This paper aims to address the procedural figure of new facts or newly discovered events, recognized in some continental Procedure Codes. In this context, we will examine certain historical sources that influenced its modern legislative reception, intending to understand the institution’s meaning, which is usually studied from an evidentiary perspective, with Chilean Civil Procedural Law serving as an example. In contrast to the above, our manuscript will assert that the new facts or newly discovered events, contained in article 321 of the Chilean Código de Procedimiento Civil, operate as a legislative mechanism aimed at incorporating new factual background, expanding the subject matter of the trial, and breaking the fiction of immutability of the process derived from the general principle of the doctrine of lis pendens, which justifies the application of the institution to the Chilean labour process.
