So-called Wang-jaesan decision (2013do2511) was declared by ‘Korean Supreme Court’ (hereafter ‘KSC’) in July, 2013. The decision had a lot of important substantial and procedural issues in criminal spheres. However, what I have tried to concentrate in this review are only two issues, the one is the issue of the authenticity of electronic evidence (or digital evidence), the other is the issue of the application of ‘the Korean version hearsay rule’ (hereafter ‘KHR’) of the electronic evidence. The methodology of this review is the comparative analysis of the Wang-jaesan decision from the perspective of Federal Rules of Evidence (hereafter ‘FRE’). In Wang-jaesan decision KSC defined the concept of integrity of electronic evidence as ‘the contents of the digital data have not been altered in any manner from the moment that were seized’ or ‘that evidence wasn’t changed after it was captured or collected.’ The meaning of this concept is different from the meaning of the traditional ‘exactness of utterances’(成立의 眞正) of article 312, 312 of KHR. That concept was made from the unique Korean modern legal history. However, it cannot deal with so many hard cases properly. Therefore I suggest in chapter Ⅰ, Ⅱ, Ⅲ, Ⅳ that We Korean legal scholars and practitioners should adopt the concept of authentication something like FRE, even though Korean Criminal Procedure Law does not have clear stipulations about it. In chapter Ⅴ, Ⅵ I did comparing analyses about the applications of KHR by KSC since 1990’s up to the 2010’s. I found that KSC has adopted enormously FRE when there were no clear stipulations in Korean Criminal Procedure Law. This is a kind of interesting phenomenon which deserves to be analyzed from the perspective of comparative law and global legal transplant of evidence rule.

Introducing hearsay rule in 1961, the words of provisions that provide the authentication and attendance of the declarant as exceptions of principle of the court's self-experience, were used as exceptions of the hearsay rule. It results in confusion of the elements of the hearsay rule with the elements of the authentication in the jurisprudence. Many literatures insist and place emphasis on the elements of the authentication as the elements of exceptions of the hearsay rule. With this confusion and misunderstanding, it became very difficult to understand the hearsay rule and many improper interpretations result from this confusion. In the future, the discussion which distinguish the elements of the hearsay rule from the elements of the authentication should be made actively and lead the academy and practice.

According to the development of computer, many people recently record their statements with computer. Therefore new issue about the admissibility of the statements recorded in computer file floats on the legal horizon. From the viewpoint of the anglo-american hearsay rule, this issue could be easily cleared by the rule and exception. In principle, hearsay rule say that out of court statements be inadmissible for the evidence of the truthfulness of the contents of the statements and call this out of court statements hearsay. Hearsay rule focuses on the statements, not the method by which this statements are recorded or transferred. As the result, the out of court statements recorded in computer file are hearsay when they are given as evidence for the truthfulness of the contents of the statements But hearsay rule know many exceptions which make the out of court statements admissible. At first, hearsay statements by the defendant are admissible as a exception of hearsay rule. Secondly, hearsay statements by the third party are admissible when there is necessity and guarantee of trustworthiness. There are many categories and general exceptions which represent this necessity and guarantee of trustworthiness. On the other hand, there is another point for the admissibility of the evidence. It is the authentication. Authentication can be given by many methods, as example, by testimony of the declarant, by the testimony of the third party who knows the evidence or other objective materials. From this point of view, we can consider § 313① and § 315 possible clauses for the admissibility of private statements in computer file. At first, § 313① require the authentication be made by the declarant's oral testimony. The Court says that this testimony is the one in which the declarant admit the statements to be made by himself. According to the explanation, the admissibility is decided only by the declarant's subjective admission. This result is unreasonable because the issue of admissibility should be decided by the objective facts. Therefore the testimony of the declarant in § 313① should be construed as all the statements in court and the authentication be decided by all the statements of the declarant in court objectively considered with other facts and materials. And § 315. 3. provides general clause of guarantee of trustworthiness as exception of hearsay rule. This guarantee of trustworthiness as a condition for admissibility is relatively lower level of reliability than the reliability for the selection from the admissible evidences for trusting the facts asserted. The selection from the admissible evidences is for the fact finder, for example, trial jury. not for the leader of the procedure. But in the Court' decision, the Court seems to be unable to distinguish this guarantee of trustworthiness as a condition for admissibility from the issue of selection from the admissible evidences for trusting the facts asserted. So the Court's decision is inappropriate and the statements recorded in computer file should have been admitted.

Recently, many people live or travel abroad by various reasons. In this global era, we cannot only require the witness to come to homeland for testifying in court. It is necessary to provide a new method to take a reliable evidence which can solve the case with the witness staying abroad. In this case, the Prosecutor's Office try to give a new method by requesting the Consul in Japan to hear the witness and record the statements. According to the Vienna Convention on Consular Relations, Consul can hear the people of the Consul's nation. German Consular Relations Law provides that the admissibility of out of court statements recorded by Consul is regulated according to the institution which makes the request. Therefore, if the request comes from court, the statements recorded by the Consul according to the request are treated as statements recorded by Judge. From this point of view, the Prosecutor's Office insisted that the out of court statements recorded by Consul in Japanese be treated as the out of court statements recorded by Judge in deciding the guarantee of trustworthiness. But the Court construed that the statements recorded by Consul as the statements recorded by private person. Worse than this, the Court denies the guarantee of trustworthiness as the condition for the admissibility for the evidence. But this guarantee of trustworthiness as a condition for admissibility is relatively lower level of reliability than the reliability for the selection from the admissible evidences for trusting the facts asserted. The selection from the admissible evidences is for the fact finder, for example, trial jury. not for the leader of the procedure. But in this case, the Court seems to be unable to distinguish this guarantee of trustworthiness as a condition for admissibility from the issue of selection from the admissible evidences for trusting the facts asserted. So the Court's decision is inappropriate and the statements recorded by Consul should have been admitted.
