Principle: A man must not make such use of his property as unreasonably and unnecessarily to cause inconvenience to his neighbors.Fact: Mr. Z is the owner of a plot measuring 50 feet by 80 feet. He constructed a small house at one corner and was using the rest of the land as a cow shed. He had 20 cows and is involved in selling milk to the public. The cow dung and other wastes were openly stored in a small 10 feet by 8 feet tank. This constantly paved the way for bad smell and breeding of mosquitoes. Mrs. Y, his neighbor, constantly complained to X, but in vain.
