Barría Vargas, Guillermo2020-10-032020-10-032020-10-032304-2494El medio de prueba pericial, antes era poco conocido o difundido; sin embargo, con los avances tecnológicos y las nuevas tendencias o campos en las cuales se desarrollan las relaciones personales, comerciales y jurídicas, han llevado a fortalecer su uso y se ha incorporado como el resto de la evidencia, siendo un medio de prueba más contundente, preciso y eficaz, logrando instruir en buena medida a los jueces de elementos que estos desconocen, aunque el tribunal tiene la facultad de apartarse del criterio expuesto en el dictamen pericial, siempre y cuando pueda fundamentar correctamente el punto de vista propio. En la actualidad, el perito dentro del Sistema Penal Acusatorio, es un medio de prueba imprescindible para la adecuada fundamentación de las alegaciones de los litigantes y la correcta resolución por parte del Juez.The means of expert evidence was previously little known or publicly spread, however, with the technological advances and new trends and fields in which personal, commercial and legal relationships develop, have led to the strengthening of its usage and it has been incorporated as the rest of the evidence as a more conclusive, precise and effective means of proof and thus it can bring light on the elements that the judges may not know or it may help to obtain an appreciation closer to the object of the opinion, although the court has the faculty to depart from the criterion stated in the expert opinion, as long as a point of view can be correctly substantiated. In present times, the legal expert within the Accusatory Criminal System is an essential means of proof for the adequate substantiation of the arguments of the litigants and the correct resolution by the Judge.application/pdfapplication/epub+ziptext/htmlapplication/xmlspaRevista CATHEDRA - 2019Courtjudgetestexpertaccusatory criminal systemTribunalJuezpruebaperitoSistema Penal AcusatorioArtículo de revista10.37594/cathedra.n11.355http://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2644-397Xhttps://doi.org/10.37594/cathedra.n11.355
