Understanding advisory referendums, and where they fit within our constitution


In the wake of the 2016 Brexit referendum, much has been written on the use (or abuse) of advisory referendums on plainly 'constitutional' issues.  These might be referendums on secession, the transfer of legislative powers, devolution, or voting reform.  Early understandings are beginning to form on how these exercises are to be understood by the law (versus a purely political understanding), and how the common law constitution might circumscribe their use.  Indicative of this, the issue of ‘constitutional’ referendums has been considered by the House of Lords Constitution Committee. 

However, very little has been written about advisory referendums which are not on constitutional questions.  Australia’s 2017 ‘plebisurvey’ on LGBTI civil rights, earlier votes on pub opening hours or business trading times, and New Zealand’s upcoming referendum on euthanasia, are all examples of public votes on what are classically understood to be ordinary policy issues.  Matthew’s research focusses on how this species of referendum – the ‘policy referendum’ – is to be understood, and where such exercises fit within the Westminster constitutional architecture.  The basic question addressed is whether the law has anything to say, or ought to have anything to say, about the use (or abuse) of popular votes of this kind, and the potentially hidden role these votes might play in constitutional change. 

His research draws on UK and Australian public law, adminsitrative rights and remedies, questions of standing and public interest litigation, and more theoretical understandings of political power and the constitutuent sovereign.
