This problem had been surmounted by the landlord issuing a lease renewable for ever in return for a combination of a substantial part of the value of the estate and a fixed annuity. However, the lease had to be periodically renewed and certain nominal conditions met at that time.
Many of these leaseholders had become casual about their renewals; and as the conditions had not been met while land values substantially increased in the course of the century, the original owners were tempted to challenged the validity of these leases. Lord Chief Justice Mansfield had upheld the letter of the law and chaos was narrowly averted when the old equity was restored by an immediate act of parliament, 19 & 20 Geo. III, c. 30 (0897).
Many Irish landlords saw advantage in the English verdict, and the remedial legislation passed by only two votes in the House of Commons and one in the House of Lords, where Lord Strangford, an impoverished peer and cleric, was reputed to have sold his legislative vote for 40 years. The Declaratory Act was repealed in 1782 and the right formally renounced in 1783. There followed a notorious bribery case, as Lord Strangford attempted to sell his judicial vote on the Rochfort–Loftus case (1256, 1801, 2088) and a wrathful parliament excluded him for ever, 23 & 24 Geo. III, c. 59 (1041)!
Until the early 1780s the twin questions of legislative independence and appellate jurisdiction remained a cause of smouldering resentment. In the first quarter of the century the British government tried to suppress the argument, but it flared up from time to time, triggering a demand for Molyneux's book. For the two decades following the 1720 Declaratory Act Swift was to be the principal torch-bearer for Irish colonial nationalism.
In A proposal for the universal use of Irish Manufacture, published in 1720, he declared his own and his class's objections to British attempts to secure Ireland's constitutional dependency. This pamphlet advocated, inter alia, sanctions against English imports through an exclusive use of Irish goods. This became a recurrent theme, especially in times of political agitation or economic depression.
