quo is a Latin maxim, which means “the scene of the event” or “the place in which”. In general sense it means the place where the cause of action arose, i.e. the place where something is alleged to have occurred.

A Defendant's Mental State

This maxim refers to the state of mind of the defendant who is proved to be having ulterior motives when having committed a crime. Mens réa is defined in a statute which establishes the crime or sets a precedent from time to time. The teaching of Mens rea was applied in India by courts, now that mens rea is the most important component of an offence, as firmly settled by law. In addition, the offenses resulting from the Prevention of Food Adulteration Act, Drug Acts and Weights and Measurements Act are prohibited without any evidence of guilt and the criminal shall not be liable for the offense without the proof of any guilty knowledge or intention, as it also decided by the Hon’ble Supreme Court in the case of Sarjoo Prasad v/s State of U.P
