Matmonim: Daf Yomi by Rabbi David Lapin

Zevachim 26b The Authority to Act - אין מחשבה מועלת אלא במי שראוי לעבודה

Rabbi David Lapin

The effectiveness of an action depends on its physical specifications being correct and on the intent with which it is executed. It also depends on the authority of the person doing it. An action committed by one who lacks the authority to do so, is ineffective.
