ACT IN PAIS

“A delegated authority cannot again be delegated.”

A person to whom some power is delegated cannot sub-delegate that power to someone else.

“The person who consents cannot complain.”

It is a Latin maxim, which means that the person who voluntarily gives consent for any harm to suffer would not be liable to claim any damages for the same. This consent could be used as a good defence against the plaintiff. Hence, the person who himself waived or abandoned his right voluntarily, cannot have any claim over it.

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”.
