This note aims to address one of
the many constitutional issues that have arisen in the aftermath of the United
Kingdom’s referendum on its membership to the European Union. The electorate,
by a relatively slim majority, have voted to leave the EU, and in response EU
leaders have invited the UK to initiate the ‘Brexit’ process by invoking
Article 50 of the Lisbon Treaty that provides the procedure to be followed by
any member state wishing to withdraw from the European Union.
