This research aims to analyze the reflections of the Emergency and Transitional Legal Regime (RJET), governed by Law No. 14,010/2020, within the scope of the Court of Justice of Mato Grosso (TJMT). That temporary law was to regulate the effects of private relations in the context of the pandemic of the new coronavirus (COVID-19), which is why the section of this article refers to the consequences of its short validity in civil contracts. Initially, the deductive method was used for the development of this study, since it was based on the analysis of the abstraction of the contractual panorama in force during the pandemic, weaving on it a criticism based on the principles of contract law. In another turn, through the empirical method, a documentary research was also carried out, through analysis of the judges from the TJMT, to identify the different implications of the RJET in the practice of judicial review of contracts. In agreement, it was possible to realize that Law No. 14,010/2020 was not enough to prevent access to the Mato Grosso Judiciary to call for the revision of contracts due to the imbalance caused by the pandemic. It was also identified that the requirements reinforced by the transitional legislation on contractual review almost never had sheltered by the judge, since it has numerous tools that enable it to adapt the contractual terms to effect the values emanating from the Constitution and guarantee ingthe dignity of the parties involved, a hermeneutic exercise that proves more effective than the issue of its own and transitory legislation.
