What still amazes me is that the EU, which has no formal Constitution, is telling the Poles to essentially jettison their Constitution.
The EU states that they have a Constitutional Charter (Lisbon Treaty), which is sort of, maybe, kind of, could be equivalent to a formal Constitution, but maybe, sort of, kind of, not.
The EU has tried to craft a formal Constitution, but each time they've tried the process has collapsed under its own weight.
The US Constitution is what, 4 hand written pages?
Last draft of the European Constitution was, IIRC, something like 3,900 pages long and it still wasn't considered to be complete.
The Treaty of Lisbon, however, took care of any further attempts at a full Constitution by formally rejecting one.
