반 공유지 이론은 국제공법의 연구를 위한 새로운 접근법을 제시할 수 있다. 본고는 반 공유지의 구조가 국제공법의 법률 규칙 및 국제법률 기관 그리고 국제 환경법과 같은 다양한 관련 법률 영역에 유효하게 자리 할 수 있음을 알리고자 한다. 또한 기존의 반 공유지 연구를 개관하고 반 공유지 구조에서 오는 문제에 이미 연구된 잠재적 해결책들을 제시한다. 따라서 법률 연구가들이 국제공법의 반 공유지에 관하여 고찰 하는 데 있어 직면 할 수 있는 낯선 간극을 대폭 줄이고자 한다. ‘반 공유지의 비극’이라 알려진 이론은 ‘공유지의 비극’에 대해 대칭적으로 반영된 개념인데 두 모델 모두 공적 자원의 극적 소유, 비 소유 및 협업하여 이룬 결과물에 대한 극단적인 소유와 비 소유라는 배타적인 권리에서 작동하며 서로 작동방식은 다르지만 결과적으로는 둘 다 복리 및 혜택을 축소시킨다. 법적인 반 공유지라는 개념은 공공자원이나 협업의 결과물이 법률 서비스, 법적인 권리 또는 법적 절차에 반영될 때 그 역할을 한다. 또한 보완적이거나 경쟁력 있는 규제 절차가 반영된 반 공유지 개념을 확립할 수 있다. 법적 공유지와 규제된 반 공유지라는 두 개념 모두 국제공법상에 자리하고 있음은 자명하다. 규칙 집합 및 국제공법의 법적 기관에 반 공유지 이론이 존재하므로 정책 결정가들은 그러한 반 공유지를 적용하고 특징지음으로서 어떤 문제점이 생기면 그것을 식별하고 국재공법상에 불필요한 난점들을 피해가며 더 나아가서 개선하는 결과를 가져올 수 있다.

The recent fentanyl dispute between China and the US adds the academic value to the efforts to examine the respective legal regime of public international law and the WTO law on narcotics trafficking. On the one hand, public international law offers a comprehensive framework to address narcotics trafficking but as demonstrated by Chinese proofs, its function is undermined by weak enforcement. On the other hand, there exist some useful mechanisms in the WTO law to combat narcotics trafficking but their weaknesses can also be easily spotted. More importantly, the alarm of the global threat of illicit trade is ringing, which requires our raising awareness to it. Recently, the UNCTAD and the OECD have already taken the initiative to discuss the collective actions, by means of conferences or reports, to deal with illicit trade. In the long run, it will be indispensable to establish an operational governance framework on the international level to effectively curb illicit trade.

The Chinese toxic milk scandal raised tremendous global concerns about food safety in China. To repair the tarnished reputation of domestic food production, Chinese authorities focused on compulsory food safety liability insurance. Unfortunately, the introduction of compulsory food safety liability insurance in the Food Safety Law of the PRC has been delayed by the disagreements of Chinese legal scholars. Chinese legal scholars have examined the legitimacy of compulsory food safety liability insurance in China mainly from the standpoint of domestic laws. The valuable insight of international laws has been ignored by them. This article attempts to fill this research gap by scrutinizing the Chinese endeavor of launching compulsory food safety liability insurance through the joint perspective of public and private international law. It further demonstrates that the ideology of human rights of public international law has already penetrated into the body of broadly-interpreted private international law.

The recent surge of multijurisdictional IP disputes and increase in non-binding soft laws have made scholars cast doubt on the sustainability of public international law and the validity of the current IP legal system. Private lawyers may now think that they do not have to pay keen attention to public international law any longer when providing legal advice to their clients, particularly MNCs. This study makes a concise description of today’s legal environment in the field of IP, focusing on the emerging legal norms of transnational law, particularly in the context of its interplay with public international law. With respect to this, the ongoing and even heightened roles of public international law will be discussed. Finally, a typology is suggested using exponents to express intensity of State sovereignty to facilitate understanding on the relationship between public international law and other categories of law.

IP litigations over mobile digital devices are soaring in many jurisdictions. Based on the observation that the same or closely related infringement claims over the IP rights embedded in a single digital product have been raised in multiple jurisdictions, some literature and legislative proposals suggest that an international jurisdiction over such litigations are necessary. This article aims to explore practical roadmaps to establish public international “conflict of laws” that can serve administering IP dispute resolution among MNCs. The author will start by reviewing both public international laws on IPRs including the Paris Convention, PCT, the Geneva Convention, the TRIPs, and their private counterparts. Institutional aspects of the WTO and the WIPO administering such as public international IP laws will also be examined. Agreeing with the proposed idea of establishing ‘public’ private international IP laws, this article will propose a more practical roadmap to establish time and cost efficient IP dispute resolution mechanism: the IP5 Collaboration Model.
