pruebas generadas por los usuarios, pruebas ciudadanas, Corte Penal Internacional, jueces, deepfakesResumen
Las pruebas registradas en dispositivos digitales personales, o «pruebas generadas por los usuarios» (UGE, por sus siglas en inglés), han influido profundamente en nuestra forma de conocer los crímenes internacionales. Se prevé que las UGE desempeñen un papel importante en futuros casos ante la Corte Penal Internacional (CPI), aunque hasta la fecha pocos juicios se han basado ampliamente en ellas. Esta investigación ofrece información importante sobre la forma en que los jueces de la CPI definen las UGE y perciben sus puntos fuertes y débiles, así como sobre la disposición de la Corte para adaptarse a juzgar en la era de la inteligencia artificial. Utilizando la teoría fundamentada para analizar las entrevistas con los jueces de la CPI, identificamos varios temas clave, entre ellos las preocupaciones sobre la importancia percibida y el posible sesgo de las fuentes de pruebas; los retos prácticos que plantea el empleo de la UGE; la carga que recae sobre las partes para garantizar la fiabilidad de las pruebas, para impugnar rigurosamente las pruebas de la parte contraria, y la importancia de preparar a los profesionales del derecho para hacer frente a los riesgos asociados a la desinformación y la información errónea.
