AD COELUM ET AD INFEROS
common law concept that means from the heavens to the centre,
the owner of land owns from the centre of the earth to the heavens.
However, such a concept is not accepted as necessary in the defionition of land.
The concept has been significanly modified by
necessity and statute. Otherwise the owner of land can sue an aircraft
for trespass and claim all minerals
below their land. At common law, royal minerals have always been exempted.
