Not a good position to be in QZ - but there is a difference between people flouting legislation (which everyone does at some point in some manner) and causing trouble - noisy neigbours are no fun If it's short term I think you will just have to make do for the night If it is potentially longer-term then I would agree with ruffers - start a log of activity. You mention "in the past" - is this an ongoing thing, something that happens regularly, or just once in a blue moon?
