The full import of this maxim is whenever anything is authorised, and especially if, as a matter duty required to be done by law, it is found impossible to do that thing unless something else not authorised in express terms be also done, may also be done, then that something else will be supplied by necessary intendment. Ex debitio justitiae is inbuilt in such exercise; the whole idea is to do real, complete and substantial justice for which it exists. [Gian Singh v. State of Punjab, (2012) 10 SCC 303]. [Section 482, Criminal Procedure Code, 1973]
When the law gives anything to anyone, it also gives all those things without which the thing itself would be unavoidable. [Amit Kapoor v. Ramesh Chander, (2012) 9 SCC 460]. [Section 482, Criminal Procedure Code, 1973].
