During the
English Civil War, Domville's loyalty to the Crown was never seriously questioned. His decision to practice law in England under the regime of
Oliver Cromwell was not an unusual one even for a committed Royalist, and was not held against him later, since other Royalists had also made their peace with the new regime when the King's cause seemed to be lost. He lived then at
Friern Barnet in
Middlesex. At the
Restoration of Charles II he returned to Ireland, and was
knighted and made Attorney General, apparently on the recommendation of
Daniel O'Neill, an Irish
Groom of the Chamber to Charles II who had considerable influence in the first four years of the reign. He entered the
King's Inns in 1661. He received a substantial grant of lands at
Templeogue, on the outskirts of Dublin city, which remained in the family for centuries. The value of the lands was greatly enhanced by the fact that the
River Dodder flows through them, thus giving the Domvilles partial control of the supply of Dublin's drinking water, of which the Dodder was long the principal source. Strictly speaking, they had no right to control the supply of water; this power was vested solely in
Dublin Corporation. Domville also had a townhouse in Bride Street, and was granted the estate at
Loughlinstown which had been forfeited by the Goodman family. He was elected to Parliament as member for
County Dublin, and was the Crown's choice as Speaker. He faced opposition from the able and ambitious
Prime Serjeant, Sir
Audley Mervyn, who, apparently by spreading the story that Domville was sympathetic to
Roman Catholics, gained the support of the majority of MPs (in fact Domville was a strong Protestant, although personally tolerant enough in matters of religion). The King, who was anxious to avoid a confrontation with Parliament so early in his reign, stated that the choice should be that of the members, and Mervyn was duly elected Speaker.
Domville's struggle for precedence with Audley Mervyn The next few years saw a struggle between Domville and Mervyn for the role of principal legal adviser to the Crown. Domville emerged as the winner: both the King and the
Lord Lieutenant of Ireland,
James Butler, 1st Duke of Ormonde trusted him, whereas Mervyn had a reputation for
corruption and his loyalty to the Crown was suspect. From about 1663 onwards Ormonde simply ignored Mervyn, and took legal advice only from Domville. This marked the effective end of the Prime Serjeant's role as chief legal adviser to the Crown and the start of the supremacy of the Irish Attorney General. Domville personally prosecuted
Florence Newton for
witchcraft at
Cork's assizes in 1661, and prosecuted some of those involved in the plot by
Thomas Blood to seize
Dublin Castle in 1663. Domville was heavily involved in advising on the drafting of the
Act of Settlement 1662, although he argued that his proper task was to "criticise" the Bill, rather than to draft it (the present practice is that the
Attorney General of Ireland both "criticises" i.e. advises on any legal difficulties with a Bill, and also oversees the drafting, which is done by his officials). Domville admitted to finding the task one of great difficulty, yet he is said to have shown an unequalled mastery of the legal principles applicable.
Last years On at least two occasions he refused a place on the High Court bench. It is said that he would have been willing to be
Lord Chancellor of Ireland, but he was not offered the position. After the death of Charles II, Domville was retained in office briefly by
James II before being replaced by
Richard Nagle at the end of 1686. He was a staunch Protestant, though tolerant by the standards of the time, and it has been argued that he was seen as an obstacle to the aggressively pro-Catholic policy of the new regime; on the other hand, he may have been quite happy to retire, in view of his advanced age. He died in July 1689 and was buried in
St Patrick's Cathedral, Dublin. ==Political views==
