This paper aims to exhibit three issues that have risen in Consumer Law as a result of the enforcement of Law No. 19,496 by our Courts of Justice. First, the enforcement of the protective statute by micro and small companies against their suppliers under the terms of Law No. 20,416. Second, the close dependency or autonomy between infringement liability and compensation, particularly under the hypotheses by which legal warranty operates. Lastly, the expiration period that characterizes the legal warranty as opposed to the general statute of limitations periods set forth in Article 26 of Law No. 19,496.
