디지털 기술의 발전에 따라 여러 방식의 무인 감시카메라가 상용화되었지만 기술상의 한계로 식별에 하자가 있는 디지털 증거들이 많은 것이 현실이다. 이러한 증거에 저해상도 사진의 식별력을 높여주는 초해상도 기술을 적용하면 증거의 가용범위를 확장할 수 있다. 초해상도 기술의 정확도가 일정 수준 이상으로 보장되기 시작한 지 얼마 되지 않은 관계로 해당 기술의 결과물에 증거능력을 인정할 수 있을지 여부에 대한 논의가 전무하다. 이 기술의 결과물은 현장의 정보를 그대로 담고 있는 것은 아닌바, 일반적인 증거능력 요건의 만족만으로 증거능력이 긍정되기는 어려울 것이다. 그러나 초해상도 기계학습 전문가가 작성한 검사기록 보고서라는 진술증거로서 증거능력이 인정될 여지가 있다. 이러한 방식으로 증거능력을 인정받기 위해서는 증거능력의 기본 요건인 적법성과 임의성이 갖추어져야 한다. 그리고 여타 전 문증거와 마찬가지로 진술에 대해 전문법칙의 예외의 요건인 필요성과 신뢰성까지 인정되는 경우 에 한하여 증거능력이 긍정될 수 있다. 전문법칙의 예외의 요건 중 신뢰성까지 전문가와 기술 양자에 대하여 요구될 것이다. 본지에서는 기술에 대한 신뢰성을 갖추기 위한 구체적인 기준을 기술적인 관점에서 제시한다.

The defendant consulted an attorney-at-law regarding legal issues which might constitute crimes before commencement of an investigation. The defendant received legal opinion from the counsel by e-mail, which was later seized and presented as evidence of guilt by investigative authority.The court of original instance rejected to accept written legal opinion from the counsel as evidence on the ground of Attorney-Client Privilege. The Supreme Court, however, deemed Attorney-Client Privilege is not rooted in our legal system.I concur with the opinion of the Supreme Court in that we have yet to find traditional or provisional basis for Attorney-Client Privilege. It is premature to acknowledge the concept of Attorney-Client Privilege without in-depth probe. Instead, the majority opinion of the Supreme Court looked to Articles 314 and 149 of the Criminal Procedure Act. Article 314 provides one of the exceptions to hearsay rule, which allows the written statement to be admitted as evidence of guilt without cross-examination against the person who wrote the statement, in case that the person is not available due to illness, unknown whereabouts, etc. as well as that the statement is proved to have been written under especially reliable circumstances. Article 149 confers the right to refuse to testify on the legal counsel regarding professional secrets he obtained in the course of business. The majority opinion of the Supreme Court ruled that Article 314 shall not apply in case that the legal counsel exercises his right to refuse to testify under Article 149. The majority opinion based its rationale on the fact that Article 314 had been revised with a tendency to reinforce oral hearing and direct examination by narrowing the scope of the exceptions to hearsay rule, as well as on the purpose Article 149 seeks to achieve. On the contrary, the dissenting opinion of the Supreme Court deemed that Article 314 shall apply in case of exercise of right for refusal of witness under Article 149. The dissenting opinion pointed out that Article 314 serves to discover the truth by allowing hearsay evidence under exceptional circumstances. According to the dissenting opinion, there is no difference between situation where the witness is unable to appear because of illness, etc. and situation where the witness exercises his right to refuse to testify when it comes to applying Article 314.I concur with the majority opinion of the Supreme Court. The witness who refuses to testify may or may not have lawful grounds to refuse. If he has sufficient lawful grounds, we should pay attention to the purpose of the Article which confers the right to refuse to testify. In this context, it stands to reason to declare that Article 314 shall not apply in case that the legal counsel exercises his right to refuse to testify under Article 149. By denying the admissibility of legal opinion as evidence of guilt, written by the legal counsel who lawfully exercises the right to refuse to testify, we can further the right to refuse to testify as well as the principle of oral hearing and direct examination.

It is defined that digital evidence is all valuable information as evidence that is preserved and delivered in digital form, the salient traits of its character is independent from a storage, invisible, unreadable etc., it must be solved authenticity, reliability, best evidence for the purpose of its admissibility.In our criminal procedure law, the evidence is classified into two types, statements and objects, objects as evidence are composed of documents and things, it could be included statements by a person or not in documents as evidence. In essence digital evidence is regarded as documents evidence so hearsay-rule is applicable to it.To acquire admissibility of digital evidence made by a person it is important that the person acknowledges his digitals documents produced by him-self according to the criminal procedure law art. 313① in a court but the opinion that only the acknowledgement by a writer can give admissibility of digital evidence is very dangerous in criminal procedure because it may make valuable evidences useless things.In the revised criminal procedure law new solution is imposed in it. Even though a person deny its contents in a report said by him-self for example “I didn’t talk like that in a report”, prosecutor could prove that a report made by a investigator is credible and exact in the objective way including recording video-tape etc., the admissibility of a report evidence can be achieved recognition.This revised purpose must be regraded as a new basis in evidence law totally, even if a person deny his digital document made by him-self for example “I didn't make digital document like that”, prosecutor could prove that a digital document is made by him-self in the objective way including analysis meta-data etc., “it is you who made this digital document”, the admissibility of a digital document evidence could be achieved recognition. if to prove who made a digital document evidence end in failure, its admissibility have to be reviewed again according to criminal procedure law art. 315, valuable digital evidence must not go into the dumper easily.Anyone talking about evidence in criminal procedure cannot help but mention digital information that is essential in it by progress of scientific technology.Much to our regret, there is not at all rule for the purpose of admissibility of digital evidence in present criminal procedure law, as a result many opinions and judicial decisions consider requisites of admissibility of digital document as one of admissibility of non-digital document but an intrinsic attribute of digital evidence is profoundly different from one of traditional evidence.Ultimately I think that criminal procedure law must be revised referring to foreign country’ law to acquire admissibility of digital evidence although a person deny a digital document that is made by him-self, if prosecutor could be successful in pr○○f, “it is written by him-self”, in other words witness or suspect, the digital evidence shall be useful.I wish to be collected g○○d thoughts to prevent that valuable digital evidence may be discharged by only one statement of a wicked-person.

형사재판에서 피고인이 제출한 증거에 대한 증거능력과 증거조사에 관한 연구이다. 국민 참여재판의 출범 및 개정 형사소송법의 시행에 따라 피고인이 제출하는 증거의 중요성이 증대되고 있다. 형사재판에서 공소 제기된 범죄사실에 대한 입증책임은 어디까지나 검사에게 있다. 따라서 피고인이 제출하는 증거는 알리바이 등 공소 범죄사실에 반대되는 사실을 입증하기 위한 증거이든, 공소 범죄사실에 대한 진술증거의 신빙성을 탄핵하기 위한 탄핵증거이든, 모두 그 성질은 탄핵증거라고 보는 것이 합당하다. 그러므로 원칙적으로 증거능력을 필요로 하지 아니하고 탄핵증거로서 증거조사를 하면 족하다. 연구 대상 판례는 이러한 판단을 전제로 하고 있다.
