They may, but someone would have to be upset enough to go to the bother and expense of doing so. If you are not causing a problem, then I can't see why anyone would want to enforce it. As someone else said, it would have been better if the Piplings had settled this with their neighbours amicably - out of court. I only know what I've read on this site, but I wonder what would have happened had the original planning concent not been given - would Piplings still be running a smaller service from their premises and if so would this have been more acceptible to the neighbours? I dont know..
