Matrix Chambers has an excellent reputation for handling the full spectrum of contentious and non-contentious work in the election law space. Gavin Millar KC is a highly regarded election law expert, and Helen Mountfield KC is sought after for her expertise in advising on election petitions. In recent instructions, Sarah Sackman successfully represented the respondent local councillor in Buchan v Elliott, defeating an election petition challenging the result of a Hartlepool Borough Council election - at issue in this case was if statements made on the victor's leaflets about the second-placed a minor party candidate's support for a locally controversial housing development were political or personal.

At 4-5 Gray’s Inn Square, members are very well known for their expertise in advising electoral administrators and returning officers on local, parliamentary and mayoral election matters, and are equally adept at advising the Electoral Commission, individual candidates and political parties on a broad spectrum of election law issues. Recent work includes Timothy Straker KC acting on behalf of the returning officer in a petition concerning incorrectly issued ballot papers for a parish council by-election; it was ruled that the election was conducted in accordance with the law and the result was unaffected by the error. At the junior end of chambers, the ‘extremely thorough‘ Vivienne Sedgley counts referendum matters, electoral registrations and political party disputes among her key specialisms.
