The Lord Deputy,
Arthur Grey, 14th Baron Grey de Wilton, has been described as seeing his role of Deputy as "a largely military one". Perhaps for this reason the unusual decision was taken to conduct Nugent's trial for treason in a manner which, according to critical historians, "had the appearance of
martial law". It was held in
Trim, rather than Dublin, allegedly for convenience, and Grey appointed a special commission to assist him, which included Sir Robert Dillon, his cousin the Chief Baron
Lucas Dillon, and
Richard Segrave, who had replaced Nugent on the Court of Exchequer. In contrast to the modern view that judges should come to a case without bias, these men seem to have been chosen precisely because they knew Nugent personally. He did however have the benefit of
trial by jury in the normal way. Nugent, like all those charged with treason in Ireland until the middle of the eighteenth century, was denied the right to
legal counsel, but given his own legal expertise this was presumably less of a difficulty for him than it would have been for a layman, and he conducted his own defence with great spirit. He accused Robert Dillon of having bribed Cusack to commit
perjury, and it seems that much of the trial was taken up by Dillon defending himself against charges of misconduct. To bolster the evidence, Grey claimed that Nicholas had privately confessed his guilt to Mr Waterhouse, a royal clerk. Whether or not the judges came to the trial with their minds made up, they seem to have had little doubt as to the verdict which the jury should bring in. According to later reports the jury wished to acquit Nugent, and it required considerable efforts by the judges to make them convict. Nugent was found guilty, along with his co-accused Edward Cusack, and hanged at Trim on 13 April. There were claims that the jury were coerced by the judges, which is likely enough.
John Philipps Kenyon writes that until the 1670s it was considered quite proper for a judge to bring strong pressure on a jury to find the "right" verdict (i.e. guilty), and the practice of a judge "suggesting" that the jury bring in the required verdict continued into the 1690s. Further, the jury would probably have been aware that the Crown had the right to punish jurors for acquitting an accused person in the face of strong evidence of their guilt, as would happen to a
County Kildare jury in 1586. ==Aftermath==
