The Assange saga continues with recent decisions in the English Courts upholding the warrant for Julian Assange’s arrest. Dapo’s recent post on Ecuador’s purported appointment of Julian Assange as one of its diplomats to the UK considered the position on this issue as a matter of international law. However, a related issue is how the relevant provisions of the Vienna Convention on Diplomatic Relations (VCDR) would be applied if the issue were to arise in domestic proceedings in England and Wales. In other words, if Assange were to leave the embassy, and were to be arrested and prosecuted for failing to surrender, would he be able to rely, in an English court, on diplomatic immunity under the VCDR? Thinking through this question involves a degree of speculation, for we don’t yet know what the Foreign and Commonwealth Office’s (FCO) posture towards any such claim would be. We will assume, however, that the FCO will maintain an approach consistent with its statement (reported here) of 11 January 2018: ‘The government of Ecuador recently requested diplomatic status for Mr Assange here in the UK. The UK did not grant that request, nor are we in talks with Ecuador on this matter.’ In other words, we will assume that the FCO would not recognise Assange as a diplomat.
How the matter would be resolved in domestic English proceedings is a difficult question. It involves consideration of the respective roles of courts and the executive in matters of foreign affairs, the distinction between questions of fact and questions of law in giving effect to FCO certificates, and the potential continued application of the common law principle that the courts and the executive should speak with one voice.
The Diplomatic Privileges Act
As a matter of domestic law, the starting point is the Diplomatic Privileges Act 1964 (DPA), which gives effect to the VCDR. In thinking through how the Assange matter would proceed in a domestic court, Section 4, which sets out the role of the FCO in matters of this kind, is crucial:
‘If in any proceedings any question arises whether or not any person is entitled to any privilege or immunity under this Act a certificate issued by or under the authority of the Secretary of State stating any fact relating to that question shall be conclusive evidence of that fact.’
