It's absolutely legitimate to be upset. However, identifying a lawfare trick in a close vote to a dictatorship is serious hyperbole. I'm afraid that's counterproductive.
My point is that this was a minority of 46.7% making that decision (because of a technicality that has been pointed out already). In a dictatorship, a minority of 1 against a million or more makes all the decisions. Even though you can say 46.7% and 0.0001% are both below 50%, it's missing a lot of nuance to claim they are of the same nature.
They passed a regulation with 276 votes in favor, 314 votes against, and 17 abstained. The minority decided instead of the majority.
If this is not a dictatorship, what is it then? In any case, it has nothing to do with the democracy.
