A proposed Royal veto of the appointment of bishops was a contentious topic in the politics of the United Kingdom, in the period 1808 to 1829. According to the proposal, any restoration of the full episcopal hierarchy of the Catholic Church, in Great Britain, should be subject to a veto of the Crown over the appointment of any bishop whose loyalty was suspect.
The matter was eventually resolved by the passage of Catholic Emancipation without such a condition.
Although the penal laws enacted against the Catholics of Ireland and of Britain were still on the statute book towards the close of the eighteenth century, they were less strictly administered than before. Several causes helped to bring this about. The Catholics formed the vast majority of the population of Ireland. Their sympathies were thought to be with the French whom Britain had at that time cause to fear.

In connection with the Union, William Pitt intended to bring in a Catholic Relief Bill. He commissioned Lord Castlereagh to make such arrangements as would satisfy the king George III of Great Britain that no priest whose loyalty the king should have reason to suspect would be appointed to an Irish bishopric. Ten bishops, trustees of Maynooth College, met on 17 January 1799, to transact college business. Castlereagh submitted his views to them, reminding them of the suspicion of disloyalty under which the Catholics of Ireland lay since the insurrection of the year before. The ten bishops embodied their reply in certain resolutions, of which this was one:
