Details about the end of Peter's relationship with the ministry can be found on pg. 104 and 105 of Karl's book. The account is too long and involved to quote here, but essentially Peter was accused of operating outside the Way Tree structure, there were many written communications with Howard (who was made International Coordinator without Peter being told), Howard was nasty, Peter was very reasonable but in the end I think the core issue was HQ was not getting $ from Australia, etc. I very recently bought my copy of Karl's book so I know he's still offering it.
