Common questions
Does a reverse-burden presumption shift the ultimate burden of proof to the accused?+
It shifts an evidential burden on the accused to produce evidence raising reasonable doubt on the presumed element, but the prosecution typically still bears the ultimate legal burden of proving guilt beyond reasonable doubt on the case overall.
Have reverse-burden presumptions faced constitutional challenge?+
Yes, courts in multiple jurisdictions have reviewed such presumptions against fair trial and presumption-of-innocence guarantees, generally upholding them where the presumption is rationally connected to the basic fact and the accused retains a genuine opportunity to rebut it.
Why are threshold quantities used to trigger the presumption in drug cases?+
A quantity threshold gives the prosecution an objective, easily proven basic fact, since the amount seized is a matter of weighing and testing rather than requiring direct proof of the accused's intent, which is normally the hardest element to establish.
