Dyott’s father bought a cottage and close at Stychbrook, a few miles north of Lichfield in 1553.
The eldest of four sons, Dyott trained at Clement’s Inn and the Inner Temple and was called to the bar in July 1587. On succeeding his father in April 1578, he continued to expand his family’s holdings in and around Lichfield. In 1580 he bought 1,060 acres at Tamhorn and Whittington, while in 1584 he acquired a lease of Bexmore farm, in Streethay, and a further slice of Freeford manor. More of Freeford was sold to him in 1606, but the remaining tranche eluded him for another ten years. In 1610 Dyott purchased two enclosed fields in Lichfield,
Dyott married Catherine Harcourt in 1582, a match which connected him to an important west Staffordshire family and produced four sons. By 1598 he was providing the county’s magistrates with legal advice.
The Buckinghamshire election dispute was not the only issue which attracted Dyott’s attention. He also participated in the debate to decide whether Sir Thomas Shirley I, Member for Steyning, should have privilege (27 March). Shirley had been arrested at the suit of a creditor named Goldsmith even though Shirley had warned Goldsmith and the arresting officer that he was a burgess of Parliament. Dyott argued that the arresting officer had been correct to ignore Shirley’s warning because, being purely verbal in nature, it did not prove Shirley’s status, which could only have been demonstrated satisfactorily by a written record. Nonetheless, Shirley’s continued detention constituted a contempt, as a written record of his election was now available. Dyott ended by observing that Shirley’s case highlighted the existence of a legal loophole, for if Shirley were released Goldsmith would be unable to execute the same arrest warrant again, no matter how justified his grievance.
Dyott was named to relatively few committees in 1604. Apart from those already noticed, he was nominated to committees to consider Sir Edward Montagu’s motion on religion (23 Mar.); Sir Henry Neville I’s questions regarding treason and the position of the Common Law in respect of royal grants (26 Mar.); and a bill to prevent common recoveries against infants (27 Mar.), a subject which doubtless interested him professionally. On 13 June he was added to the committee for considering alterations to the Tunnage and Poundage bill in respect of Chester. Finally, on 5 July he was appointed to the bill committee for confirming letters patent.
During the interval between the first and second sessions, Dyott wrote to the countess of Shrewsbury on behalf of (Sir) William Leighton† who, like Dyott, had married into the Harcourt family and been educated at the Inner Temple. Dyott was counsel for the countess’s husband and Leighton and Dyott were engaged in a business deal together involving property in Derbyshire.
When Dyott next addressed the chamber it was on the subject of purveyance. Speaking on 6 Mar. he enthusiastically endorsed John Hare’s reform bill of January 1606, which maintained that the king’s prerogative extended only to pre-emption and not to price. He reportedly ‘ripped up again the point of prerogative, saying that in buying and matter of that kind it was nothing but pre-emption’. During the course of his ‘long, learned speech’, Dyott drew attention to the implications of Hare’s radical bill, which effectively destroyed the government’s case for composition. If the king had no right to demand goods at lower than the market price then there was no need for the House to buy out purveyance. Dyott therefore not only opposed composition but demanded that the existing laws against purveyance be enforced.
Over the course of the second session Dyott was appointed to relatively few legislative committees. Those to which he was named concerned George Ognell’s title to a Warwickshire manor (20 Feb. 1606); impositions (19 Mar.); the lands of Thomas Mompesson (1 Apr.); the letters patent of the Pinners’ Company (1 Apr.); the restitution of Roland Meyrick (Apr.); and copyhold (2 April).
Dyott was appointed to the Staffordshire bench in April 1609. He resumed his seat at Westminster in the following year, taking up residence in the parish of St. Clement Danes, where he briefly became a ratepayer.
Dyott played a minor role in the debates on the Great Contract. On 1 May, when Sir Julius Caesar asked the House to vote on whether to debate the Contract in committee, Dyott opined that a division was unnecessary, as it was appropriate to discuss the ‘matter’ in the House, leaving the ‘manner’ to a committee. He again discussed the Contract on 14 June, when he condemned purveyance, impositions and the straining of the royal prerogative, and urged the House to consider supply and support together or not at all. He said nothing more until 11 July, when the House debated the king’s demand for supply. The House had hitherto been unprepared to consider supply until it received assurances that its grievances would be redressed. James had given only a partial answer to the House’s petition for redress of grievances on the previous day, but Dyott, though he still hoped for a fuller answer, thought that this was sufficient to merit granting at least a token sum by way of gratitude. The House shared his view, and accordingly voted James one subsidy and one fifteenth. Nine days later Dyott returned to the question of the remaining grievances when he called on the king to give a full answer to the House’s earlier petition.
Dyott was named to just four legislative committees during the session. Their subjects included recusants (8 May); the lands of Reginald Rous of Badingham, Suffolk (24 May) and Chelsea College (22 June). They also included a measure to prohibit the export of iron ordnance, which Dyott was ordered to help draft after another bill on this same subject had been rejected (30 May). On 5 July Dyott was named to the joint conference for the bill to restrain canons not confirmed by Parliament. Two days before the end of the session, he and Nicholas Fuller were ordered to draft a bill in Star Chamber against a Catholic priest named Preston and the gaoler who had released him without warrant.
During the fifth and final session of the Parliament, Dyott participated in discussions on whether to accept the Great Contract. He asked the House to consider ‘what to have, whether to have it, how to have it, [and] how to levy the money’ (3 November).
In 1611 Dyott invested in the Virginia Company, but like many members of that body he paid only part of his subscription, which amounted to £37 10s.
Dyott was not a Member of the 1621 Parliament, but was named in the committee of grievances for having drafted Dr. Eglesham’s patent for gold and silver leaf, which allegedly destroyed bullion.
