Delegata potestas non potest delegari
（重定向自Delegatus non potest delegare）
In constitutional and administrative law, the principle delegata potestas non potest delegari (Latin) states that "no delegated powers can be further delegated". Alternatively, it can be stated delegatus non potest delegare, "one to whom power is delegated cannot himself further delegate that power". This principle is present in several jurisdictions such as that of the United States, the United Kingdom and India, and in Catholic canon law.
