Hi sirjamesp
The document to which you have linked is a collection of papers from an academic forum reflecting upon European identity. There are fifteen papers by different authors, one of whom is an official of the EU and one of whom is a Swedish government official. The phrase “membership of a body politic” occurs once, in a paper by an Italian academic on “European Identity and Citizenship”. It is not used in a context which suggests that it is an attempt to describe the European Citizenship explicitly created by the EU Treaties. And, in any event, the very first page of the document states explicitly that “the contents of this publication do not necessarily reflect the opinion or position of the European Commission.” So it is careless (or worse) of you to present this as the views of “the EU itself”.
I take your point that citizenship can have more than one meaning, and it may or may not mean the same thing as nationality. In a legal context the terms are usually interchangeable; US citizen = US national. But in other contexts the terms are not interchangeable; I consider myself a citizen of Dublin, for example, but there is no such thing as Dublin nationality.
I’m a citizen of Dublin because my home is there, but that gives me no particular legal rights or obligations. I do not think that the word “citizen” is used in this sense in the EU treaties, because (a) there are many people who reside within the EU but are not citizens of the Union, (b) there are many citizens of the Union who do not reside there, and © being a citizen of the Union does carry important legal rights and responsibilities. I think the parallel with the use of the term “citizen” with respect to both the cantons of Switzerland and the Swiss Confederation is a closer one.
You say “you do not have European Union Nationality”, but I wonder is this entirely correct? It’s true, obviously, in the cultural sense; there are many nations in the EU, not one, so membership of the EU population is not, as such, membership of any particular nation. (The same would have been true of the old Soviet Union.) But in the legal sense, where nationality = citizenship = a legal relationship with a political entity which comparable political entities will respect and recognise, I think there is an EU nationality. If I find myself in difficulties in (say) Chile and, in the absence of an Irish embassy, I seek the diplomatic or consular asssistance of officials of another EU member state, the Chilean government will respect this, and will afford to those officials the same access to me as they would afford to Irish officials. Were I to seek assistance from (say) the Australain representatives, it would not be forthcoming but, more to the point, the Chilean authorities could (and almost certainly would) decline to allow the Australian representatives to have access to me. Hence my rights as an EU citizen are recognised not only by my country, by the EU and by other EU member states, but in the international community.
EU nationality in the legal sense therefore exists, although I would concede that it is not as important (or, outside the EU) as useful to me as Irish nationality.
