Referendums are not a right. Parliament has passed no law governing when referendums must be held. Because Parliament has set itself no guidelines on when to call referendums, the public has no right to one even if similar situations in the past have warranted them. Moreover, a system of representative democracy means referendums are not necessary -- it is MPs' job to make decisions. The public have the right to vote for leaders and hold those leaders accountable, not a right to vote on individual issues.
