To permit is to allow by passive consent or not hindering; or to grant leave to by express consent or authorization.

Explanation

(English-origin maxim.) Permission may be given either expressly by words of authorization or impliedly by passive acquiescence — silence in the face of another's act may constitute permission.

Where this applies

• A homeowner watches her neighbor build a shed that extends two inches onto her property and says nothing for years — her silence is treated as passive permission.
• A parent signs a consent form expressly authorizing a school field trip, giving permission by direct authorization.
• A landlord sees a tenant install a satellite dish on the roof and does not object, and the court treats the landlord's silence as implied permission.
