The former Bishop of Lewes and Gloucester was jailed for 32 months yesterday for abusing several young men and misconduct in public office.
In court it emerged there was a chance to bring the 83-year-old to justice in the early 1990s which was missed.
After interventions from a member of the Royal Family, MPs and the Archbishop of Canterbury at the time, Lord Carey, Ball was let off with a caution.
In the wake of the scandal the Churches Child Protection Advisory Service reiterated its call for mandatory reporting.
Spokesman Simon Bass said: "Irrespective of who the person is, if you suspect abuse, you report that to your safeguarding officer who in turn will report that to the statutory agencies.
"Failure to do so would mean that those individuals would be held culpable for their failure to act."
Yesterday Lord Carey was forced to deny accusations of a cover up after suggestions he was a key player in the deal with the police that let Ball off on a caution.
Lord Carey admitted that he "dealt inadequately" with the allegations of abuse but said "allegations by some that my actions amounted to a cover-up or collusion with the abuser are wrong".
CCPAS told Premier that had mandatory reporting been law in the 1990s when allegations originally came to light this situation may not have happened.
"We're certainly pleased that the Archbishop of Canterbury Justin Welby has said there's going to be an independent review and I would hope that we're going to have lessons learned," added Simon Bass.
