The claimant sought to challenge the decision by respondent not to offer a referendum before acceding to the Treaty of Lisbon. The claimant’s case was that the Government’s promise to hold a referendum in relation to the European Union Constitutional Treaty gave rise to a legitimate expectation that a referendum would be held in relation to the Lisbon Treaty.
Lord Justice Richards said: ‘We have expressed ourselves cautiously on the materiality of those various differences between the Constitutional Treaty and the Lisbon Treaty. We have done so because there is a further and deeper difficulty facing the claimant in relation to this issue. The court is in a position to determine the extent of factual differences between the two treaties, but how is it to assess the materiality of the differences that it finds? Whether the differences are sufficiently significant to treat the Lisbon Treaty as falling outside the scope of an implied representation to hold a referendum in respect of a treaty ‘with equivalent effect’ must depend primarily, as it seems to us, on a political rather than a legal judgment. There are, as Mr Sumption submitted, no judicial standards by which the court can answer the question. The wide spectrum of opinion, both within and outside the United Kingdom, to which the parties have drawn the court’s attention with regard to the extent of similarity or difference between the two treaties serves to underline the point.’
