A system of circumstantial evidence for fact-finding in criminal trial

Abstract One of the most intractable, but significant problems in the theory of legal evidence concerns circumstantial evidence. The diversity and complexity of criminal cases cause some bottlenecks and difficulties in developing reasonable methods to prove the criminal issue by means of circumstantial evidence. The main purpose of this paper is to present more effective methods of fact-finding just by means of a system of circumstantial evidence (SCE). On the basis of analysis of the nature of circumstantial evidence, we find it necessary for the prosecution to construct a SCE in order to make a judge or jury accept the prosecution’s conclusion as the best explanation. We also present a reasonable logical structure of such a system and address some legal and logical problems in introducing it.
