O direito de exoneração do acionista minoritário

This study specifically addresses the situation of minority shareholders after the transfer of control in an listed company. The various underlying interests and reasons that shareholders have for investing in a company can demonstrate shareholders’ reasoning for taking radically different positions on issues relating to the transfer of control of the referred company. This study analyses the current legal system in Portugal and in the European Union in order to assess whether, in the event of a takeover bid of a listed company where there is a transfer of control, minority shareholders have the same appraisal rights as other shareholders to sell their shares and leave the company. The study then examines the European Court of Justice decision on whether a general principle of equal treatment of minority shareholders exists upon a transfer of control (Audiolux) and the Portuguese Securities Market Commission decision regarding the delisting of Brisa - Autoestradas de Portugal, S.A. based on the principle of investor protection. The study concludes that although the principle of equality amongst shareholders has made progress in the European legal system e.g. it is laid down in Directive 2004/25/EC of 21 April 2004 on takeover bids and the Portuguese Securities Market Code, there is also a need for further improvement, which can be accomplished by allowing minority shareholders to exercise an appraisal right in similar unregulated situations.

O direito de arrependimento nos contratos celebrados à distância e fora do estabelecimento

This dissertation aims to analyze the right of withdrawal and its implications on distance and off-premises contracts, due to the importance of these contracts in our society. Our main goal is, first of all, to explain the meaning and characteristics of both distance and off-premises contracts and the reason why a right of withdrawal is granted. Secondly, we intend to explain all of the relevant aspects related to this right, such as its legal concept and main characteristics, the origin and evolution of the right of withdrawal on both European and Portuguese legislation, its implications in the contracting parties and, finally, a brief analysis of the applicable law. In a nutshell, the right of withdrawal allows the consumer to withdraw from a distance or off-premises contract, unilaterally, without having to indicate any motive to justify the decision, after a cooling-off period of 14 calendar days. In these two types of contracts such right exists due to the reasons or circumstances that lead to the conclusion of the contract.

Direito a ser esquecido na internet

With the recent technological development, we have been witnessing a progressive loss of control over our personal information. Whether it is the speed in which it spreads over the internet or the permanent storage of information on cloud services, the means by which our personal information escapes our control are vast. Inevitably, this situation allowed serious violations of personal rights. The necessity to reform the European policy for protection of personal information is emerging, in order to adapt to the technological era we live in. Granting individuals the ability to delete their personal information, mainly the information which is available on the Internet, is the best solution for those whose rights have been violated. However, once supposedly deleted from the website the information is still shown in search engines. In this context, “the right to be forgotten in the internet” is invoked. Its implementation will result in the possibility for any person to delete and stop its personal information from being spread through the internet in any way, especially through search engines directories. This way we will have a more comprehensive control over our personal information in two ways: firstly, by allowing individuals to completely delete their information from any website and cloud service and secondly by limiting access of search engines to the information. This way, it could be said that a new and catchier term has been found for an “old” right.

O abuso do direito no Direito do Consumo

In Consumer Law there is a special concern to protect the consumer, who is the weaker party in the legal relationship. With this thesis we intend to show that the professional sometimes needs protection against abusive conducts from consumers. The thesis describes the different categories of abuse of rights and explains some types of consumer contracts. After examining some of the consumer’s rights, we list some situations where the consumer acts frequently with abuse of rights, by analyzing judicial decisions. We conclude that it is not possible which conducts may involve an abuse of right in an abstract manner. Only by analyzing every case and its characteristics individually can one decide where there is an abuse of right.

A importância das infraestruturas ferroviárias na intermodalidade marítimo-ferroviária do transporte de mercadorias

Esta dissertação é elaborada numa época em que cada vez mais se discute a necessidade de avaliar a importância dos investimentos em infraestruturas de transportes, designadamente de forma a conseguir-se otimizar a intermodalidade entre os diversos modos. O transporte ferroviário de mercadorias em Portugal desempenha um papel de menor relevo comparativamente com os transportes marítimo e, particularmente, rodoviário. Este, tem sido utilizado excessivamente quando, não raras vezes, poderia ser substituído pelo transporte ferroviário, reduzindo, deste modo, as externalidades negativas inerentes à rodovia. No caso do transporte de mercadorias, urge encontrar soluções que promovam a intermodalidade, nomeadamente entre os modos marítimo e ferroviário, seja pelos benefícios ambientais e sociais que daí advêm, seja pelo potencial económico ligado às exportações. Este trabalho compreende, como contribuição central, a abordagem e análise de dois casos de estudo que ajudam a confirmar a importância e a relevar o contributo do transporte ferroviário de mercadorias na intermodalidade marítimo-ferroviária. Num dos casos de estudo, é possível fazer a comparação entre as intermodalidades marítimo-ferroviária e marítimo-rodoviária para o mesmo tipo e volume de mercadoria expedida. Simultaneamente, é feita a apresentação de duas propostas de infraestruturas ferroviárias que visam promover a intermodalidade marítimo-ferroviária. Com base neste trabalho, foi possível salientar a importância do transporte ferroviário no transporte de mercadorias, particularmente na ligação aos portos, resultando claro que encerra mais vantagens face ao transporte rodoviário.
