Yes, I assume it is. The Royal Commission’s role is to identify factors in institutions that contributed to the sexual abuse of children. It found that easy forgiveness in confession encouraged recidivism. The Commission recognized that the Catholic Church is not the only religion that has this problem, but the evidence mainly came from Catholic case studies and those who treated such priests. A civil reporting law and a canonical prohibition of absolution can work together to discourage this use (or abuse) of the sacrament.  A civil reporting law is useless if the confessor doesn’t know who the penitent is. A canonical prohibition, if widely publicized, will be much more effective because the abuser will know that it is pointless going to confession if he knows that absolution will be refused until he hands himself in. That’s why a change in canon law is so important.
