Common law privilege

This is for circumstances where there is legal protection to defamatory statements that are untrue for the common convenience and welfare of society. For example this is used  when a defamatory statement is made by someone undertaking their legal, moral or social duty to a person who has a corresponding duty or interest in receiving it. Common law protection also stretches to anyone making a defamatory statement in reply to an attack on his/her character. There is also qualified protection for fair and accurate reports of judicial proceedings in the UK and reports on the British parliament.
