Looks like the owner didn’t do this gracefully and didn’t care much about the significance of the Art to its creators and others who appreciated it likely way more than he did. That’s not very nice. On the other hand, if it is indeed his property he should have the right to do what he wants with it. Unless there was a contract of some kind, not a lawyer, I don’t understand how the judge could have sided with the artists who themselves were on a private property and ended up making claims to said property. Aren’t judges supposed to be impartial and make decisions based on the letter of the law ? Though I suppose the law in the us may protect the artists in this case.
