Qui Tam Action
A rule of law which permits a court to assume a fact is true until such time as there is a preponderance (greater weight) of evidence which disproves or outweighs (rebuts) the presumption. each presumption is based upon a particular set of apparent facts paired with established laws, logic, reasoning or individual rights. a presumption is rebuttable in that it can be refuted by factual evidence. one can present facts to persuade the judge that the presumption is not true. examples: a child born of a husband and wife living together is presumed to be the natural child of the husband unless there is conclusive proof it is not; a person who has disappeared and not been heard from for seven years is presumed to be dead, but the presumption could be rebutted if he/she is found alive; an accused person is presumed innocent until proven guilty. these are sometimes called rebuttable presumptions to distinguish them from absolute, conclusive or irrebuttable presumptions in which rules of law and logic dictate that there is no possible way the presumption can be disproved. however, if a fact is absolute it is not truly a presumption at all, but a certainty.
