Its application raises certain questions regarding the application of constitutional guarantees involving the right to defense. Through this documentary review, we analyze the challenges related to the application of this procedure, which is characterized by the principle of expeditiousness and the restriction of procedural phases. This research is developed within a qualitative, dogmatic, guarantor-based and constitutional approach that, through research, examined the limitations inherent to the procedural figure of the direct procedure, in relation to the reduction of time limits, phases of the process, and the effectiveness of technical or material defense. The results of the investigation showed that the procedure serves a valid legal purpose aligned with judicial effectiveness, but that it must be strictly applied in coordination with its exceptional criteria, so that procedural speed not prevails over the rights of the accused. Consequently, the guarantee interpretation must be harmonized with the effectiveness of the judicial system and the validity of due process.This article analyzed the legal implications, of the application of the direct procedure regulated in Article 640 of the Comprehensive Organic Criminal Code, conceived as an exceptional means for prosecuting flagrant crimes with certain legal exceptions.
