Career
He was elected Bishop of Moray, probably in early 1299. Extended details exist regarding the election because of an extant letter of Pope Boniface VIII. The result of the election was that David had 13 votes, the Dean had 4 votes, the Chancellor had 3 votes and the Archdeacon 1 vote. The Dean declared that David was elected, and sent a request for confirmation to the Papacy.
The latter found an irregularity, though what exactly this was was not revealed.
The election result was nominally declared void, but the Pope himself provided David directly to the bishopric. He was consecrated as Bishop at Anagni in Italy on 28 June 1299, by Matthew of Aquasparta, Cardinal-Bishop of Porto.
In 1306, King Edward I of England charged Bishop David with complicity in the murder of John III Comyn, Lord of Badenoch. David was excommunicated and fled to the Earldom of Orkney.
King Edward sent a request to King Haakon V of Norway for Bishop David to be arrested.
David escaped capture. On the orders of the Pope, the Bishop of Dunblane and the Bishop of Winchester delivered a sentence of excommunication on David and other bishops on 23 May 1322. The foundation confirmed by Charles the Fair, King of the French, in August 1326.
Bishop David, however, died before the College was formally instituted.
He died on 6 January 1326, and was buried in the choir of Elgin Cathedral.
