What article of the Constitution was Vaitkus talking about?

I watched this:

Job interview with Daiva Žeimyte-Biliene: guest – presidential candidate Eduardas Vaitkus (youtube.com)

There was a moment when Bilienė was trying to find an article according to which we have not joined the EU. Asked Vaitkaus to tell which article exactly. That’s what he was doing there, and at the end he blurted out that he was not her helper lol Anyway, the article must state that 70% of the people with the right to vote should have agreed. One way or another, I’m trying to find that article, but I can’t find it.

CONSTITUTION OF THE REPUBLIC OF LITHUANIA (lrs.lt)

Isn’t this suka just lying about such a thing? Most of the time, these degenerates lie, but they lie in such a way that you can’t check anything, they talk abstractly and that’s all 😀
