The recent decision of the Supreme Court of Canada in Societyof Composers, Authors and Music Publishers of Canada v CanadianAssociation of Internet Providers [2004] 2 SCR 427 is significantfor two reasons: (a) the Canadian Supreme Court held that InternetService Providers should be exempted from copyright liabilityas long as they provide only a conduit service in transmittingcopyright materials between Internet users (a point which isconsistent with many national copyright laws); (b) the majorityof the Canadian Supreme Court arrived at the conclusion thatthe appropriate test to determine whether an infringement forthe unauthorized transmission of online copyright material hasoccurred within the Canadian jurisdiction is the ‘realand substantial connection’ test (LeBel J, however, dissentedand was of the view that the correct test to apply is the ‘hostserver’ test). This paper studies these two tests as propoundedby the Canadian Supreme Court and assesses their strengths andweaknesses, especially in light of the territoriality principlein copyright law.  相似文献

Thromboembolic events in the context of carbon monoxide (CO) exposure have been well described in the literature. Six cases of clinically significant coronary thrombosis following CO exposure were previously reported. However, factors affecting the development of coronary thrombus in CO exposure are poorly understood, and the significance of this finding in a forensic context is not clear. This article discusses a case of coronary thrombosis found at autopsy following a death in which CO poisoning was suspected. A 67‐year‐old man was found dead in his garage with four vehicles with their ignition in the “on” position and their tanks empty. At autopsy, severe coronary atherosclerosis and an acute nonocclusive coronary thrombus were found. Given the dissimilarities among cases and the presence of CO exposure, it was suggested that the coronary artery thrombosis is likely due to the inherent prothrombotic mechanism of CO, the only common denominator in all the cases.  相似文献

VNTR D1S80 locus genotyping has been largely replaced in forensics by STR. As the statute of limitations on murder cases was abolished in the Republic of Korea in July 2015, the demand for re‐analysis of DNA from unresolved murder cases has increased. The National Forensic Service includes several recorded D1S80 genotypes as crucial clues. Here, we re‐established the D1S80 analysis system using capillary electrophoresis and confirmed the reproducibility of the system by comparison with the genotypes of eight DNA samples that had been analyzed using PAGE in 2006. In addition, we created an allelic ladder via new methodology using flanking region sequences. A single DNA sample (K562) and seven primers were used for the new ladder, which contains 12 alleles. Although artificial owing to the use of the flanking region rather than repeat unit reduction, the method is rapid and simple, and could be applicable in any laboratory.  相似文献
