A few days ago I made a prediction about the Catalan President who went to Brussels to avoid the backlash of the Spanish government.
It was clear that he thought the EU was a bastion of democracy and would champion his cause. My prediction was that
1. The EU would treat him like a pariah and ignore him
2. He would refuse to go back to Spain when the courts called him and he would call on the EU to back him
3. Spain, once he did not appear in court, would raise an EU arrest warrant
4. The ex president would be arrested and transported back to Spain
So far 1,2 and 3 have unfolded. I'm waiting for #4. These EU arrest warrants are now a known quantity and are followed up very promptly. So there is virtually no chance of avoiding one and as EU state law is inferior to EU law in this issue, no state court can block it. The only way to block an EU arrest warrant is to get the EU court to void it and there is no way that will happen before he's back in Spain and in a jail cell.
Spain is determined to slam these guys away for the rest of their natural lives so that this never happens again. It is clear they never learn. If they want a slow burn civil war this is exactly the way to go about it.
But the greatest message, for me, is that the EU is not Synonymous with Democracy. Something that the majority of people in many EU states believe it is. Sadly most of the people in the other states will not be following this news so they will not understand what is going on.
If I were on his team I would have told him to get his backside to New York and petition the UN. That would have moved him outside of the EU and the EU arrest warrant. What he did is not extraditable from the US either. Instead he put him right in the firing line of an EU arrest warrant and petitioned a group who have no interest in having a Catalan state within the EU, separate from Spain. Any more than it wanted to deal with Scotland as a separate state in the EU.
