The Recorder was the chief magistrate for Dublin, and heard a wide range of civil and criminal cases.
From information given during a debate on the duties of the Recorder in the English House of Commons in 1831, it seems that he sat twice a week, with extra sessions as and when the workload required.
Nonetheless, Sir Frederick Shaw, the Recorder in question, continued in his dual role for many years, until he stepped down as MP in 1848.
He had clearly held the office in the previous year, when like all the Irish judiciary, he had supported the attempt by the pretender Lambert Simnel to claim the English Crown, and following Simnel's crushing defeat was now required to do penance for his treason and swear fealty to the Tudor dynasty.
His disgrace was short-lived: Sir Richard Edgcumbe, who administered the oath of fealty to him, dined with him "with great cheer".
