The Democratic Duty to Oppose Brexit

What should be the position of democrats in response to the Brexit referendum? Many urge a duty to accept the result. This article argues the contrary. If someone is a UK citizen, has a belief that leaving the European Union will be damaging to the common good of the UK and is a convinced democrat, then that person has a duty to oppose Brexit. Neither of the two principal reasons for accepting the result—a claim of popular sovereignty or of parliamentary sovereignty—imply a duty not to continue to oppose. Arguments from political equality for simple majority rule do not apply when the alternatives are ill defined. More generally, popular sovereignty presupposes and does not replace constitutional democracy, and in a parliamentary democracy there is always a continuing right to oppose.
