A recent ruling in San Antonio, Argentina, allowing a 10-year-old child to legally change gender has ignited a debate concerning the boundaries of judicial authority. Rosario Corvalán questions the decision made by the magistrate, as Argentina’s Gender Identity Law stipulates a minimum age of 14 for such modifications. Corvalán argues that judges are tasked with interpreting and applying existing laws, not establishing new ones independent of the legislature, to protect the separation of powers. The ruling raises concerns about potential overreach and conflicts with established legal frameworks. This case specifically challenges the established age requirement within the Gender Identity Law. The author emphasizes that altering established laws falls within the legislative branch’s purview, not the judiciary's. This decision calls into question the appropriate role of the courts in sensitive social issues.
