Does the Catholic Church need an independent tribunal?

The conviction of the Catholic bishop of Broome raises new questions about the ability of the church to investigate itself, especially in cases of abuse. A court found Christopher Saunders guilty of 12 counts of sexually abusing two young men and one count of rape. But it took eight years from when the allegations arose to get a criminal conviction. Now one of the world's leading experts on church law says Australia's bishops should establish an independent tribunal of senior jurists to act swiftly against abusive clergy.
