Both in common law and in civil law, a rebuttable presumption (in Latin, praesumptio iuris tantum) is an assumption made by a court, one that is taken to be true unless someone comes forward to contest it and prove otherwise. For example, a defendant in a criminal case is presumed innocent until proved guilty. A rebuttable presumption is often associated with prima facie evidence. (Wikipedia)
