I’m mainly talking about:
- Voting (at federal elections)
- Jury Duty (at a courtroom)
I know that in certain countries like Australia for example: citizens there actually have to vote otherwise they face a A$20 (12€) fine for literally not putting a vote. There was a case where a guy was sued and received a A$303 (182€) fine on top of that for disregarding the previous penalities. To me, that sounds stupid, voting shouldn’t be “forced” down on citizens, if that’s the right way to say it.
What about the scenario you receive a letter from the courts that you’re selected as a juror? Let’s say you got a letter saying that you’ve been chosen within a pool and assigned a number (like a draft lottery) whether the courts decide if you’re “fit” enough to be a juror at a trial. The thing is, has this happened to you or anyone you know in your country? If so, what is it like receiving a summons?


Of course there is something like EU citizenship. Read the TEU and TFEU. It is conferring its own set of rights but is dependent on someone being a citizen of an EU member state. Hovever there are cases were people who are the one aren’t the other.
There is no state of EU therefore there is no citizenship. You just have the citizenship of a member state.
You did not say before, that EU citizenship is no national citizenship (which it isn’t indeed), you said that EU citizenship does not exist, which is demonstratively false.
Article 20 TFEU
"1. Citizenship of the Union is hereby established. Every person holding the nationality of a Member State shall be a citizen of the Union. Citizenship of the Union shall be additional to and not replace national citizenship.
(a) the right to move and reside freely within the territory of the Member States;
(b) the right to vote and to stand as candidates in elections to the European Parliament and in municipal elections in their Member State of residence, under the same conditions as nationals of that State;
(c ) the right to enjoy, in the territory of a third country in which the Member State of which they are nationals is not represented, the protection of the diplomatic and consular authorities of any Member State on the same conditions as the nationals of that State;
(d) the right to petition the European Parliament, to apply to the European Ombudsman, and to address the institutions and advisory bodies of the Union in any of the Treaty languages and to obtain a reply in the same language.
These rights shall be exercised in accordance with the conditions and limits defined by the Treaties and by the measures adopted thereunder."
