The mutual agreement procedure and arbitration of double taxation disputes

It is in the interest of most states to eliminate double taxation (i.e. the payment of the same tax in two jurisdictions) of transnational commercial enterprises. Because such disputes involve, on the one hand, the state imposition of taxes, a right universally asserted by all states, and private entities on the other, taxation disputes between such parties are not, on their face, easily susceptible to arbitration. This article analyzes two dispute settlement procedures-the OECD First Model Tax Convention and a similar EU Convention-with the exclusive focus on disputes relating to the imposition of double taxation. It will look at the ways in which state roles may vary under these procedures from assisting in the negotiation process to taking a part similar to, but with important differences from, diplomatic protection on behalf of an affected enterprise. The article will examine the situations under which the settlement procedure is required and/or available, how the procedures are triggered, the obligations and parts played by the parties, the means by which the disputes are resolved (from negotiations to tribunals) and the limitations of the procedures. Are they “taxpayer friendly”? As a result the reader may draw comparisons between the two procedures. Finally, the article will look at the proposed OECD Arbitration Clause which is intended to be incorporated into Article 25 of the OECD Model Tax Convention as well as how these mechanisms relate and/or conflict with bilateral tax treaties and the GATS.

Serie de documentos. Facultad de Jurisprudencia N° 71. Aspectos prácticos del proceso ante el órgano de solución de diferencias de la Organización Mundial del Comercio (OMC) y del procedimiento interno colombiano para la adopción de medidas en el ámbito internacional

La Organización Mundial del Comercio es una organización internacional que cumple una doble función. Como lo sugiere su nombre, busca la apertura en materia comercial sirviendo como foro a los Estados, para que estos puedan negociar la eliminación de barreras técnicas y económicas para el comercio. Cuenta también con un Órgano de Solución de Diferencias, fruto de un proceso de casi cinco décadas de ensayos, errores y reformas que son de vital importancia para que los Estados, sin importar su tamaño o la asimetría en temas de desarrollo, puedan participar del comercio mundial en condiciones de igualdad relativa1. Se habla de igualdad relativa y no absoluta, porque la OMC comprende que los países en vías de desarrollo necesitan tiempo, asesoría y recibir inicialmente un trato diferenciado en razón de su condición, para poder entrar a hacer parte de la cadena de comercio internacional. La Organización Mundial del Comercio se basa en la creencia firme de que el comercio internacional abierto conlleva al desarrollo, dado que incentiva la inversión extranjera directa y la expansión de las oportunidades comerciales de los productores y empresarios locales.

Friendly Settlements in the Framework of the Inter- American Human Rights System

The Inter-American system for the protection of human rights provides that disputesbetween States and victims of human rights violations or their representatives can beresolved through a friendly settlement. In this arrangement, conducted before the regionalorgans of protection of human rights, the State accepts its international responsibility,commits itself to investigate and judge the responsible and makes commitmentson compensation to the offended, the victims, on his part, renounce to take the caseto the Inter-American Court of Human Rights, and the Inter-American Commissionmonitors the legal consistency of the agreement and holds the role of independentobserver. What are these agreements, what possibilities and limitations provide to theopposing parties and, above all, what kind of reparation offer to victims of humanrights violations are issues to resolve in this article.
