Legal fiction

A legal fiction is a fact assumed or created by courts,[1] which is then used in order to help reach a decision or to apply a legal rule. The concept is used almost exclusively in common law jurisdictions, particularly in England. An example of a legal fiction outside common law is that it is legally possible to have consumed an illegal substance without having owned it. This means that owning or handling cannabis is illegal in some jurisdictions, while testing positive for cannabis consumption is not illegal.
