In 1973, the UK government organised the country’s first referendum, on the subject of whether or not Northern Ireland should remain part of the UK. Now, as Brexit and its potential consequences make another border poll look like an increasing possibility, David Torrance looks back on the poll, its background, and its later constitutional significance.

Introduction 

The first constitutional referendum in the history of the United Kingdom took place on 8 March 1973. It was held nearly four years after the beginning of ‘The Troubles’ – a sharp deterioration in the security and political situation in Northern Ireland. 

What became known as the ‘border poll’ (although it was also called a ‘referendum’ or ‘plebiscite’, no one could quite agree on terminology) emerged as a means by which to ‘take the border out of politics’, or so it was hoped. In discussions with the Government of Northern Ireland (NIG) on 22 March 1972, the UK government proposed transferring responsibility for law and order from Belfast to London, phasing out internment, and periodic plebiscites.

The last two were, in principle, acceptable to the NIG, but an erosion of its ‘transferred’ powers under the Government of Ireland Act 1920 was not. The Prime Minister of Northern Ireland (Brian Faulkner) and his Cabinet later resigned, and on 30 March the Parliament of Northern Ireland – known as ‘Stormont’ – was prorogued and Direct Rule from Westminster introduced for the first time since 1921.

Speaking in the Commons on 24 March 1972, Prime Minister Edward Heath said:

‘We… propose in due course to invite Parliament to provide for a system of regular plebiscites in Northern Ireland about the Border, the first to be held as soon as practicable in the near future and others at intervals of a substantial period of years thereafter.’

In effect, Heath was proposing to transfer the principle of ‘consent’ from the prorogued Parliament of Northern Ireland (enshrined in the Ireland Act 1949) to its people, ‘the Border’ representing a proxy for a much broader constitutional question.  Continue reading →
