Ratione soli

Ratione soli or is a Latin phrase meaning "according to the soil" or "by reason of the ownership of the soil." In property law, it is a justification for assigning property rights to landowners over resources found on their own land. Traditionally, the doctrine of ratione soli provides landowners "constructive possession of natural resources on, over, and under the surface: cujus est solum, ejus est usque ad coelum ad infernos."
