A few months ago, the Assemblea held a vote for its members to decide whether or not to press the pro-independence parties to support a binding referendum on Catalan independence. The idea seems to have come from the CUP and is now embraced by all three pro-independence parties, as well as the Assemblea and other grassroots groups.
[This is an interesting move in my dance with the ANC because 18 months ago or so, I had an argument with ANC people in the street in Cerdanyola who at the time were calling for a unilateral declaration of independence, which I insisted would never be recognized internationally – I said that we needed a binding referendum; now, I'm a member of the ANC and opposed to the referendum. One of us is out of step, almost certainly me].
Catalan government spokesperson Neus Munté today outlined the importance of a referendum being "binding and meeting international standards" in order for it to be recognized in other countries. She also said that people on both sides of the debate must turn out and vote [i.e., 'remain' supporters can't be seen to stay at home like they did on #9N], and that in order to achieve this, the referendum must have concrete "legal and political consequences".
In case you hadn't noticed, these are exactly the arguments used by those of us unsure about the workability of the new plan. It's obvious that a binding referendum with a high turnout would be the best and most democratic way to deliver independence, were that the result. But simply saying that a referendum needs to be binding, and have a large turnout, and have legal and political consequences, is almost totally useless. We need to know how they're going to make this happen.
In Spain's current political climate, the chances of the next government (my money is on a minority PP government) agreeing to a binding referendum are minimal. So all the PSC, Cs and PP need to do to make this proposed referendum another #9N is convince their supporters not to bother voting. Apart from the problem with drawing up an electoral register, there is the issue of ensuring legal consequences from a referendum the Spanish government will certainly declare to be illegal.
It might be that I'm not seeing the plan. It might be that Munté et al have a plan and they're just preparing the ground. Maybe they're hoping for a repeat of #27S, when they called the elections a plebiscite and the PP eventually agreed. But for the moment, this binding referendum is a conundrum: no one opposed will vote unless the referendum is taken seriously, and the referendum won't be taken seriously unless the opposition votes.
