999-year lease

A 999-year lease, under historic common law, is an essentially permanent lease of property. The lease locations are mainly in Britain, its former colonies, and the Commonwealth.
A former colony, the Republic of Mauritius ("The Raphael Fishing Company Ltd v. The State of Mauritius & Anor" (Mauritius) [2008] UKPC 43 (30 July 2008)) established legal precedent on 30 July 2008 in respect of a 'permanent lease' on St. Brandon.
