The intention is to demonstrate the incompatibility between the procedural rule contained in Article 300, paragraph 3?, of the Code of Civil Procedure, and the civil lawsuit?s objective of serving as a tool capable of safeguarding legal rights adequately, effectively and timely. Based on this premise, this study argues both for the flexibility of the procedural rule in light of the particularities of the case and the need for the judge to favor the one party?s likelihood of success on the merits in detriment of the opposing party?s non-likelihood of success on the merits. In order to assess the level of likelihood necessary to grant the preliminary injunction, the judge must balance the conflicting interests and values as well as the extension of possible harms to the rights of the parties, applying, to further such evaluation, the normative postulates, principally the postulate of proportionality. / O presente trabalho tem o prop?sito de analisar o modo como o sistema jurisdicional brasileiro busca tutelar aquelas situa??es em que h? a necessidade de satisfa??o imediata do direito, mas que a decis?o que antecipa a tutela ? capaz de produzir efeitos irrevers?veis. Busca-se demonstrar a incompatibilidade da regra processual prevista no artigo 300, ? 3?, do C?digo de Processo Civil com a finalidade do processo de servir como instrumento apto a prestar tutela adequada, efetiva e tempestiva aos direitos. Partindo-se dessa premissa, defende-se a possibilidade de supera??o da regra processual em raz?o das circunst?ncias evidenciadas no caso concreto e a necessidade de o julgador privilegiar o direito prov?vel em detrimento do improv?vel, devendo levar em conta, para a verifica??o do grau de probabilidade exigido, os bens e valores colidentes e a extens?o dos preju?zos aos direitos de ambas as partes, utilizando-se, para tanto, dos postulados normativos, especialmente do postulado da proporcionalidade.
