MILAN, June 4 (Reuters) - Bishops found to be "negligent" when dealing with priests accused of sexual abuse of minors will be investigated and could be removed from office, a papal decree said on Saturday.
Pope Francis in 2014 established a Vatican commission intended to establish best practices to root out abuse in parishes.
The Roman Catholic Church has been rocked for the past 15 years by scandals over priests who sexually abused children and were transferred from parish to parish instead of being turned over to authorities and being defrocked.
