The Court observed that âThe courts are normally rigorous in requiring the power to
be exercised by the persons or the bodies authorised by the statutes. It is essential that the
delegated power should be exercised by the authority upon whom it is conferred and by no
one elseâŚ..Due to the enormous rise in the nature of the activities to be handled by
statutory authorities, the maxim delegates non-potest delegate is not being applied
especially when there is a question of exercise of discretionary administrative power.â
There are the following expectations:-
The maxim does not apply or lose its importance in the administrative field-
1. Where the principal/enabling Act himself authorises the delegation.
2. Where the delegation is necessary.
3. where the custom and practice require or allow delegation.
Conclusion-
The legal maxim âDelegates Non-Potest Delegareâ does not lay down the rule of law.
It merely states a rule of construction of a statute.
Generally, sub-delegation of legislative power is impermissible, yet it can be
permitted either when such power is expressly conferred under the statute or can be
inferred by necessary implication. This is so because there is a well-established principle
that a sub-delegate cannot act beyond the scope of power delegated to him.
(B) Expressio unius est exclusion alterius:-
Expressio unius est exclusio alterius means express mention of one thing excludes all
others. This is one of the rules used in the interpretation of statutes. The phrase indicates
that items not mentioned in the list are presumed not to be covered by the statute. When
something is mentioned expressly in a statute it leads to the presumption that the things
not mentioned are excluded. However, sometimes a list in a statute is illustrative and not
exclusionary. This is usually indicated by a word such as "includes" or "such as."
General words in a statute must receive a general construction . Whenever something
is added in the statute, it is added with due consciousness. It is assumed that if something
is not added to the statute, there is a reason behind it, which is to exclude that from the
particular statute.
For example, if a Statute refers to Lions and Tigers, it only refers to them and will
not include Leopards, hyenas or any other wild animals.
