The present research is meant to find out some of the factors that influence the Ecuadorian Highest Courts decisions in environmental cases. For answering my research question I analyzed these decisions, from 1998 to 2014, which constitutes the whole population of the decisions in environmental cases. For the Capstone, I focused in oil and mining cases. The research required three steps. First was to collect data from the corps of decisions in the national Court cases. Second, was to design a database: create variables and a codebook to organize them. Third, was to develop an analysis model using this data and investigate whether there are causal or correlations between the variables. I build the model with one dependable variable that summarized the case results (Variable: decision). The findings showed not only correlations between the independent variables such as the subject that tried to enforce the environmental rights, but also causation between a ‘pro environment decision’ (hereafter PER) or an ‘against environment decision’ (hereafter AER) and the topic that was discussed.
