There have been suggestions recently that Labour
under Andy Burnham could put a commitment to rejoining the EU in its next
election manifesto and that, if they were to be elected, that would constitute
an adequate mandate for the government to act without any need for a
referendum. The Brexiteers are unsurprisingly less than happy at such a prospect,
but legally and constitutionally, those making the suggestion are entirely
correct: there are no circumstances under which the unwritten constitution of
the UK requires a referendum to be held. Indeed, by way of precedent, there was
no referendum held when the UK joined the EEC back in 1973. The ‘confirmatory’
referendum held in 1975 following a change of government was always more about
politics (and internal Labour politics at that) than the law or the
constitution. Actually, it doesn’t even follow that a manifesto commitment is
required either (although as it happens the then-Tory
government had included the commitment in its 1970 manifesto). Had it not been
for de Gaulle’s veto, the UK might have joined when it first applied in 1961,
and there was no commitment at all to such a course of action in the 1959 Tory manifesto
– indeed, the emphasis had been on the alternative, EFTA.
Ultimately, it’s a question of politics, not law.
Would it be wise for any UK government to take the UK back into the EU without
holding a referendum first, especially if such a government were to have been
elected on a minority share of the vote under the UK’s antiquated electoral
system? Unless it could be clearly and unambiguously demonstrated that public opinion
was overwhelmingly supportive of membership, the answer surely has to be a firm
‘no’, not least because a parliamentary majority one way could be reversed at
the following election, turning the UK into a sort of hokey-cokey member of the
EU.
Much the same arguments also apply to the question of
Welsh or Scottish independence. No referendum is required, either in domestic
law or in international law: all that is required is that the countries have effective
governments which are actually are in control and that independence is
recognised by the international community. As with EU membership, that’s not to
argue that there should not be a referendum. It is merely a recognition
that, whilst holding a referendum which produces the ‘right’
outcome might help in gaining that recognition, it is in itself neither an
essential nor a sufficient condition. And, if Burnham finally climbs down off
the fence in relation to Proportional Representation, we will also face a
similar question again.
Whether holding a referendum which reduces complex issues
to a simple yes or no is ever the best way of taking a decision is an open
question, although there are certainly circumstances where it might be the least
worst option. But leaving the decision as to whether one should be held or not
to politicians sometimes seems to be an even worse option than electing them to
take the substantive decision themselves – their decisions generally seem to be
based on the arbitrary question of whether they think they will win or not. The
simplest objective rule to employ would be that a referendum is required when,
and only when, it is proposed to change the constitution. But as long as we don’t
have a clear one of those, that doesn’t help. I don’t doubt that an independent
Wales or Scotland would rapidly write a formal constitution – I have no idea
what, if anything, would ever push England in the same direction.
