There's a quote in there:
For instance, it is not possible to interrupt a speaker at will, something that's common in many national parliaments.
Where? At least here in Spain, you can't interrupt the speaker when they have the floor. Doing otherwise seems like a recipe for disaster.
Now that you mention that, I seem to recall something similar does already exist in the EU Parliament. Blue Cards, which I think every MEP has a few of.
From the first article (which I admit I just skimmed the top of it):
Could be interesting to see how that turns out.
