The main objective of this article is to examine whether the right to appeal constitutes a fundamental right in civil proceedings. The method used was to verify current regulations; collecting arguments of doctrinal positions in this regard and analysing them in the light of case-law, mainly of the Inter-American Court of Human Rights and the Constitutional Court. For these purposes, 14 court rulings of the IACHR were collected, on which jurists rest their arguments. Likewise, a sweep of court rulings issued by the TC, from the year 2003 to July 2019, was carried out, increasing the review to a total of 5,963 judgments, out of which, 71 of them were related to the “right to appeal” specifically. The result has been that, in Chilean law, the right to appeal is not a fundamental right in civil proceedings.
