과학 기술의 발달과 가치관의 다양화에 따라 현대 사회는 점점 전문화되고 복잡해지고 있고, 그에 따라 소송의 내용도 그렇게 변화하고 있다. 법관은 전문 분야에 관한 지식이 부족할 수밖에 없으므로 사건을 올바르게 처리하기 위해서는 전문가의 도움을 받아야 하는데 우리나라는 그 방법으로 감정 제도를 채택하였다. 전문심리위원 제도는 전문가의 지식을 소송에 반영하기 위한 보조적 수단으로 2007년에 도입되었다. 감정 제도에서는 법원이 선정한 전문가인 감정인이 당해 사건에 관하여 전문 지식을 적용한 감정 결과가 독립적인 증거가 된다. 전문 지식이 반영된 감정 결과는 소송의 승패에 결정적인 영향을 미치게 되어 그 중요성은 매우 크다. 전문심리위원은 법관의 보조자로서 소송에 필요한 전문 지식에 관한 설명을 하거나 의견을 제시하는데 그것이 증거가 될 수는 없어도 실질적으로는 중요한 역할을 수행할 수 있다. 이렇게 중요한 감정 제도에 관하여 감정인 선정 및 감정 결과의 적정성, 감정 비용의 적절성의 측면에서 여러 문제점이 지적되어 왔다. 법원은 이를 개선하기 위해 여러 노력을 기울여 왔으나 문제의 심각성은 더욱 커지고 있다. 전문심리위원 제도에 관하여는 활용도가 너무 미약하다는 문제점이 지속적으로 지적되어 왔다. 전문 지식을 소송에 반영하는 수단으로 미국은 전문가 증언 제도를, 독일, 일본, 프랑스는 우리나라와 같은 감정 제도를 각 채택하였는데 위 국가들은 제도와 여건에 맞추어 이를 적절하게 운용하고 있다. 그중 독일, 일본, 프랑스는 전문가 집단과 긴밀한 협력 체계를 갖추고 이를 토대로 감정 제도에 관한 여러 방안을 시행하면서 상당한 성과를 내고 있다. 이 연구에서는 위 국가들의 방안을 참고로 하여 감정 제도에 관하여 제도적 및 운용 실태적인 개선 방안들을 제안하였다. 거기에는 사실심 충실화 사법제도개선위원회가 제안한 전문심리관 제도의 도입을 비롯하여 이미 마련된 개선 방안들이 포함되어 있다. 전문심리위원 제도를 활성화하기 위한 몇 가지 방안도 제안하였다. 무엇보다 강조하고 싶은 것은 제안한 여러 개선 방안이 제대로 운용되기 위해서는 법원과 전문가 집단 사이에 공고한 협력 관계가 수립되어야 한다는 점이다. 이를 위한 지속적이고 조직적인 노력이 선행되어야 한다. The development of science and technology, and the diverse values make modern society become increasingly specialized and complex, and thus the contents of the legal actions change accordingly. Judges who lack expertise in a specific area need experts’ help in order to handle the case properly. So the appraisal system has been adopted in Korea. The expert commissioner system was introduced in 2007 as a supplementary means to reflect the knowledge of experts in the trial proceedings. In the appraisal system, the result of appraisal that the appraiser appointed by the court makes about a case with his expertise, can become an independent evidence. The result of appraisal which reflects expertise is very important because it has a decisive effect on the outcome of litigation. An expert commissioner shall make an explanation or offer an opinion which cannot become an evidence but may play an important role in necessary expertise in litigation as the assistant of a judge. Many problems including the propriety of both an appointed appraiser, the result of appraisal, and the adequacy of appraisal cost on such important appraisal system have been pointed out. The seriousness of these problems gets bigger despite of many efforts by courts. The problem that the frequency of use is too low has been pointed out on the expert commissioner system. In order to reflect expertise in litigation, the United States has adopted the expert witness system, and Germany, Japan as well as France have adopted the appraisal system like that of Korea. These nations operate them properly according to their systems and environments. Germany, Japan and France have been equipped with a close cooperation system with expert groups and have carried out considerable achievements through various measures in the appraisal system accordingly. This research suggests improvement plans in view of both system and operation of the appraisal system. Some of them including the introduction of the ‘Expert Examiner System’ suggested by the ‘Committee on Trial Reform’ have been already proposed. Several plans are suggested in order to boost the expert commissioner system as well. This research emphasizes the most that a firm cooperative relationship between the judiciary and expert groups must be made in order to operate improvement plans this research suggests. For this, continuous and systematic efforts should be preceded.

국내 사법제도 내에서 전문심리위원제도 활용 실태 -심리학 분야 중심으로-

이선근 한국법심리학회 2012 한국심리학회지: 법 Vol.3 No.1

As modern society become more complicated and science are developing, proper and timely dispute resolutions are demanded for specialized litigations such as construction litigation, health care litigation, and intellectual property litigation. Full trial of such litigations are demanded as well. However, it is difficult to have expertise and experience in all area of litigation by judges in reality. For that reason, the court indicates experts for the related area to obtain their specialized knowledge and experience which is called expert commissioner system. In this study, literature research has been performed to understand the influence of professional opinion on sentencing in real criminal cases by judges after introducing psychology area out of expert commissioner system in criminal justice in Korea. First, introduction of expert commissioner system and related official regulation has been studied. In addition similar systems from other countries have been studied and psychological assessment tools have been introduced to explain psychological explanation by expert commissioner system in Korea. Several cases have been reviewed to understand influence of psychological explanation from the cases which expert commissioner system was applied on assessment of cases by judges. As a result, request of psychological explanation by expert commissioner system have been increased during year 2008 when first time the system has been introduced and 2009, but the request has been plunged in year 2010. Even if the cases apply this system, no psychological explanation was recorded for the reason of sentencing by judicial decision. Therefore, it is impossible to detect whether psychological explanation by expert commissioner system has effect on sentencing or not. Consequently, judges still have some freedom of sentencing even if psychological explanation by expert commissioner system has been requested still after expert commissioner system has been introduced to offer objective standard for sentencing by presenting professional knowledge and interpretation. 현대 사회가 복잡해지고 과학기술이 발달함에 따라 건축관계소송, 의료관계소송, 지적재산권관계소송 등 소위 전문소송에 대한 적정하고 신속한 분쟁해결과 충분한 심리에 대한 요구가 높아졌다. 그러나 현실적으로 법관이 소송과 관련된 모든 분야의 전문지식과 경험을 갖추기 어렵기 때문에 법원은 해당 사건의 관련 전문가를 지정하여 관련 사건의 전문적인 학식과 경험을 지원받게 되는 전문심리위원제도가 마련되었다. 본 논문은 현재 국내 형사사건의 재판과정에 도입된 전문심리위원제도 중 심리학 분야에서 피고인에 대한 전문가의 심리적 설명이 실질적 형사사건의 재판과정에서 법관의 양형판단에 영향을 미치는지에 대해 알아보려고 문헌연구를 중심으로 하여 작성되었다. 먼저 전문심리위원제도의 도입과 그와 관련된 법규정을 알아보았다. 또한 외국의 유사제도를 알아보고 우리나라의 전문심리위원제도에서 전문심리위원들이 심리적 설명을 위해 사용하는 심리평가 도구들에 대해 간략히 소개하였다. 이후 전문심리제도를 이용한 사건들에서 전문심리위원의 심리적 설명이 법관의 양형판단에 영향을 미쳤는지를 알아보고자 몇 가지 사례를 살펴보았다. 그 결과, 전문심리위원의 심리적 설명서를 요청한 사례들은 본 제도가 처음 시행된 2008년과 2009년에는 증가 추세였으나 2010년에는 급감하였으며, 본 제도를 이용한 사건들이더라도 판결문의 양형이유에 전문가의 의견서에 대한 내용이 기술되지 않았다. 따라서 법관들이 양형을 판단함에 있어 전문심리위원의 심리적 의견서가 영향을 미쳤는지 아닌지를 판단하는 것이 불가능하다. 결과적으로 법관의 양형판단에 있어 보다 객관적인 기준을 제시하고 전문 지식과 해석을 제공하여 재판의 원활한 진행을 돕고자 마련된 전문심리위원제도는 해당 사건에서 전문가의 의견서를 요청했다 하더라도 이와 상관없이 법관들은 여전히 자유재량권을 사용하고 양형을 판단하고 있다고 생각된다.

특허소송에서 전문심리위원제도의 개선방안에 관한 연구

신혜은 한국지식재산학회 2019 産業財産權 Vol.- No.59

Professional litigations, such as medical malpractice litigation, architectural litigation, and intellectual property litigation, often require highly specialized knowledge to identify issues. In particular, patent litigation is more so. In patent litigation, it is difficult to expect judges having specific and professional insights into all technical areas, therefore, expert assistance is required. Korea has basically supplemented the judge's judgment ability through the appraisal system. However, in order to cope with professional litigation more effectively, the Civil Procedure Act of 2007 was revised and an expert advisor system was introduced. More than 10 years have passed since the introduction of this system, however, it has been pointed out that this system is still not being used properly. The purpose of this study is to improve the expert advisor system in patent litigation. Especially, I tried to propose a method to improve the expert advisor system in the current patent lawsuit by comparative legal study of the system in Japan which became reference of the expert advisor system of Korea. The expert advisor system is a system that has many merits, such as being able to complement the shortcomings of the appraisal system and play a role as a simple appraisal. Nevertheless, the problem is that the utilization is too low. No matter how good a system is, if it can not be used properly, the intention of introducing it will be halved. If an expert advisor system is activated and each of the advantages of the appraisal system and the expert advisor system can be utilized effectively, a faster and more reliable patent litigation will be possible. 이른바 현대형 소송으로 불리는 의료 과실 소송, 건축 관계 소송, 지식재산권 소송 등과 같은 전문 소송은 사안을 파악하기 위해 고도의 전문적 지식이 필요한 경우가 많다. 특히 특허소송은 더욱 그러하다. 사실관계 확정을 위해 기술적인 전문지식을 필요로 하는 경우가많은 특허소송에서 법관에게 모든 기술 분야에 대한 구체적이고 전문적인 식견을 기대하는 것은 어렵고 전문가의 도움이 필요하다. 우리나라는 기본적으로 감정제도를 통해 법관의 판단능력을 보충하여왔지만 전문소송에 보다 효율적으로 대처하기 위해 2007년 민사소송법을 개정하여 전문심리위원제도가 도입되게 되었다. 그런데 전문심리위원제도는 동 제도가 도입된 지 벌써 10년 이상이 흘렀지만 제대로 활용되고 있지 못하다는 문제가 계속해서 지적되고 있다. 본 연구에서는 우리나라 전문심리위원제도의 참고가 된 일본의 전문위원제도를 비교법적으로 연구함으로써 현행 특허소송에서 전문심리위원제도가 가지는 문제점과 한계를 파악하고 이를 개선하기 위한 방안을 제시하고자 하였다. 전문심리위원제도는 감정제도가 가지는 단점을 보완하고 간이 감정으로서의 역할을 담당할 수 있는 등 많은 장점을 가지는 제도이다. 그럼에도 불구하고 활용도가 지나치게 낮다는 점이 문제이다. 아무리 좋은 제도라도 제대로 활용되지 못한다면도입취지가 반감될 수밖에 없다. 동 연구의 제안에 따라 전문심리위원제도가 활성화되고, 감정제도와 전문심리위원 제도가 가지는 각각의 장점을 살려 효율적으로 활용될 수 있다면 보다 신속하고 신뢰성있는 특허소송이 가능할 것으로 생각된다.

As the demand of nuclear power plant equipment is continuously growing worldwide, the importance of handling nuclear strategic materials is also increasing. While the number of cases submitted for the exports of nuclear-power commodity and technology is dramatically increasing, preadjudication (or prescreening to be simple) of strategic materials has been done so far by experts of a long-time experience and extensive field knowledge. However, there is severe shortage of experts in this domain, not to mention that it takes a long time to develop an expert. Because human experts must manually evaluate all the documents submitted for export permission, the current practice of nuclear material export is neither time-efficient nor cost-effective. Toward alleviating the problem of relying on costly human experts only, our research proposes a new system designed to help field experts make their decisions more effectively and efficiently. The proposed system is built upon case-based reasoning, which in essence extracts key features from the existing cases, compares the features with the features of a new case, and derives a solution for the new case by referencing similar cases and their solutions. Our research proposes a framework of case-based reasoning system, designs a case-based reasoning system for the control of nuclear material exports, and evaluates the performance of alternative keyword extraction methods (full automatic, full manual, and semi-automatic). A keyword extraction method is an essential component of the case-based reasoning system as it is used to extract key features of the cases. The full automatic method was conducted using TF-IDF, which is a widely used de facto standard method for representative keyword extraction in text mining. TF (Term Frequency) is based on the frequency count of the term within a document, showing how important the term is within a document while IDF (Inverted Document Frequency) is based on the infrequency of the term within a document set, showing how uniquely the term represents the document. The results show that the semi-automatic approach, which is based on the collaboration of machine and human, is the most effective solution regardless of whether the human is a field expert or a student who majors in nuclear engineering. Moreover, we propose a new approach of computing nuclear document similarity along with a new framework of document analysis. The proposed algorithm of nuclear document similarity considers both documentto-document similarity (α) and document-to-nuclear system similarity (β), in order to derive the final score (γ) for the decision of whether the presented case is of strategic material or not. The final score (γ) represents a document similarity between the past cases and the new case. The score is induced by not only exploiting conventional TF-IDF, but utilizing a nuclear system similarity score, which takes the context of nuclear system domain into account. Finally, the system retrieves top-3 documents stored in the case base that are considered as the most similar cases with regard to the new case, and provides them with the degree of credibility. With this final score and the credibility score, it becomes easier for a user to see which documents in the case base are more worthy of looking up so that the user can make a proper decision with relatively lower cost. The evaluation of the system has been conducted by developing a prototype and testing with field data. The system workflows and outcomes have been verified by the field experts. This research is expected to contribute the growth of knowledge service industry by proposing a new system that can effectively reduce the burden of relying on costly human experts for the export control of nuclear materials and that can be considered as a meaningful example of knowledge service application.
