Sir Charles Calthorpe (c.1540–1616 ) was an English-born judge in Jacobean Ireland. Prior to his appointment to the Irish Bench he had been Attorney General for Ireland for more than 20 years. He was a close associate of the Lord Deputy of Ireland, Sir John Perrot, and Perrot's downfall damaged his career, but he was eventually restored to favour.
He belonged to an old Norfolk family; his father was Francis Calthorpe of Hempstead and his mother was Elizabeth Berney of Gunton. He entered Lincoln's Inn in 1560. He gave readings on the law of copyhold at Furnivall's Inn which were published in 1562. He was called to the bar in 1569 and became a Bencher of his Inn in 1582. He sat in the House of Commons as member for Eye in the Parliament of 1572. In 1584 he became Attorney General for Ireland and quickly became a supporter of the Lord Deputy, Sir John Perrot. From the outset of his time in Ireland Calthorpe was subject to intense criticism, being accused of partisanship, insufficient learning and undue deference to his Irish colleagues. Criticism mounted after Perrot's recall in 1588, but Calthorpe managed to retain office, possibly due to the perennial difficulty in finding a suitable replacement.
Calthorpe married firstly Winifred Toto, daughter of the celebrated Italian-born painter Anthony Toto, who was Serjeant Painter to Henry VIII and Edward VI. She died in 1605. He married secondly Dorothy Deane, who had been twice married already; she outlived him by a few months. He had no children by either marriage.
The final downfall of Perrot, who was convicted of treason in 1592 and died in the Tower of London, had major repercussions in Ireland. His close ally Nicholas White, the Master of the Rolls in Ireland was arrested and like Perrot he died in the Tower: it was widely expected that Calthorpe would suffer a similar fate. He was accused of corruption by two dubious characters: Henry Bird, a former royal clerk, and an eccentric ex-priest called Denis O'Roghan. Bird had been convicted of forging Perrot's signature on O'Roghan's evidence:  Calthorpe had prosecuted the case with great vigour and there is no reason to doubt that he believed Bird guilty. O'Roghan however retracted his evidence and made charges of treason against Perrot. Sir William Fitzwilliam, the new Lord Deputy, set up an inquiry, but O'Roghan's charges were so wild that it seemed doubtful whether the inquiry could proceed. A second commission of inquiry was then set up into the manner in which the charges were made. Calthorpe sat on the commission, which proved to be a serious mistake when O'Roghan accused the commissioners of subjecting him to torture.
Fitzwilliam was now ordered to resume his own inquiry, and Calthorpe faced two serious charges: wrongly pressing for Bird's conviction, and acting corruptly in the examination of O'Roghan. He was suspended from office between 1590 and 1592, and it was widely believed that he would be prosecuted. In February 1591 he wrote to Burghley pleading for his protection. Given that Burghley was a close associate of Fitzwilliam, he might seem an unlikely patron of Calthorpe, but he was generally inclined to moderation, and in the event it was decided that a severe censure of Calthorpe's conduct was a sufficient penalty. He also suffered the embarrassment of seeing the conviction of Henry Bird publicly reversed. He was restored to office in the autumn of 1592, but his reputation never fully recovered.
In 1594 the Court of Exchequer (Ireland) was asked to rule on whether Sir Thomas Molyneux, the Chancellor of the Exchequer of Ireland, was eligible for public office. Molyneux, though of English origin, had been born and raised in Calais and lived for some years in Bruges; his enemies suggested that he was a foreigner and a Roman Catholic. Calthorpe, having questioned Molyneux, informed the Court that he was a Protestant Englishman, and as such qualified to hold public office.
Calthorpe, began pressing for promotion to what he presumably hoped would be the less stressful life of a High Court judge. He was offered the position of Chief Justice of Munster, but refused it (the work of that office was extremely onerous, and clearly did not appeal to him) and sought the office of Chief Justice of the Irish Common Pleas instead. On hearing that the salary of that office was to be reduced he withdrew his application. In his later years he seems to have neglected his duties at the Attorney General's Office: in 1604 he was living in London, and the following year Sir Arthur Chichester, the new Lord Deputy, complained of his inefficiency, although he was given a knighthood the same year. The decision to appoint Sir John Davies as Attorney General made it desirable to find a promotion for Calthorpe, and in 1606 he finally reached the Bench as a judge of the Court of Common Pleas (Ireland). He was not a success as a judge : in 1611 he was described as old, weak and unable to serve, although he remained on the Bench until his death. He died in January 1616 and was buried in Christ Church Cathedral, Dublin.
Calthorpe was judged harshly in his own time, but he has been viewed more favourably by recent historians. As Crawford points out the whole judicial process leading to the disgrace of Perrot was deeply political, and Calthorpe, as one of Perrot's closest allies, could not have hoped to escape censure. Despite the abuse heaped on him, it is notable that he retained office for 22 years. Casey praises him for his constructive and business-like management of the office, although Chichester's criticisms suggests that he let matters slide in his later years.
