Polling was conducted on 9 April 1856. Manning had served in the old Legislative Council as an appointed member. Unlike other newly appointed Ministers, he did not have to resign and contest a ministerial by-election as he already held the office of Solicitor-General at the time of his election. Weekes was elected, but later won an appeal against his defeat in Northumberland Boroughs, choosing to sit for that seat and resign from this seat. The subsequent by-election was won by Brenan.
