In the US, I can’t imagine this working. The judge would get a bailiff or cops to haul the demonstrators out. But it serves to highlight an interesting issue. The Greek government is resorting to increasingly draconian measures to collect taxes (attaching them to electricity bill, so you lose your power if you can’t or don’t pay). But a variant has been successful in Iceland. Here, the “Home Defense Team” sought to bar an eviction. And even though it looks like they lost (you can see the police removing the protestors one by one), they allowed the homeowner to remain for a few weeks while a government agency looked into the validity of the debts asserted by the bank.
