3) Lawrence owns a bungalow. His next door neighbours have a two-storey house. Every few days, his neighbours sweep their second-floor balcony causing dust, dirt, cigarette butts, and bottle caps to fall onto Lawrence's deck. Lawrence has tried to tell them not to sweep them onto his deck, but the neighbours continue to do so. Question: a) What tort have the neighbours possibly committed? b) Has that tort been committed? Explain why or why not. (List the elements of the relevant tort and explain why those elements are or are not satisfied)
