Something for something.
The legal maxim is of latin origin meaning “what for what” or “something for something”. It is the exchange of things of similar value. a valid and binding mutual consideration agreed upon by two parties in a contractual agreement commonly used as giving of one valuable thing for another. For the formation of a valid contract between two parties, who are not merchants, quid pro quo is an essential element. The presence of a quid pro quo acts as a surety which indicates the sincerity of both the parties in fulfilling the contract.
The literal meaning of the maxim is "Agreements must be kept".
The literal meaning of the maxim is "Agreements must be kept". It is the principle used in the International Law, which means "all the signatories should uphold international treaties". The rule is based upon the principle of "Good Faith". The Good faith indicates that a party cannot invoke the provisions of the domestic law as justification for a failure to perform. The only limit to the maxim is peremptory norms of general international law known as “jus cogens” which denotes the meaning “Compelling law”.
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.

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
