There have been many demolitions in Almeria province of properties built on rural land and given building licences by corrupt Mayors. The Almazora Valley has been particularly hard hit and many Brits have lost everything. There is no compensation and the courts are full with claims against the Junta. So far rejected by the courts.
I now that’s a different matter from the thread but it does show the authorities will act quickly against non Spanish owners where other illegal developments with bank interests in them get left alone. Or at least remain in the courts system gathering dust.
Here is an example which has been going on for years. I still don’t believe it will ever be demolished.
