Career
Conroy became a referee in 1993 and was admitted to the SFA list five years later. He is a regular referee in the Scottish Premier League and the Scottish Football League. On 10 March 2007, Conroy was the official for a SPL match between Hearts and Aberdeen.
During the course of the match he sent off Hearts player Laryea Kingston.
Kingston reportedly reacted to the red card by calling Conroy a racist. Conroy reported Kingston to the Scottish FA for using "offensive, insulting and abusive language".
Kingston subsequently faced a disciplinary hearing on 1 May 2007 at which the SFA decided that a further 3 game ban was in order. Conroy took charge of his first Old Firm game on 3 January 2010.
Conroy was criticised for his performance in the game after disallowing a goal from Celtic"s Marc-Antoine Fortuné for a foul on Rangers goalkeeper Allan McGregor and for showing a yellow card to Rangers striker Kyle Lafferty following a heavy challenge on Celtic"s Andreas Hinkel when Celtic fans and some reporters had argued the challenge was deemed worthy of a straight red.
On 3 December 2011, Conroy awarded a controversial penalty to Rangers in their home game against Dunfermline which Dunfermline manager, Jim McIntyre, described as "a disgrace of a decision". Conroy was subsequently assigned to referee lower division matches and opted to retire in March 2012.
