He who is permitted to do the greater may with greater reason do the less.

Explanation

(English-origin maxim.) He who is authorized to do the greater thing is by necessary implication authorized to do the lesser — a grant of broad power includes every narrower power within it.

Where this applies

• A property owner who is allowed to demolish an entire building can certainly remove a single interior wall without needing separate permission.
• A parent who has authority to withdraw a child from school entirely can also excuse the child for a single day.
• A landlord authorized to terminate a lease entirely can also waive a single month's rent, since the lesser power is included in the greater.
