Ratione soli or is a Latin phrase meaning "according to the soil" or "by reason of the ownership of the soil."[1] In property law, it is a justification for assigning property rights to landowners over resources found on their own land.[2] 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."[3]
