Pope Francis on Friday issued sweeping new sex abuse legislation for Vatican personnel and diplomats that requires the immediate reporting of abuse allegations to Vatican prosecutors, a policy shift aimed at being a model for the Catholic Church worldwide.

The mandatory reporting provision, while limited in scope, marks the first time the Vatican has put into law requirements for Catholic officials to report allegations of sex crimes to police or face fines and possible jail time.

Francis also issued child protection guidelines for Vatican City State and its youth seminary, acting after the global sex abuse scandal exploded anew last year and The Associated Press reported that the headquarters of the Catholic Church had no policy to protect children from predator priests.

"I see this as something positive," Kamil Jarzembowski told the AP.

The law for the first time provides an explicit Vatican definition for "vulnerable people" who are entitled to the same protections as minors under church law. The Vatican amended its canon law covering sex abuse to include "vulnerable adults" in 2010, but never defined it.

According to the new Vatican definition, a vulnerable person is anyone who is sick or suffering from a physical or psychiatric deficiency, isn't able to exercise personal freedom even on occasion and has a limited capacity to understand or resist the crime, writes thepublicsradio.org
