Blackstone’s Dictum presents the Latin legal expression—Cuius est solum eius est usque ad coelum et ad inferos—of William Blackstone, the influential 18th century English jurist. Originally contained within his treatise Commentaries on the Laws of England, it eloquently expresses the right of a landowner to control the earth below his/her property and the air above it.
The text of Blackstone’s Dictum leaves out ‘et’—Latin for ‘and’—because the structure of the trifold performs the conjunction.
