The Commissioners in Lunacy, alternatively the Lunacy Commission, was a public body which was established by the Lunacy Act 1845 to oversee asylums and the welfare of mentally ill people in England and Wales. Its origin comprises the County Asylums Act 1808, which was alternatively called the 'Lunatic Paupers' or the 'Criminals Act 1808' or, after its promoter Charles Williams-Wynn (1775–1850), 'Wynn's Act'. This Act was replaced by the County Lunatic Asylums (England) Act 1828, informally the Madhouse Act 1828, which introduced the 'Metropolitan Commissioners in Lunacy'. By 1842 the scope of the 'Metropolitan Commissioners in Lunacy' had been enlarged from London to cover the whole country. And the jurisdiction of the Lord Chancellor over lunatics, so found by writ of De Lunatico Inquirendo, had been delegated to two Masters-in-Chancery. The 'Lunacy Act 1842' established the 'Commissioners in Lunacy', and was repealed by the Lunacy Act 1845, by which the Commissioners were retitled 'Masters in Lunacy'.
