This book is an example of the transformative power of the judicial system and the importance of the constitutional control of the norms and acts of any public authority in order to protect the human rights of everyone. This work systematizes 50 of the most emblematic decisions that Mexico's Supreme Court has issued in recent years and that have positioned this court as a main actor in the construction of a more fair and equitable society. The decisions that have been selected stand out for their resolution of complex problems, their argumentative solidity and their contributions to democratic constitutionalism. It was sought that the chosen decisions have a high legal value and have been crucial to trace the path followed in the interpretation of certain human rights cases or related situations.
