This seems an extraordinary decision. Are the Piplings owners planning an appeal? From what I've researched online, there is a right of appeal to the Lands Tribunal if you can show that a restrictive covenant confers no "practical benefit of substantial value". Surely a case for that here? What legal advice / representation have the owners had?

Our house in the area includes a restrictive covenant saying we won't sell it for more than £350. I think we can probably all agree this is now somewhat out-of-date...
