The ruling cannot be appealed against.
The Algarrobico hotel, you will remember, is the concrete monstrosity built within the confines of the Cabo de Gata natural park on the way to Carboneras. It is 21 stories high (built against a sloping hill) and the first 14 stories are within the coastal protection area, so these are the ones which must be removed.
All other legal processes currently underway against the hotel must now take into account the fact that half the hotel is illegal, so hopefully the rest of it will also be demolished at some point the future.
The sentence does not stipulate who is responsible for demolishing the hotel, but gives the Environmental Ministry to right to proceed with the destruction.
