A by-election was held for the New South Wales Legislative Assembly electorate of South Sydney on 4 June 1887 because Bernhard Wise (Free Trade) was appointed Attorney General in the fourth Parkes ministry.[1] Such ministerial by-elections were usually uncontested. Most of the ministry was not required to face a by-election as they had been appointed prior to the general election in February 1887. William Foster had been the Attorney General however he resigned on the ground that he had been promised an appointment to the Supreme Court and Henry Stephen had been appointed instead.[2]
With a margin of just 40 votes, William Traill challenged the result in the Elections and Qualifications Committee.[5] The Committee consisted of 2 Free Trade members (William Trickett and Charles Garland) and 3 Protectionist members (James Garvan, Thomas Slattery and Henry Clarke).[6] The committee scrutinised the ballot papers and held that Wise was properly elected, finding that the true result was Wise 2,611, Traill 2,571, formal 5,182, informal 62, total 5,244.[4]
