The Convention on the Protection and Promotion of the Diversity of Cultural Expressions, adopted under the auspices of the United Nations Educational, Cultural and Scientific Organization (UNESCO) in 2005, entered into force on 18 March 2007 after an incredibly swift ratification process. The Convention is the culmination of multiple-track efforts that spread over many years with the objective of providing a binding instrument for the protection and promotion of cultural diversity at the international level. These efforts, admirable as they may be, are not however isolated undertakings of goodwill, but a reaction to economic globalisation, whose advancement has been significantly furthered by the emergence of enforceable multilateral trade rules. These very rules, whose bearer is the World Trade Organization (WTO), have been perceived as the antipode to "culture" and have commanded the formulation of counteracting norms that may sufficiently "protect" and "promote" it. Against this backdrop of institutional tension and fragmentation, the present chapter explicates the emergence of the concept of cultural diversity on the international policy- and law-making scene and its legal dimensions given by the new UNESCO Convention. It critically analyses the Convention's provisions, in particular the rights and obligations of the State Parties, and asks whether indeed the UNESCO Convention provides a sufficient and appropriate basis for the protection and promotion of a thriving and diverse cultural environment.

This chapter discusses the relationship between labour market regulation and regional trade agreements from both a legal and an economic angle. We examine empirically whether regional trade liberalisation is associated with deterioration (“race to the bottom”) of domestic labour standards beyond those reflected in the 1998 ILO Declaration on the Fundamental Principles and Rights at Work. Using a panel of 90 developed and developing countries, covering the years from 1980 to 2005, we find that after the entry into force of a regional trade agreement (RTA), labour standards applying to employment protection and unemployment benefits are significantly weakened. We show that such a lowering of protection levels tends to occur in high income countries and that this effect mainly stems from RTAs among such countries rather than with low or middle income countries. Concern about competitive pressure to weaken domestic labour regulation is reflected in a variety of undertakings in RTAs not to administer labour laws with a view to improving one’s competitive position in trade or foreign direct investment (FDI). The above-mentioned empirical findings indicate that such provisions could potentially become relevant, and that this is more likely to be the case for high income members of RTAs. Our analysis, from a legal point of view, of relevant institutional and procedural mechanisms indicates however that enforceability of the relevant provisions is weak for most of the existing legal texts.

Insufficient and unrepresentative participation in voluntary public hearings and policy discussions has been problematic since Aristotle's time. In fisheries, research has shown that involvement is dominated by financially resourceful and extreme-opinion stakeholders and tends to advantage groups that have a lower cost of attendance. Stakeholders may exhibit only one or all of these traits but can be still similarly advantaged. The opposites of these traits tend to characterize the disadvantaged, such as the middle-ground opinions, the less wealthy or organized, and the more remote stakeholders. Remoteness or distance is the most straightforward and objective of these characteristics to measure. We analyzed the New England Fishery Management Council's sign-in sheets for 2003-2006, estimating participants' travel distance and associations with the groundfish, scallop, and herring industries. We also evaluated the representativeness of participation by comparing attendance to landings and permit distributions. The distance analysis showed a significant correlation between attendance levels and costs via travel distance. These results suggest a potential bias toward those stakeholders residing closer to meeting locations, possibly disadvantaging parties who are further and must incur higher costs. However, few significant differences were found between the actual fishing industry and attendee distributions, suggesting that the geographical distribution of the meeting attendees is statistically similar to that of the larger fishery. The interpretation of these results must take into consideration the limited time span of the analysis, as policy changes may have altered the industry make-up and location prior to our study. Furthermore, the limited geographical input of stakeholders may lend bias to the Council's perception of ecological and social conditions throughout the spatial range of the fishery. These factors should be further considered in the policy-formation process in order to incorporate a broader range of stakeholder input.

This is an ethnographic study about the worldview of community-based initiatives in Houston, Texas, and the people who work in them. People who participated in this study recognize that their direct constructive action is at the heart of authentic social change in their minority communities. Through qualitative data analysis, a constellation of relationships and process patterns were found to constitute themselves into the system of the community-based initiative. The predominant patterns identified from the findings in this study are: the pervasiveness of place, the importance of people, unique initiatory patterns, the concrete local sustainability, the ever-present action orientation, the resourceful use of networks and inter-relationships, the significance of church influence, the core sense of spirituality and the essence of hope. These patterns emerged out of the local knowledge, which is acutely sensitive to the elements of history and lived experience, embedded in the distinctive moral and visionary patterns of meaning and expression. Findings from the research reveal that these community-based initiatives are not programs--they are people--people who keep hope alive in their communities and who, by their daily practice, liberate others. ^

La infiltración de agua en el suelo y la recarga profunda del agua subterránea contenida en los acuíferos es un proceso lento en relación con otros fenómenos hidrológicos. La redacción de esta tesis ha pretendido contribuir al estudio de la influencia que el almacenamiento de la precipitación sólida en forma de manto de nieve y su eventual fusión puedan tener sobre dicho proceso en áreas de media montaña (1.000 – 2.000 m.) en las que con gran frecuencia se sitúan las cabeceras de los ríos peninsulares. Para ello se ha partido del análisis de las diferentes variables intervinientes durante un determinado periodo temporal y sobre un espacio geográfico concreto, por lo que su metodología es de naturaleza empírica. La extensión del periodo (2002/03 a 2010/11) ha venido condicionada por la disponibilidad de los valores de algunas de sus principales variables, como han sido el equivalente en agua de la nieve acumulada y los caudales procedentes de su fusión. Éstos se han obtenido como resultado de la aplicación del modelo ASTER, desarrollado en el programa de Evaluación de los Recursos Hídricos procedentes de la Innivación (ERHIN), calibrado – entre otros- con datos de precipitaciones, temperatura y caudales provenientes a su vez del Sistema Automático de Información Hidrológica (SAIH). Ambos programas fueron implantados por la Administración en las diferentes Confederaciones Hidrográficas y en determinados Organismos de cuenca actuales, en cuyo desarrollo participó el autor de esta tesis. En cuanto a la zona de estudio se ha procedido a su elección considerando las posibles áreas de media montaña en las que la presencia de la nieve fuera hidrológicamente significativa y estuvieran constituidas litológicamente por afloramientos permeables que no impidieran la infiltración en el terreno y la formación de acuíferos de cierta relevancia. El interés se centró discrecionalmente en la cuenca del Tajo, tanto por el carácter estratégico de la misma -como suministradora en la actualidad de excedentes a otras cuencas deficitarias- como por el valor representativo de sus condiciones climáticas y orográficas en relación con otras cuencas hidrográficas peninsulares. Para ello se partió de las cabeceras de ríos identificadas por el programa ERHIN por su interés nivológico para la implantación del modelo ASTER y de las Masas de Agua Subterráneas MASb (antes Unidades Hidrogeológicas UUHH) definidas en los planes hidrológicos. La intersección en el territorio de ambos criterios condujo, finalmente, a la zona del Alto Tajo, en la que se cumplen ambos requisitos. El tramo quedó concretado en el comprendido entre las cabeceras de los ríos Tajo y Guadiela y la cola de los embalses de Entrepeñas y Buendía respectivamente, puntos de cierre para la calibración llevada a cabo en la modelización ASTER. Gran parte de éste discurre, en su parte alta, sobre rocas carbonatadas (calizas y dolomías del Jurásico y Cretácico), relacionados con las MASb de Tajuña-Montes Universales, Molina de Aragón y Sigüenza-Maranchón. Los valores diarios de las reservas de agua en forma de nieve, evapotranspiración y caudales procedentes de la fusión se han obtenido a partir de los resultados del mencionado modelo, procediéndose al cálculo de la infiltración por balance hídrico durante el periodo de estudio considerado, teniendo en cuenta los valores de precipitación, evapotranspiración y aportaciones de caudales. Esto ha requerido el estudio previo de las condiciones hidrogeológicas de la zona seleccionada con objeto de conocer las posibles interconexiones subterráneas que pudieran alterar los saldos entre las variables intervinientes anteriormente citadas. Para ello se ha llevado a cabo la recopilación y análisis de la información hidrogeológica correspondiente a la documentación de los planes hidrológicos del Tajo (Plan Hidrológico de la cuenca del Tajo RD 1664/1998 y el actual Plan Hidrológico de la parte española de la Demarcación Hidrográfica del Tajo RD 270/2014) y de los estudios previos realizados por el organismo de cuenca y el Instituto Geológico y Minero de España (lGME) fundamentalmente. En relación con la MASb Tajuña-Montes Universales -cuya extensión supera la zona seleccionada- dichos estudios consideran su estructura geológica y distribución litológica, con intercalaciones impermeables que actúan como barreras, dividiendo a éstas en Subunidades e identificando las zonas de drenaje de sus respectivos acuíferos. También se ha considerado la documentación y estudios previos del Plan Hidrológico Nacional sobre las Unidades Hidrogeológicas compartidas entre ámbitos geográficos de diferentes planes hidrológicos. Se concluye que las divisorias hidrográficas de las cabeceras son sensiblemente coincidentes o abarcan las Subunidades Montes Universales meridionales, Priego, Cifuentes, Zaorejas, u Montes Universales septentrionales, que drenan hacia el Tajo/Guadiela (bien directamente, bien a través de afluentes como el Gallo, Ablanquejo, Cabrillas, Cuervo…), MASb Molina de Aragón, que drena al Tajo a través del río Gallo y MASb Sigüenza—Maranchón, que drena su parte correspondiente hacia el Tajo a través del Ablanquejo. Se descartan – salvo la pequeña salvedad del manantial de Cifuentes- las conexiones hidrogeológicas con otras MASb o Subunidades por lo que las cabeceras del Tajo y del Guadiela pueden considerarse como un Sistema independiente donde las precipitaciones no evaporadas escurren superficialmente o se infiltran y descargan hacia los embalses de Entrepeñas y Buendía. La cuantificación diaria y acumulada de los balances hídricos ha permitido calcular la evolución aproximada de las reservas de agua subterránea desde la fecha inicial. Originalmente los balances se realizaron de forma separada en las cabeceras del Tajo y del Guadiela, cuyos valores acumulados manifestaron una tendencia creciente en la primera y decreciente en la segunda. Dicha situación se equilibra cuando el balance se practica conjuntamente en ambas, apreciándose en la variación del volumen de agua subterránea una evolución acorde hidrológicamente con los ciclos de verano/invierno y periodos de sequía, manteniéndose sus valores medios a largo/medio plazo, poniendo en evidencia la existencia de interconexiones subterráneas entre ambas cuencas. El balance conjunto, agregando la cabecera del Tajuña (que también comparte los materiales permeables de la MASb Tajuña-Montes Universales) no reveló la existencia de nuevas interrelaciones hidrogeológicas que influyeran en los balances hídricos realizados Tajo/Guadiela, confirmando las conclusiones de los estudios hidrogeológicos anteriormente analizados. Se ha procedido a confrontar y validar los resultados obtenidos de la evolución de las reservas de agua subterránea mediante los siguientes procedimientos alternativos: - Cálculo de los parámetros de desagüe de la curva de agotamiento correspondiente al volumen de agua subterránea drenante hacia el Tajo/Guadiela. Éste se ha realizado a partir de las aportaciones mensuales entrantes en los embalses de Entrepeñas y Buendía durante los meses de junio, julio, agosto y septiembre, cuyos valores responden al perfil típico de descargas de un acuífero. A partir de éstos se ha determinado el volumen drenante correspondiente al primero de junio de cada año de la serie histórica considerada. - Determinación del caudal base por el método Wallingford y deducción de los volúmenes drenantes. Estimación de las recarga anuales - Cuantificación de la recarga anual por el método Sanz, Menéndez Pidal de Navascués y Távara. Se obtuvieron valores de recarga muy aproximados entre los calculados por los dos últimos procedimientos citados. Respecto a las reservas de agua subterránea almacenadas siguen una evolución semejante en todos los casos, lo que ha permitido considerar válidos los resultados conseguidos mediante balance hídrico. Confirmada su solidez, se han buscado correlaciones simples entre el volumen de las reservas subterráneas (como indicador estimativo del efecto de la infiltración) y los volúmenes procedentes de la fusión. La conclusión es que estos últimos no tienen un efecto determinante a escala anual sobre la infiltración,recarga y variación de los volúmenes de agua subterránea, frente al peso de otras variables (precipitación y evapotranspiración). No obstante se ha encontrado una buena correlación múltiple entre la recarga estimada y la precipitación eficaz (precipitación menos evapotranspiración) y fusión, que ha permitido cuantificar la contribución de esta última. Posteriormente se ha recurrido a la selección de los episodios más intensos de acumulación /fusión en las cabeceras del Tajo y Guadiela. Y se procedió a la comparación entre los resultados obtenidos por aplicación del modelo de simulación en los mismos periodos (normalmente de varios días de duración) con datos reales y con datos ficticios de temperatura que anularan o disminuyeran la presencia de nieve, apreciándose una gran sensibilidad del efecto de la temperatura sobre la evapotranspiración y estableciéndose nuevamente correlaciones lineales entre los volúmenes de fusión y el incremento de reservas subterráneas. Las mismas confirman el efecto “favorecedor” de la acumulación de agua en forma de nieve y su posterior licuación, sobre sobre la infiltración de agua en el suelo y almacenamiento subterráneo. Finalmente se establecieron varios escenarios climáticos (+1ºC; +3ºC; +1ºC y – 10% precipitación; y 3ºC – 10% precipitación) compatibles con las previsiones del IPCC para mediados y finales del presente siglo, determinándose mediante simulación ASTER los correspondientes valores de fusión. La correlación establecida a escala anual ha permitido evaluar el efecto de la disminución del volumen de fusión - en los diferentes escenarios – sobre la recarga, pronosticando un descenso de los caudales de estiaje y la desaparición del “efecto nieve” sobre la infiltración y recarga con un aumento de 3ºC de temperatura. Teniendo en cuenta las condiciones de representatividad de la zona elegida, resulta verosímil la extensión de las anteriores conclusiones a otras cabeceras fluviales enclavadas en áreas de media montaña situadas entre 1000 a 2000m y sus efectos aguas abajo.Water infiltration into the soil and groundwater recharge deep water in aquifers is slow relative to other hydrological phenomena. The wording of this thesis aims to contribute to the study of the influence that the storage of solid precipitation as snow cover and its eventual melting may have on this process in mid-mountain areas (1000 - 2,000 m) where very often the headwaters of the peninsular rivers are located. For this party analysis of the different variables involved has over a given time period and a particular geographical area, so that their methodology is empirical in nature. The extension of the period (2002/03 to 2010/11) has been conditioned by the availability of the values of some of its key variables, as were the water equivalent of the snow and flows from melting. These have been obtained as a result of the application of ASTER model, developed in the program Evaluation of Water Resources from the Innivation (ERHIN), calibrated - among others data of rainfall, temperature and flow from turn System Automatic Hydrological Information (SAIH). Both programs were implemented by the Administration in the different Water Boards and to undertakings for current basin, in which the author participated development of this thesis. As for the study area has proceeded at its option considering the possible areas of midmountain in the presence of snow outside hydrological meaningful and they were lithology consisting of permeable outcrops that did not prevent infiltration into the ground and forming aquifers of some significance. We were interested discretion in the Tagus basin, therefore the strategic nature of it, as currently supplying surplus to other basins deficit- as the representative value of its climate and terrain conditions in relation to other peninsular river basins . To do this we started from the headwaters identified by the ERHIN program for its implementation snow interest to the ASTER model and Ground Water Bodies MASb (before UUHH Hydrogeological Units) defined in hydrological plans. The intersection in the territory of both criteria led eventually to the Alto Tajo, in which both requirements are met. The section was finalized in the period between the headwaters of the Tagus and Guadiela rivers and reservoirs end Entrepeñas and Buendia respectively checking points for calibration performed in ASTER modeling. Much of it runs on carbonate rocks (limestones and dolomites of Jurassic and Cretaceous) related MASb of Tajuña -Montes Universal, Molina de Aragón and Sigüenza-Maranchón. The daily values of water reserves in the form of snow, evapotranspiration and flow from melting were obtained from the results of this model, proceeding to the calculation of infiltration water balance during the study period considered, taking into account values of precipitation, evapotranspiration and input flow. This has required the prior examination of the hydrogeological conditions of your required in order to know the possible underground interconnections that could alter the balance between the intervening variables aforementioned area. For this we have carried out the collection and analysis of hydrogeological information relevant documentation Tagus river management plans (Hydrological Plan Tajo Basin RD 1664/1998 and the current Hydrological Plan of the Spanish part of the River Basin Tagus RD 270/2014) and previous studies by the basin organization and the Geological Survey of Spain (IGME) mainly. Regarding the MASb Tajuña- Montes Universal - whose length exceeds the area selected - these studies consider its geological structure and lithology distribution with waterproof collations that act as barriers, dividing it into subunits and identifying areas draining their respective aquifers. It has also considered the documentation and previous studies of the National Hydrological Plan on shared among different geographical areas management plans Hydrogeological Units. We conclude that river dividing the headers are substantially coincident or covering Subunits southern Universal Montes, Priego Cifuentes, Zaorejas and northern Universal Mounts, which drain into the Tagus / Guadiela (either directly or through tributaries such as Gallo, Ablanquejo , whitecaps , Raven ...), MASb Molina de Aragón which drains through the Tajo del Gallo and MASb Sigüenza- Maranchón river that drains into the Tagus using the Ablanquejo . Discarded - except the small exception of spring Cifuentes -hydrogeological connections with other MASb or Subunits so the headwaters of the Tagus and Guadiela be considered as a separate system, where rainfall not evaporated runs on surface or infiltrates and eventually discharged into reservoirs Entrepeñas and Buendia. The daily and cumulative quantification of water balances allowed us to compute the approximate evolution of groundwater reserves from its initial date. Initially balances were performed separately in the headwaters of the Tagus and Guadiela, whose cumulative values showed an increasing trend in the first and decreasing in the second. This situation is balanced when the balance is practiced together in both , appreciating the change in volume of groundwater hydrological evolution commensurate with the cycles of summer / winter and drought periods , keeping their average long / medium term values and putting in shows the existence of underground interconnections between the two basins. The overall balance, adding header Tajuña (which also shares the permeable materials MASb Tajuña -Montes Universal ) did not reveal the existence of new hydrogeological interrelationships that influenced water balances made Tajo / Guadiela, confirming the findings of the hydrogeological studies previously analyzed. We proceeded to confront and validate the results of the evolution of groundwater reserves by the following alternative procedures: - Calculate the parameters drain depletion curve corresponding to the volume of groundwater draining into the Tajo / Guadiela. This has been made from monthly inflows in the reservoirs of Entrepeñas and Buendia during the months of June, July, August and September, whose values match the typical profile of an aquifer discharges. From these has been determined for the first of June each year of the time series considered drainage volume - Determination of base flow by Wallingford method and deduction of drainage volumes. Estimate of annual recharge - Quantification of the annual recharge by the method Sanz Menéndez Pidal of Navascués and Távara. Very approximate values recharge between calculated for the last two mentioned methods were obtained. Concerning groundwater reserves stored follow a similar pattern in all cases, allowing consider valid the results achieved through water balance. Confirmed its robustness, simple correlations were sought between the volume of groundwater reserves (as estimated indicator of the effect of infiltration) and volumes from the melting. The conclusion is that the latter do not have a decisive effect on the annual scale infiltration, recharge and variation in volumes of groundwater, against the weight of other variables (precipitation and evapotranspiration). However found a good multiple correlation between the estimated recharge and effective precipitation (precipitation minus evapotranspiration) and fusion, which allowed quantify the contribution of the latter. Subsequently it has resorted to the selection of the most intense episodes of accumulation / melting in the headwaters of the Tagus and Guadiela. And we proceeded to the comparison between the results obtained by application of the simulation model in the same periods (usually several days) with real data and fictitious temperature data to annul or decrease the presence of snow, appreciating a great sensitivity of the effect of temperature on evapotranspiration and establishing linear correlations between the volumes of melting and increased groundwater reserves again. They confirm the “flattering " effect of water accumulation as snow and subsequent liquefaction of the infiltration of water into the soil and underground storage. Finally various climate scenarios (+1ºC; +3ºC; +1ºC y – 10% precipitation; y 3ºC – 10% precipitation) were established consistent with IPCC projections for mid - to late - century, determined through simulation ASTER corresponding values of melting. The correlation established on an annual scale has allowed to evaluate the effect of decreasing the volume of melt - in different scenarios - on recharge, predicting a decline in low flows and the disappearance of "snow effect" on infiltration and recharge with an increase of 3°C temperature. Given the conditions of representativeness of the chosen area, plausible extension of the above findings to other landlocked headwaters in mid-mountain areas located between 1000 to 2000m and its downstream effects.

O papel desempenhado pelo Poder Judiciário nos mais diversos Estados passa por sensível evolução ao longo do século XX, à medida que se desenvolveram os sistemas de controle de constitucionalidade. De um lado, os atores políticos assumem especial importância nesse processo. Os modelos de revisão judicial foram reforçados, no mais das vezes, em paralelo à positivação, em âmbito constitucional, de um amplo rol de direitos fundamentais e de princípios balizadores e limitadores do poder estatal. Com isso, os elementos cotejados no processo legislativo de tomada de decisões políticas são revestidos de status constitucional e transportados para o discurso argumentativo do Direito, o que leva a um processo de judicialização da Política que permite que a atividade legiferante seja passível de confronto perante instâncias judiciárias. Os instrumentos de controle de constitucionalidade assumem, assim, novos contornos, permitindo que o Judiciário interfira no conteúdo das escolhas políticas feitas pela maioria governante. De outro lado, o Poder Judiciário particularmente as Cortes Constitucionais passa a assumir a corresponsabilidade na efetivação das metas e compromissos estatais, com o que desenvolve uma política institucional mais proativa e comprometida com a concretização substancial de valores democráticos, interferindo, assim, de maneira mais incisiva e rígida no controle do processo político. A definição de políticas fundamentais e o processo legiferante passam a contar com constante participação do Judiciário. Na realidade brasileira, a Constituição de 1988 amplia as competência do Supremo Tribunal Federal em sede de controle de constitucionalidade, inserindo o órgão de maneira efetiva nesse contexto de intervenção judicial na Política. A última década, por sua vez, marcou uma perceptível mudança em sua atividade e em sua interferência no processo de tomada de decisões políticas pelos demais Poderes. Valendo-se dos diversos instrumentos de controle que lhe são disponibilizados, assumiu o compromisso de participar na efetivação dos preceitos constitucionais pátrios mediante a revisão do conteúdo normativo decorrente das escolhas políticas tomadas em outras instâncias. Desse modo, tornou-se verdadeiro copartícipe do processo de definição de políticas legislativas nacionais, seja rechaçando normas que repute inconstitucionais, seja proferindo decisões com claros efeitos normativos que buscam readequar e conformar as escolhas dos atores políticos. Nesse processo decisório, entra em jogo a intensidade com que a Corte busca impor sua visão e suas concepções no tocante à efetivação e concretização dos compromissos constitucionais. A sobreposição de ponderações judiciais e legislativas acarreta, a seu turno, importantes efeitos sistêmicos ao diálogo interinstitucional que se desenvolve entre os Poderes, em especial no que concerne à distribuição das funções estatais dentro das premissas democráticas e ao dimensionamento do papel que compete a cada um dos Poderes no processo de efetivação e proteção da Constituição.

Introduction. Meeting competition occurs when an undertaking lowers its prices in response to the entry of a competitor. Despite accepting that meeting competition can be compatible with Article 82, the Commission2 and the Court of justice3 have repeatedly condemned the practice due to the modalities of implementation or “particular circumstances”.4 However, existing precedent on the subject remains obscurely reasoned and contradictory, such that it is at the present time impossible to give clear advice to undertakings on the circumstances in which meeting competition is compatible with Article 82. Not only is such legal uncertainty in itself damaging but, in so far as it discourages meeting competition, it appears to us to be harmful to competition. As concerns the latter point, it will be seen that some of the most powerful arguments against prohibiting meeting competition are based on the counterproductive nature of the remedies. The present article does not, however, aim to propose a simple solution to distinguish abusive and non-abusive meeting competition.5 Nor does the article aim to give a comprehensive overview of the existing case law in this area.6 Instead, it takes a more economic approach and aims to lay out in a (brief but) systematic fashion the competitive concerns that might potentially be raised by the practice of meeting competition and in doing so to try to identify the main flaws in the Court and Commission’s approach.

Introduction. The essential facilities doctrine may be seen as the ‘extra weight’ which is put onto the balance, in order to give precedence to the maintenance of competition over the complete contractual freedom of undertakings controlling an important and unique facility. The main purpose of the doctrine is to impose upon such ‘dominant’ undertakings the duty to negotiate and/or give access to the facility, against a reasonable fee, to other undertakings, which cannot pursue their own activity (and therefore will perish) without access to such a facility. This very simple description of the content of the doctrine underlines its limitations: through the imposition of a duty to negotiate or contractual obligations, the rule tends to compensate for the weaknesses of the competitive structure of a market, which are due to the existence of some essential facility. In other words, the doctrine does not by itself provide a definitive solution to the lack of competition, but tends to contractually maintain or even create some competition.1 The doctrine of essential facilities originates in the US antitrust case law of the Circuit and District Courts, but has never been officially acknowledged by the Supreme Court. It has been further developed and hotly debated by scholars in the US, both from a legal and from an economic viewpoint. In the EU, the essential facilities doctrine was openly introduced by the Commission during the early 1990s, but has received only limited and indirect support by the Court of First Instance (the CFI) and the European Court of Justice (the ECJ). It also indirectly inspired the legislation concerning the deregulation of traditional ‘natural’ monopolies. The judicial origin of the doctrine, combined with the hesitant application by the appeal courts, both in the US and the EU, cast uncertainty not only on the precise scope of the doctrine, but also on the issue of its very existence. These questions receive a particular light within the EU context, where the doctrine is called upon to play a different role from its US counterpart. In order to address the above issues, we will first pretend that an EU essential facility doctrine does indeed exist and we shall try to identify the scope and content thereof, through its main applications (Section 1). Subsequently, we will try to answer the question whether such a doctrine should exist at all in the EU (Section 2).

The adoption of the euro in January 2011 topped off Estonia’s integration policy. In the opinion of Estonian politicians, this country has never been so secure and stable in its history. Tallinn sees the introduction of the euro primarily in the political context as an entrenchment of the Estonian presence in Europe. The process of establishing increasingly close relations with Western European countries, which the country has consistently implemented since it restored independence in 1991, has been aimed at severing itself its Soviet past and at a gradual reduction of the gap existing between Estonia and the best-developed European economies. The Estonian government also prioritises the enhancement of co-operation as part of the EU and NATO as well as its principled fulfilment of the country’s undertakings. It sees these as important elements for building the country’s international prestige. The meeting of the Maastricht criteria at the time of an economic slump and the adoption of the euro during the eurozone crisis proved the determination and efficiency of the government in Tallinn. Its success has been based on strong support from the Estonian public for the pro-European (integrationist) policy of Estonia: according to public opinion polls, approximately 80% of the country’s residents declare their satisfaction with EU membership, while support for the euro ranges between 50% and 60%. Since Estonia joined the OECD in 2010 and adopted the euro at the beginning of 2011, it has become the leader of integration processes among the Baltic states. The introduction of the euro has reinforced Estonia’s international image and made it more attractive to foreign investors. The positive example of this country may be used as a strong argument by the governments in Lithuania and Latvia when they take action to meet the Maastricht criteria. Vilnius and Riga claim they want to adopt the euro in 2014. The improving economic situation in the Baltic states will contribute to the achievement of this goal, while an excessively high inflation rate, as in 2007, may be the main impediment1.
