Most legal systems provides the aggrieved buyer with a right to put an end to the contract. Unlike Civil Law systems, the right is rather complicated and uncertain in Common Law systems because they do not sharply distinguish between a refusal which amounts merely to a defence in the nature of the exceptio non adimpleti contractus, and one which is intended to abrogate the aggrieved party's obligations completely and to seek restitution of what he has already performed. That is, they do not draw any sharp distinction between the right of rejection or revocation and the right to put an end to the contract. This explains why the right to put an end to the contract under Civil Law systems are often compared with the right of rejection or revocation under Common Law systems in most academic papers. Having said that, this article describes and analyzes in detail the relevant UCC rules to the buyer's right of rejection and revocation, particularly the rules on the requirements for the right of rejection or revocation. This is for the purpose of providing legal advice to our sellers residing either in U.S.A. or in Korea who plan to enter into U.S.A markets and take academics' interest in the buyer's right which is deemed to be unique compared to the Civil Law systems. In addition, the study attempts to compare the rules as to the right of rejection and revocation under the UCC with those of English law which are stipulated mainly in the Sale of Goods Act (1979) in a statutory form. This may help one better to understand the rules of the UCC which are mostly originated with English law and to find in what way the rules of the UCC depart from those of English law.

최근 쌍방향성 통신 기술의 발달로 인해 인터넷 개인방송 플랫폼에 대한 수요가 증가하고 있다. 인터넷 개인방송은 시청자의 자율적인 후원금으로 수익을 창출하는데, 현재 후원행위에 관한 법률이 미비하다. 특히 미성년자가 후원을 하는 경우, 취소권을 행사할 수 있기 때문에 취소 과정에서 분쟁이 빈번하게 발생한다. 이때, 급부를 요구하는 후원행위의 경우, 일방적인 후원과 법적 성질 및 결과가 달라져 문제가 된다. 미성년자가 취소권을 행사하면 방송진행자는 급부 제공에 대한 보상은 받지 못한 채 후원금을 반환해야 하는 것이다. 본 연구는 통상적으로 증여로 인식되는 인터넷 개인방송 후원행위에서 쌍무계약성을 발견하고, 이로 인해 발생할 수 있는 방송진행자의 피해를 지적하며, 미성년자의 취소권이 배제되는 경우인 미성년자의 사술에 주목하여 관련 판례와 후원 절차를 검토하고, 미성년자의 취소권을 침해하지 않는 선에서 진행자를 보호하는 법리를 제시한다. 모호한 법리적 상황을 학문적으로 규명하고, 분쟁예방 절차를 제시하여 해당 산업에 긍정적인 영향을 가져올 수 있다.

In connected vehicles, drivers are exposed to attacks when they communicate with unauthenticated peers. This occurs when a vehicle relies on outdated information resulting in interactions with vehicles that have expired or revoked certificates claiming to be legitimate nodes. Vehicles must frequently receive or query an updated revoked certificate list to avoid communicating with suspicious vehicles to protect themselves. In this paper, we propose a scheme that works on a highway divided into clusters and managed by roadside units (RSUs) to ensure authenticity and preserve hidden identities of vehicles. The proposed scheme includes four main components each of which plays a major role. In the top hierarchy, we have the authority that is responsible for issuing long-term certificates and managing and controlling all descending intermediate authorities, which cover specific regions (e.g., RSUs) and provide vehicles with short-term pseudonyms certificates to hide their identity and avoid traceability. Every certificate-related operation is recorded in a blockchain storage to ensure integrity and transparency. To regulate communication among nodes, security managers were introduced to enable authorization and access right during communications. Together, these components provide vehicles with an immediately revoked certificate list through RSUs, which are provided with publish/subscribe brokers that enable a controlled messaging infrastructure. We validate our work in a simulated smart highway environment comprising interconnected RSUs to demonstrate our technique's effectiveness.

European Commission drafted and proposed the Common European Sales Law(CESL) to the European Parliament for the realization of a uniform set of international private law rules within the EU internal market. Since its purpose is for free international commercial activities for the sale of goods, for the supply of digital content and for related services, it was proposed to enable EU Member States to adopt or supplement as their substantive law according to their options. This study is relate to the legal bases on termination of a contract under CESL, they are composed of three parts: damages and interest, restitution and prescription. Damages and interest are divided into damages, general provisions on interest on late payments, and late payment by traders. Damages are explained by dividing into right to damages, general measure of damages, foreseeability of loss, loss attributable to creditor, reduction of loss, substitute transaction, and current price. Restitution is described by dividing into restitution on revocation, payment for monetary value, payment for use and interest on money received, compensation for expenditure and equitable modification. Prescription is explained by dividing into general provisions, periods of prescription and their commencement and extension of periods of prescription. General provisions explain right subject to prescription into a right to enforce performance of an obligation and any right ancillary to such a right. Regarding period of prescription, the short one is two years and the long one is ten years. However, in the case of a right to damages for personal injuries, period of prescription for such right is thirty years. Regarding commencement, the short one begins to run from the time when the creditor has become, or could be expected to have become, aware of the facts as a result of which the right can be exercised, while the long one begins to run from the time when the debtor has to perform. However, in the case of a right to damages, the CESL clarifies that it begins to run from the time of the act which gives rise the right.

An arbitrator in Pakistan is required to file an arbitral award in a civil court of competent jurisdiction for its recognition and enforcement if an arbitral award is domestic or before the concerned High Court if the arbitral award is international. The court of law is required to issue a decree upon submitted arbitral award if an interested party do not apply for modification or remission of an arbitral award and do not challenge it for setting it aside or for revocation of its recognition and enforcement within a prescribed time limit. The challenging process of an arbitral award can be started by the aggrieved party of an arbitration agreement at the seat of arbitration or at the place where recognition and enforcement of an arbitral award is sought. The aggrieved party to an arbitration agreement is required to challenge an arbitral award within a prescribed time limit if contracting parties have not excluded the right to challenge an arbitral award. Limitation for challenging an arbitral award in Pakistan is 30 days under article 158 of the Limitation Act 1908, starting from the date of service of notice of filling of an arbitral award before the court of law. Generally, 90 days are given for an appeal against decision of the civil court of law under section 96 of the Code of Civil Procedure 1908, it is therefore highly recommended that challenging time of an arbitral award should be increased from 30 to 90 days.

CISG provides a uniform framework for contracts of sale of goods between parties whose places of business are in different States. In 2004 South Korea became the 63th State around world to adopt CISG. Starting next year CISG goes into effect as the law that governs the contracts for international sale of goods, in respect of which CISG displaces the existing domestic civil and commercial codes of Korea. By its provision Article 1(a), CISG applies directly between Contracting States without reference to private international law. As South Korea's biggest trade partners including China, the U.S. and Japan are also parties to CISG, the number of such direct applications continuously increases. Now it is estimated, though roughly, that CISG governs about two-thirds of Korea's import and export trade of goods. The private survey of the author shows that up to now in South Korea there are 39 court cases decided by the first instance courts, 29 cases by the appellate court and six cases by the Supreme Court of South Korea. In nearly all these cases, CISG applied directly. Furthermore, currently CISG is, in several respects, influencing upon the revision of Korean civil code which is designed to modernize it: The revised draft published in 2013 adopts the rules on the revocation of offers provided in articles 15 and 16, the rule on the termination of offers provided in article 17 and the rule on the time that an acceptance takes its effect provided in article 18 of CISG. More importantly, in accordance with the rules taken by CISG, the revision draft no longer requires the existence of fault or negligence on behalf of the breaching party in order for the aggrieved party to void the contract, and the revised draft denies the right of avoidance for trivial, not fundamental, breaches of contract.

The Supreme Court stand in the position in specific lawsuit that it doesn't allow the discretionary not covered service, but recently in revocation suit of fine disposal that is imposed on medical fee of leukemia patient, it altered the existing adjudgement and admitted the discretionary not covered service exceptionally. It put forward the allowable condition roughly in that case. According as this alteration, it has become more important to embody the allowance conditions of exceptions. The Supreme Court presented three things, which are procedural condition, medical condition and subscriber's agreement. Concerning procedural condition, several present conciliation procedures are as follows: medical care benefit arret request, relative value conciliation etc, prior request on anti-cancer drug among chemicals which exceed acceptance criteria, request of non benefit object on common drugs. To be granted the existence of those system, there should be no obstacle to use that. Even if it were so, we should take circumstances into consideration; individual situation is unescapable concerning substance and urgency of the discretionary not covered service, process of the procedure, time required etc. Regarding medical condition, safety and effectiveness will be verified through evaluation procedures of new medical skill. About the necessity, the Supreme Court made clear through a sentence that it allow the discretionary not covered service, in case that needs to treat a patient out of the standard of medical benefit. Strict interpretation is right and it answer the purpose of the sentence that the supreme court permit the discretionary not covered service, exceptionally. We need to differentiate medical necessity and medical validity. Subscriber's agreement should holds true if it entails full explanation, and if it is preliminary, explicit and individual. On this account, it should be difficult to admit that someone agree effectively when he call for the affirmation that he is recipient of medical care. Reasonable expense needs to be a part of review whether the agreement is valid. Meanwhile If we adjust system of medical expense and eventually reorganize a fee for consultation payment system (Fee-for-service controlled by item to DRG (Diagnosis Related Groups)), controversial area of the discretionary not covered service will be decreased and that will guarantee the discretion of the doctor.
