Spanish Abstract: El presente articulo analiza, tanto desde una perspectiva normativa como empirica, el sistema de expulsion y, mas en concreto, la progresiva consolidacion de la expulsion judicial, creada por la Ley 20.603. A estos efectos, el texto toma en consideracion un marco analitico que ha tenido gran impacto academico internacional en los ultimos anos, la denominada tesis de la “crimigracion”. Desde este punto de vista, el trabajo se centra en ver si, al igual que ha sucedido en una pluralidad de ordenamientos internacionales, en Chile se ha verificado una creciente prioridad de las expulsiones vinculadas a la comision de delitos y, por lo tanto, al sistema penal. Junto a ello, el articulo concluye con una indagacion sobre el sentido y fundamento de la expulsion judicial en nuestro ordenamiento, asi como con una reflexion sobre las diversas racionalidades de control que operan en este ambito de las politicas penales. English Abstract: This paper examines, from both a legal perspective and an empirical viewpoint, the Chilean deportation system, and more precisely the gradual consolidation of criminal law deportations, which were enacted by the Law No. 20,603. For these purposes, the analysis draws upon a theoretical framework that gained significant academic traction in the last years, i.e. the so-called ‘crimmigration’ thesis. From this standpoint, this paper is largely focused on exploring whether, in line with what has occurred in a number of jurisdictions, also in the Chilean criminal justice system crime-based and criminal law deportations have been given increasing preference in the recent past. In addition, the article concludes by delving into both the meaning and grounds of criminal law deportations and the variety of law enforcement rationales which are at play in this field of penal policies.
