Permanent grant
A 999-year lease, under historic common law, is a permanent lease of property.
Permanent lease locations are in Britain, its former colonies and the Commonwealth.
A former colony, the Republic of Mauritius established a legal precedent through a decision of the Judicial Committee of the Privy Council (The Raphael Fishing Company Ltd v. The State of Mauritius & Anor (Mauritius) [2008] UKPC 43 (30 July 2008)) on 30 July 2008 in respect of a 1901 'permanent lease' on the following islands of St. Brandon (Cargados Carajos) :
