Legal Principle: When anyone uses his property in such a manner as to cause damage to others, he commits the wrongful act of private nuisance.Factual Situation: X and Y are the owners of adjoining flats. X leased his flat to R an AIDS patient and activist. Fearing the spread of the disease, Y's tenant vacated his flat, and since then no tenant was ready to move in Y's flat. Y repeatedly requested X to change his tenant, but to no use. Now Y has filed a suit against X for causing private nuisance. (P.U. OCET 2012)
