A wise judge

Once a golden necklace was lost from a rich man's house. A few servants worked in that house. Naturally it was suspected that any one of the servants had stolen the necklace. 

The master of the house lodged a complaint before the Judge. All of them were summoned to the court. But all of the servants denied the charge. Then the Judge hit upon a plan. He gave each of them a stick of same length and told them to submit them to the court the following day. 

He told them that the person who had stolen the necklace, his stick would increase an inch. When they returned home, they kept their sticks as they were. But the servant who stole the stick shortened it by an inch. The next day when everybody submitted the sticks, it was found that one stick was short by an inch. Then the thief was detected and he was given punishment.
