Dunlop lodged a controverted election petition with the Legislative Assembly. Colonel John Prince, the member for the neighbouring riding of Essex, acted for Dunlop in moving the matter through the Assembly. Two months into the session, during which Strachan participated as a member, the Assembly allowed Dunlop's appeal, ruling that unqualified voters had been allowed to vote in favour of Strachan. Dunlop was awarded the seat on 20 August 1841, replacing Strachan. Dunlop sat as member for Huron for the duration of the first Parliament.
