The codification of Manx customary law at Tynwald. The breast law — the legal tradition carried in the memory of the Deemsters — was written down for the first time. This was not the imposition of new law but the recording of what the Deemsters already knew and applied. The codification preserved the Island's legal tradition in a form that would survive the centuries.
The Act of Settlement codified the relationship between the Lord of Mann and the Manx people, securing land rights and defining the terms of custodianship. It happened because the Lord needed his tenants to invest in land they believed was theirs — the alignment of interest producing constitutional settlement. This was the arrangement Parliament purchased in 1765 without understanding what it was buying. Text available in Lex Scripta (1819), pp. 190–209.
5 Geo. III, c. 26 — 'An Act for more effectually preventing the mischiefs arising to the Revenue and Commerce of Great Britain and Ireland, from the illicit and clandestine Trade to and from the Isle of Mann.' Parliament purchased the Duke of Atholl's sovereignty and revenue rights for £70,000. The Act purchased a feudal title. It did not acquire the Manx nation. It did not assume the duty of governance that came with the title. The justification was revenue protection — the East India Company's commercial interests dressed as fiscal necessity.
Companion legislation to the Purchase Act, extending British customs law to the Isle of Man and criminalising the trade that had been legal under Manx law. What had been commerce became contraband overnight. The Act imposed the full weight of the British customs establishment on an island whose entire commercial infrastructure was built on the trade Parliament had just abolished.
Further legislation tightening enforcement against the trade between the Isle of Man and Britain. The legislative package of 1765 — the Purchase Act, the Mischief Act, the Smuggling Act — together dismantled the Island's commercial system.
6 Geo. IV, c. 34 — the second purchase. Parliament bought the remaining Atholl rights that had been reserved in the 1765 Act. Surveys and arbitrations were conducted 1826–28 to value the properties. The final purchase completed what the 1765 Act had begun — the total transfer of the lordship to the Crown.
Gave Manx people the right to elect their own representatives to the House of Keys for the first time. Previously the Keys had been a self-electing body. The Act was the culmination of forty-five years of petitioning — the constitutional machinery that the Revestment had silenced, slowly restarting.
The Restoration pardon that became constitutionally significant for the Isle of Man. The Privy Council ruled that the pardon extended to the Island and to all 'His Majesty's Dominions and Plantations beyond the Seas.' The power to pardon was the Crown's prerogative, not Parliament's gift. Nobody challenged the ruling because in 1663 the constitutional questions it raised could unravel the whole Restoration settlement.
The Isle of Man granted property-owning women the right to vote, decades before Westminster. The Island that had been treated as constitutionally insignificant led the British Isles in democratic reform. A measure of the constitutional vitality that survived the Revestment.
The House of Keys passed a formal resolution opposing the sale of the Island. The signatories recorded their opposition 'as much as in them lies.' Hugh Cosnahan carried the deputation to London. George Quayle would later write that they had 'silenced the neighbours but could not silence me.' Parliament received the petition and ignored it.
Passed in the same parliamentary session as the Isle of Man Purchase Act 1765. Both were Grenville measures. The Stamp Act provoked revolution in America; the Purchase Act destroyed Manx sovereignty. Twin instruments of the same imperial fiscal policy.
Act protecting the East India Company monopoly against Manx trade. Part of the legislative arsenal Westminster built to constrain the Isle of Man's economy before the Revestment.
Extended the prohibitions against Manx trade, tightening the legislative net around the Island's economy in the service of East India Company interests.
