It's highly partial, and it says nothing about the opposition not allowed to talk. It does say that there was a bitter debate, though, and that it was interrupted twice. It only quotes members from parties against the referendum.
And we have interruptions in every other session of both the Spanish and Catalan Parliaments, from all political spectrum. That's what makes Spanish politics so amusing.
I have to say though that it'll be hard to find a partial accounting of the story, given the state of Spanish media.
