This Member’s background is so obscure that he has previously been mistakenly identified as Welsh in origin.
Early in 1604 Dunne attended the Hampton Court Conference, where he argued in defence of ecclesiastical courts.
In the second session Dunne was among those instructed on 5 Nov. 1605 to consider the Spanish Company patent, before the Gunpowder Plot interrupted proceedings.
The Union with Scotland occupied Dunne’s attention almost exclusively in the third session. In debate on the post-nati, he was of the opinion, as a civilian, that the king had power to naturalize by Proclamation, as he argued on 23 Feb. 1607.
On the death in February 1609 of his fellow Member for Oxford University, Sir Thomas Crompton*, Dunne was appointed judge of the Admiralty Court alongside Richard Trevor. When Parliament reassembled in 1610 for its fourth session he was appointed to attend the conference with the Lords of 15 Feb. at which the lord treasurer unveiled his plans to reform the king’s finances. He was subsequently instructed to help prepare for a conference on the authoritarian writings of the civilian Dr. Cowell (27 February).
In 1611 John Chamberlain reported that Dunne ‘grows old, and hath resigned his place of Requests, or at leastwise his waiting’.
On the death of Richard Trevor in June 1614, Dunne became sole judge of the Admiralty Court. He remained in office until he died, intestate, on 26 Sept. 1617. He was buried at Theydon Garnon, being described by Chamberlain as ‘no rich man for all he had three good offices’, presumably as a result of having to provide dowries for his numerous daughters.
