Rome (CNN) Pope Francis issued new global rules Thursday for reporting sexual abuse in the Catholic Church, mandating for the first time that all dioceses set up systems for reporting abuse and cover-ups.

The new rules require all Catholic dioceses around the world to have a "public and accessible" system in place for reporting abuse by June 1, 2020.

The new norms cover internal Catholic Church procedure, not the issue of reporting abuse or cover-up to civil authorities, and represent a top-down imposition which must be followed by all dioceses.

Archbishop Charles Scicluna, Vatican's top investigator of sex abuse, told CNN that the new rules add a layer of accountability for church leaders.
