Why does the question of whether something counts as properly "scientific" matter to questions of evidence in criminal law? what are some of the problems with applying criteria that are meant to determine whether something is a science in court cases?

Whether something counts as scientific evidence in criminal law must be taken into careful consideration, since once a proof is established as scientific it becomes an authority argument.
