The Supreme Court’s Understanding of Federalism: Efficiency at the Expense of Diversity

This paper is an examination of the Supreme Court of Canada's interpretation of federalism since constitutional repatriation in 1982. It argues that the lure of centralist efficiency is overpowering a fundamentally important part of our federal order: regionalism. The author contends that changes made by the Court to certain fundamental concepts of Canadian constitutional law now provide Parliament with greater latitude than before in the exercise of its legislative powers. According to the author, these changes are disturbing because they are structured so as to preclude consideration of the legitimate concerns of regional polities. Furthermore, he argues that the Court has reinforced the central government's power to regulate the economy, including intraprovincial matters affecting trade, by resorting to highly functional tests that emphasize economic efficiency over other criteria. This, he claims, makes it more difficult to invoke legitimate regional interests that would lead to duplication, overlapping and even, in the eyes of some, inefficiency. The author the focuses on the Court's treatment of environmental protection in an attempt to show the tension between the Court's desire to use a functional approach and the need to recognize regional interests. Finally, through an examination of recent case law, he attemps to demonstrate that the Court's dominant perspective remains functional despite its endorsement of a more community-oriented undestanding of federalism in Secession Reference. If the Court chooses to proceed in this manner, it will alienate regional polities and may encourage them to choose more radical means of asserting their differences. Further, the author argues that strict adherence to the functional effectiveness approach will undermine the very values that federalism is meant to promote.

Regional Variations in Political Ideology in Canada

Il est reconnu que les résultats électoraux au Canada varient grandement selon la région. Afin de trouver des explications à ce phénomène, il convient d’étudier comment les grandes régions du Canada se distinguent les unes des autres sur le plan politique. La présente recherche amorce cette étude sous l’angle de l’idéologie. Elle tente de déterminer en quoi l’idéologie politique diffère d’une région à l’autre du pays. Elle s’appuie sur les données des études électorales canadiennes de 2008. On a recours à des questions évaluant les préférences des répondants par rapport à plusieurs enjeux politiques pour répondre à la question de recherche. On conduit en premier lieu une analyse factorielle, qui identifie six facteurs qui ont structuré l’opinion publique lors de l’élection de 2008. Ensuite, des tests T sont conduits pour vérifier si les moyennes de ces facteurs idéologiques sont statistiquement différentes d’une région à l’autre. Les résultats montrent que les différences régionales sont souvent significatives et suivent les hypothèses. Toutefois, les résultats touchant à la privatisation de la santé ainsi qu’au Manitoba et à la Saskatchewan vont à l’encontre des attentes.

Conflicto regional, estado central y sociedad periférica en Bolivia y Perú : un análisis histórico comparado.

Cette thèse porte sur les conflits entre centres et périphéries à l’intérieur des pays. Ces dernières années, de nombreux États ont vu l'émergence de régions ou territoires qui défient leurs «centres» politiques. Ces disputes peuvent atteindre divers degrés d'affrontement, en allant des simples divisions électorales à la sécession d'une périphérie rebelle. Pourquoi certaines régions défient-elles ouvertement leur centre, tandis que d'autres ne le font pas? Dans quelles conditions les différences entre le centre et les périphéries sont-elles maîtrisées et circonscrites, et quelles sont celles qui les exacerbent? La thèse cherche à répondre à ces questions en analysant les cas de la Bolivie et du Pérou. En Bolivie, pendant les années 2000, le conflit régional a donné lieu à un clivage entre centre et périphérie; au Pérou, malgré les similitudes avec la Bolivie, un clivage similaire ne s’est pas déployé. Pourquoi cette différence? La thèse répond à la question par une analyse historique comparée. Elle suggère que les conflits entre le centre et les périphéries doivent s’analyser à partir de la combinaison de deux dimensions. La première est l’absence ou la présence d’élites régionales qui, à partir d'organisations et de mises en discours qu'elles rendent légitimes, définissent et représentent les revendications de la région et négocient avec l'État central. La deuxième dimension renvoie aux conditions structurelles de la région, en particulier l'importance des ressources naturelles et la taille de sa population. La thèse développe une analyse historique de la façon dont les deux dimensions ont évolué en Bolivie et au Pérou au cours de la seconde moitié du XX siècle. Cette analyse permet d’expliquer la divergence entre les résultats dans chacun des cas, et de suggérer des réflexions plus générales sur les relations entre les centres et les périphéries.

Which Legal Standards Should Apply To Web-logs? The present legal position of Internet journals in the European iuris prudence in the light of the European Parliament Committee’s on Culture and Education report and Polish Supreme Court decision

The article discusses the present status of weblogs and examines whether legal standards applicable to traditional press and media should be applied to that specific forum. The analysis is based on two key documents: the Draft Report on the concentration and pluralism in the media in European Union (2007/2253(INI)) of the European Parliament Committee on Culture and Education presented in March 2008 and a landmark decision of the Polish Supreme Court from July 26, 2007 (IV KK 174/07) in the light of present judicial tendency in other European countries. The first of the mentioned documents calls for the “clarification of the legal status of different categories of weblog authors and publishers as well as disclosure of interests and voluntary labelling of weblogs”. It emphasizes that the “undetermined and unindicated status of authors and publishers of weblogs causes uncertainties regarding impartiality, reliability, source protection, applicability of ethical codes and the assignment of liability in the event of lawsuits”. The position of the European Parliament, expressed in the document, raises serious questions on the limits of freedom of thought and speech on the Internet and on the degree of acceptable state control. A recent Polish Supreme Court decision, which caused quite a stir in the Polish Internet community, seems to head in the very direction recommended by the EP Culture Committee. In a case of two editors of a web journal (“czasopismo internetowe”) called “Szyciepoprzemysku”, available on-line, accused of publishing a journal without the proper registration, the Polish Supreme Court stated that “journals and periodicals do not lose the character of a press release due solely to the fact that they appear in the form of an  Internet transmission”, and that ‘’the publishing of press in an electronic form, available on the Internet, requires  registration”. The decision was most surprising, as prior lower courts decisions declined the possibility to register Internet periodicals. The accused were acquitted in the name of the constitutional principle of the rule of law (art. 7 of the Polish Constitution) and the ensuing obligation to protect the trust of a citizen to the state (a conviction in this case would break the collateral estoppel rule), however the decision quickly awoke media frenzy and raised the fear of a need to register all websites that were regularly updated. The spokesman of the Polish Supreme Court later explained that the sentence of the Court was not intended to cause a mass registration of all Internet “periodicals” and that neither weblogs nor Internet sites, that were regularly updated, needed registration. Such an interpretation of the Polish press law did not appear clear based only on the original text of the judgment and the decision as such still raises serious practical questions. The article aims to examine the status of Internet logs as press and seeks the compromise between the concerns expressed by European authorities and the freedom of thought and speech exercised on the Internet.

Systemic and regional hemodynamics in pigs with acute liver failure and the effect of albumin dialysis.

OBJECTIVE: Acute liver failure (ALF) is haemodynamically characterized by a hyperdynamic circulation. The aims of this study were to investigate the systemic and regional haemodynamics in ALF, to measure changes in nitric oxide metabolites (NOx) and to evaluate whether these haemodynamic disturbances could be attenuated with albumin dialysis. MATERIAL AND METHODS: Norwegian Landrace pigs (23-30 kg) were randomly allocated to groups as controls (sham-operation, n = 8), ALF (hepatic devascularization, n = 8) and ALF + albumin dialysis (n = 8). Albumin dialysis was started 2 h after ALF induction and continued for 4 h. Systemic and regional haemodynamics were monitored. Creatinine clearance, nitrite/nitrate and catecholamines were measured. A repeated measures ANOVA was used to analyse the data. RESULTS: In the ALF group, the cardiac index increased (PGT < 0.0001), while mean arterial pressure (PG = 0.02) and systemic vascular resistance decreased (PGT < 0.0001). Renal resistance (PG = 0.04) and hind-leg resistance (PGT = 0.003) decreased in ALF. There was no difference in jejunal blood flow between the groups. ALF pigs developed renal dysfunction with increased serum creatinine (PGT = 0.002) and decreased creatinine clearance (P = 0.02). Catecholamines were significantly higher in ALF, but NOx levels were not different. Albumin dialysis did not attenuate these haemodynamic or renal disturbances. CONCLUSIONS: The haemodynamic disturbances during the early phase of ALF are characterized by progressive systemic vasodilatation with no associated changes in metabolites of NO. Renal vascular resistance decreased and renal dysfunction developed independently of changes in renal blood flow. After 4 h of albumin dialysis there was no attenuation of the haemodynamic or renal disturbances.
