The leading light of the Scottish bar and the white hope of Scots Whigs, Erskine was in ‘universal requisition’, and as Lord Cockburn recalled, ‘Nothing was so sour as not to be sweetened by the glance, the voice, the gaiety, the beauty of Henry Erskine’. ‘He reasoned in wit’ and his name ‘suggests ideas of wit’. All this was lost on Westminster, where he appeared only for a year, late in life, as lord advocate. He had held the same appointment in the coalition ministry of 1783, but went out of office unprovided with a seat in Parliament. Subsequently he was the chief inspiration of the Independent Friends, as the Scottish Whigs demurely styled themselves, and leader of their campaign to redeem their plight. He remained the Prince of Wales’s advocate in Scotland and his professional situation was further enhanced by his election to succeed Henry Dundas as dean of faculty in 1785, but in political management he was easily outmanoeuvred by Dundas, who left no stone unturned to thwart him. Had his friends returned to power in the Regency crisis, he was to have been restored as lord advocate and was confident that in close co-operation with Sir Thomas Dundas he could lead the Scottish Whigs to victory. The political survey of Scotland drawn up for his use by Lawrence Hill, WS, in 1788-9 inspired sanguine hopes in him.
Erskine’s leadership of the movement to oppose the treason and sedition bills in Scotland, revealed at a public meeting at Edinburgh on 28 Nov. 1795, brought down on him the wrath of Henry Dundas, to whom reports had been trickling through of his stirring up an opposition in the county of Midlothian. At the annual election for dean of faculty Erskine found himself opposed by Robert Dundas and defeated by 123 votes to 38. Henceforward he was a Whig martyr, cried up by William Adam, toasted by Fox and acclaimed a member of the Whig Club, 8 Nov. 1796.
Erskine’s prospects were changed when his friends came to power in 1806. He wrote to Fox, 13 Feb. 1806, a polite notice that the Scots Whigs would not tolerate the maintenance of Lord Melville’s regime in the interests of ‘political expediency’, and expected ‘a just retribution to individuals’ and the removal of ‘the Melville faction’ from place. Lately he had been reported to be pressing to succeed the allegedly dying Lord Frederick Campbell as lord clerk register, but Lord Frederick had no wish to die and Erskine was destined for the lord advocate’s gown in the Grenville administration, in which his brother Thomas was lord chancellor of the realm. When he kissed hands, the following exchange with the King allegedly took place:
George III: ‘Not so rich as Tom, eh?—not so rich as Tom?’
Erskine: ‘Your Majesty will please remember my brother is playing at the guinea table, and I at the shilling one.’
He still had no seat in Parliament. He had hopes of Linlithgowshire, but not even the Prince of Wales could persuade Lord Moira to espouse his cause there: it was too much of an open confrontation with Lord Melville and would serve as a pretext for a vendetta. Meanwhile Lord Lauderdale made a vacancy for him at Haddington Burghs, the sitting Member being in the West Indies.
Erskine took his seat on 22 Apr. and voted for the repeal of the Additional Force Act, 30 Apr. 1806. Soon afterwards he was reported to have set his sights on the city of Edinburgh, whereupon Melville’s ‘romantic’ reaction was, that if no worthy opponent to him could be produced, he was prepared to consider supporting Erskine, ‘if he would come to a clear understanding upon it and not interfere in the interior of town administration or politick’.
The Scottish judicature bill, introduced by Lord Grenville in the Lords, 16 Feb. 1807, never reached the House. Erskine’s role in debate had been hitherto confined largely to the defence of the ministry’s military plan and its application to Scotland, May-July 1806. His only official exhibition was the Scottish clergy bill, transferring the audition of augmentations from the overloaded court of session to the Exchequer court. His most vehement speech was in favour of a bill to give creditors of the landed gentry their due, 18 Mar. 1807. By then he was ‘sadly out of humour’ with the turn of events against the ministry.
This was more or less the end of Erskine’s public career, though he remained a judicial reformer and his Whig friends thought it would be ‘cruel’ to pass over him for lord advocate if they returned to power. In May 1811 William Adam had the Prince Regent’s authority to propose him to Lord Chancellor Eldon as lord president on the death of Blair: Eldon’s reaction was that ‘fitness not politics should be the rule’. The official view of his ‘utter unfitness’ from a professional standpoint ruled out his obtaining either the presidency or the office of lord justice clerk and dictated the promotion of his juniors. Lord Moira commented: ‘Policy forbids party proscription to be avowed as such at any time’, but it was privately admitted.
