2. What counts as land

Airspace, mines, and the Sierra Leone definition

Posted By lanbuk.com

In simple terms

Land is more than the surface. It takes in what is fixed to it, mines and minerals, and some of the air above. It does not, in the modern cases, reach to the heavens.

The old maxim is : who owns the soil owns up to the heavens and down to the depths. Bowen LJ in Pountney v Clayton gives the cautious version. , the owner has everything under the sky down to the centre of the earth.

The courts have cut the maxim down. Griffiths J in Bernstein v Skyviews called it a colourful phrase. In United States v Causby the United States Supreme Court said it had no place in the modern world. The Privy Council said the same in Commissioner for Railways v Valuer-General. The useful right is to the airspace the owner needs for the ordinary use of the land, not to an infinite column.

Section 205 of the Law of Property Act 1925, which does not itself apply in Sierra Leone, defines land widely: land of any tenure, mines and minerals, , and easements, rights and privileges over land. Section 4 of the Interpretation Act 1971 is to the same effect. In Sierra Leone, land includes land covered by water, any house, building or structure, and any estate, interest or right in or over land or water.

What the may do with that land is another question. , and the stop a use that injures a neighbour. Gold and silver were the Crown's at common law. In Sierra Leone minerals are dealt with by statute. The statutes are the Minerals Act and The Mines and Minerals Act, 2009. Other statutes take slices of the owner's freedom: forestry, the Guma Valley, civil aviation, defence, The Public Lands Ordinance, 1898, town planning, and public health.

Wild animals are no one's until they are killed or taken. In Sutton v Moody an animal killed by a belonged to the landowner. In a non-tidal river the owner of the bed has the fishing. In a tidal river the public may fish, and the bed is the State's. A riparian owner may take water for ordinary purposes. Embrey v Owen and Rugby Joint Water Board v Walters are the authorities for reasonable use, without a substantial change in quality or volume.

Things found on the land are not automatically the finder's. Parker v British Airways Board and City of London Corporation v Appleyard sort out the occupier's rights and the finder's.

Words and Latin in this note

Rule in Rylands v Fletcher
Strict liability of a landowner who brings onto his land something likely to do harm if it escapes, and it does escape and cause damage. Open the note.
Cuius est solum
'Who owns the soil owns up to the heavens and down to the depths.' A colourful phrase. It does not give the owner a claim for every overflight. The right stops at the airspace needed for ordinary use of the land.
Hereditament
A right that can be inherited. A corporeal hereditament is the physical land. An incorporeal one is a right over land you cannot pick up, such as an easement. Open the note.
Prima facie
At first sight: evidence strong enough to prove a point unless it is answered or contradicted. Open the note.
Fee simple
The fullest form of land ownership: the owner holds the land for ever and can sell, give away or leave it by will. Open the note.
Nuisance
Unreasonable interference with a person's use or enjoyment of land (private nuisance) or with the rights of the public (public nuisance). Open the note.
Fixture
A chattel that has become part of the land, because of how firmly it is fixed and why. It passes with the land unless the contract says otherwise. Open the note.
