this short article intends to conduct an analysis regarding the application of legal institutions from the protection of international investments laws in colombia, based on two main hypotheses: the enactment of measures by the state that have as purpose or effect the harm of an investment in a port concession under a free trade zone regime. hence, from the institutions of expropriation and minimum standard of treatment, we'll study the possibility to invoke a bilateral investment treaty to obtain compensation from the state. we'll include some other local legal institutions with the purpose of studying the implications of the risk clause in colombian port concessions contracts.
