Dundas, the fourth of a line of distinguished lawyers, was brought up as an anti-Walpole Whig, sharing his father’s antipathy to Islay as manager for Scotland. A high-spirited, sociable young man, he returned home in November 1737 after four years’ study abroad with little taste for literature or metaphysical subtleties, but a keen determination to gain fame and fortune at the Scottish bar. His marriage to an heiress worth £2,000 p.a. was a turning point in his career. ‘In money it made me independent, set me out in a high sphere of life and laid the foundation of all my future success.’
On Walpole’s fall he obtained, through his father’s connexion with Tweeddale, the office of solicitor-general under the Wilmington Administration, working in close harmony with his friend Andrew Mitchell. After the outbreak of the ’45 he was obliged to flee from Edinburgh to Berwick; he returned in November 1745 but, bitterly at odds with Lord Justice Clerk Milton and the Argyll party, resigned with Tweeddale in January 1746, much against his father’s wishes.
He resumed his lucrative bar practice and, disgusted with politics, refused to stand for Edinburghshire at the 1747 election. Connected through his wife with Hyndford and Findlater, hitherto inimical to his father, Dundas did not share his dislike of Newcastle and Pelham, but again in 1750 declined to contest Lanarkshire, though assured by Charles Hope Weir of Pelham’s support.
Mr. Dundas of Arniston and I are in all human appearance on a very good footing; he was so good as to say ... that he would not stand unless I approved of it. He came to see me at Edinburgh and I then returned the compliment by begging him to stand ... We have since corresponded ... [on] the great utility it would be to the Government if we could make peace and prevent quarrels among the Whigs of distinction; he seems to be a sensible pretty kind of man; but some of his own friends say he is as hot as his father, though I think that cannot be true to such an extent.
After Dundas’s unopposed return, his friend General Bland, commander-in-chief in Scotland, urged Hardwicke and Newcastle to promote William Grant to the bench and appoint Dundas his successor as lord advocate. ‘The business of the Crown suffers by not having an able man ... who is solely attached to the King and owes his preferment purely to the English ministers and not to any of the leading men here.’ On receiving the office Dundas showed his anti-Jacobite zeal by a tour of investigation in the Highlands, and wrote to Hardwicke, 14 Sept.: ‘I have the satisfaction of believing myself detached from every private party or faction.’
Neither the favours nor frowns of the great men in this country can bias him from telling the truth ... He is free from the underhand low cunning peculiar to his countrymen, an enemy to the jobbing so much practised ... to the destruction of justice and the ruin of this kingdom.
Newcastle and Hardwicke, equally impressed by Dundas’s competence, concerted with him the Scottish legislation for the session. His chief task was to introduce and carry through the Government bill for continuing indefinitely the expiring Act of 1747, under which sheriffs depute were appointed during pleasure. Dundas himself had originally been opposed to the principle but for some two years past had been convinced of its necessity. But when he ably moved the bill on 20 Feb. 1755 the occasion was not a triumph for him but for Gilbert Elliot, whose brilliant opposition forced the ministry to a compromise. Alarmed by the support gained by ‘the Scotch Cabal’, the ministry dropped three other controversial bills which Dundas was to have introduced, but expressed ‘entire satisfaction’ with his conduct. Hardwicke wrote to Lord President Craigie, 1 Apr. 1755:
His great knowledge, politeness and candour have amply recommended him to all friends of Government and gained him a thorough confidence; and in the House of Commons he has succeeded beyond expectation for so short a time.
Add. 35448, ff. 174, 245.
At the end of March Dundas was summoned home by the illness of his wife, whose death in May deprived him of control of the Baillie-Carmichael fortune. ‘In an awkward and ticklish situation’, with his paternal estate encumbered with debt, Dundas applied to the Government for provision for his stepmother and her family, as compensation for his father’s losses in the ’15.
This being given to one known to be under my influence increases ... your Grace’s interest and weight ... It is well known that I have declared my principles of promoting your Grace’s interest and influence ... and that I depend entirely on your countenance and support. Since my return to Scotland these declarations are not agreeable to many.
He was bitterly chagrined when Newcastle, alarmed by the gathering opposition to the subsidy treaties, called off all attempts to undermine Argyll’s authority, and instructed Dundas to wait upon the Duke and ‘give him full assurance of acting in concert with him to strengthen Administration and cultivate harmony among all the King’s servants in Scotland’.
In the new session Dundas spoke on 2 Dec. against the Opposition bill for speedily manning the navy, refuting charges made by Gilbert Elliot concerning the Scottish press gangs. A fluent and forceful speaker, he was listed by Walpole among the 30 outstanding orators in the House, but few speeches of his are recorded.
He retained his office under the Devonshire-Pitt Administration, but remained faithful to Newcastle and voted in his defence in the debate of 2 May 1757 on the loss of Minorca. Under this Administration he concentrated on his official work in Scotland, and in Church affairs further incurred the enmity of the liberal minded by his condemnation of Rev. John Home as the author of ‘Douglas’, and of the clergymen who attended theatrical performances. Alexander Carlyle attributed his conduct to bigotry, ‘want of taste, ... a certain violence of temper which could endure no one that did not bend to him’, and to his jealousy of Sir Gilbert Elliot and Milton, warm partisans of Home.
Dundas was absent from Parliament for most, if not all, of the 1757-8 session;
During the summer of 1759 Dundas, although not concerned in the Bute-Argyll quarrel, became alarmed by Charles Townshend’s attempts to make capital out of the affair, and to gain through Milton an ascendancy in Scottish affairs, particularly when the Dundas interest in Midlothian was threatened by a proposal to set up John Dalrymple, Townshend’s friend, as candidate at the next election.
Disapproving from its inception the agitation for a Scottish militia bill, which he believed would provide arms for the disaffected, he did not openly oppose it.
Our friend the advocate is a man of that spirit and resolution that he will always speak his opinion whatever the consequences ... But as I love the man I cannot but think the conjunction was unfortunate, and I should be sorry if those who do not wish him well succeed in making people in general think that the part he acted proceeded more from motives of interest than conviction. Whatever unpopularity may arise from his opposition to the militia bill his ... upright conduct in the seat of justice will in a short time acquire him the good opinion of his fellow subjects.
Dundas proved, indeed, the most able and energetic president of the century. He remained connected with Newcastle, who in 1765 offered him the management of Scotland ‘in some shape or other’ under the Rockingham Administration. This Dundas declined as ‘improper for any judge’.
He died 13 Dec. 1787.
