A more thorough explanation:

MEDIO

Medio is a legal term that refers to a writ used in medieval times to protect an undertenant from harassment by a paramount lord for rent actually due from the mesne lord. It is also known as a writ of mesne.

An example of medio would be if a tenant rented land from a mesne lord, who in turn rented the land from a paramount lord. If the mesne lord failed to pay the rent owed to the paramount lord, the paramount lord could try to collect the rent from the tenant. The tenant could then use a writ of medio to protect themselves from being harassed by the paramount lord.

Another example would be if a tenant was being evicted by a mesne lord, but the eviction was not lawful. The tenant could use a writ of medio to protect themselves from being evicted without proper legal procedures being followed.

Medio was a legal tool used in medieval times to protect tenants from being harassed or mistreated by their landlords. It was used to ensure that the proper legal procedures were followed and that tenants were not unfairly punished for the actions of their landlords. The examples illustrate how medio was used to protect tenants from harassment and eviction by their landlords.
