Named after a Norman constable of Chester, the Constables acquired Flamborough by the end of the twelfth century.
After Constable’s father died in 1600, his lands were leased to William Skipwith of Lincolnshire, who assigned his interest to Sir Henry Slingsby*, owner of a neighbouring estate; the latter also purchased the wardship for £114, though he surrendered custody to Constable’s uncle Sir William Fenwick in 1605.
Appointed custos of the East Riding bench shortly after attaining his majority, Constable was one of the justices Sir Thomas Hoby* accused of conspiring to prevent his indictment of suspected recusants at the Epiphany sessions of 1615. The only substantive charge Hoby brought against Constable was that he had adjourned the court for lunch despite the disapproval of a (largely puritan) minority. The clerk of the peace testified that Constable had been ‘much moved that such difference should arise upon so small occasion’, and given his later godly reputation, Constable’s anger was probably aroused by the fact that Hoby, custos of the North Riding, had presumed to interfere in his jurisdiction. After extensive proceedings, the case was apparently dismissed.
At the 1626 general election Constable stood as knight of the shire in place of his father-in-law, who had sat in the previous Parliament. Sir Thomas Wentworth*, fearing that ‘unless Sir William Constable stand, a great part of the East Riding will voice with [Sir John] Savile’*, arranged a pairing with Sir Francis Wortley*. Savile secured the senior seat, but Constable was returned for the junior, his rival’s son Sir Thomas* having stepped aside on the morning of the contest following a conveniently timed bout of ill-health.
On 15 Sept. 1626 Constable was removed from the East Riding bench, more because of his opposition to Savile, now in favour at Court, than any conspicuous hostility to the duke of Buckingham.
At the 1628 election Constable was thought to have designs upon the county seat once more, but any such intentions were ended by Fairfax’s suggestion of a pairing between Henry Belasyse* and Wentworth. In return for this concession, Wentworth apparently used his contacts with William Coryton* to find Constable a seat at Callington, Cornwall, where the dominant interest was held by John Rolle*.
Constable’s confinement as a Loan refuser hardened his opinions. In the subsidy debate of 4 Apr. 1628 he advocated a modest grant of four subsidies and scorned the Crown’s verbal promises to refrain from arbitrary measures: ‘methinks our confidence and assurance for our own safeties hath not been enough pressed. As we invoke no conditions in our gift, so I hope we may the [more] confidently expect assurance of grace, if not merit’. This mistrust of the royal prerogative surfaced again on 20 May, in a debate on the Lords’ amendments to the Petition of Right. The Lords objected to the description of the oath administered by the Forced Loan commissioners as ‘unlawful’, and suggested ‘not warrantable by the laws’ as an alternative. John Selden and John Glanville, both eminent lawyers, assured the House that the difference was merely semantic, but Constable suspected that the alteration might imply ‘a tacit concession that such a thing may be put upon us by some means above the law’. He made one more recorded speech during the session, on 5 June, supporting the naming of Buckingham in the Commons’ Remonstrance, in defiance of the king’s express wish, and reminding his colleagues that ‘the last Parliament this House made a protestation that while this man continued we could not look to prosper. We have seen the events; wished to do so again’.
Wentworth’s rise to power at Court in the autumn of 1628 secured Constable’s restoration to local office, and probably explains why he was less prominent in the 1629 session.
Constable was summoned before the Privy Council in October 1630 to explain his failure to compound for neglecting to present himself for knighthood at the coronation; but he apparently escaped without payment.
Constable subsequently remained near London, and at one point visited Great Missenden in Buckinghamshire, presumably at the invitation of the Fleetwoods, to whom his wife was distantly related. He also undertook negotiations for the marriage of his wife’s nephew, Sir Thomas Fairfax†.
By 1640 Constable and Boynton were members of a separatist congregation at Arnhem led by the millenarian John Archer.
