No, the decision is very democratic. Sometimes democracy just sucks.
The decision is left up to the elected representatives of the local governments. That's democratic. We can get our state governments to pass laws to limit the practice. That's also democratic.
The court might have ruled that these takings were prohibited, which may have been the right decision, but it wouldn't have been a democratic one.
'Anti-democratic' is a socialist code word for anything that's not socialist.
Democracy is three wolves and a sheep voting on what's for dinner. That's why we used to have a Constitution to protect the sheep. That was before it was used as toilet paper.
