The qualified privilege is the privilege of the publisher to publish the matter which is in the interest of public. If someone moves to the court for the loss occurred to him due to some matter published in a newspaper or in other publication, the court will see if the matter published is in the interest of public or not . If the court finds that the matter is in the interest of the public, then the court will dismiss the case. Otherwise the loss of the person who filed the case is to be made good by the publisher.
