An investigation by the Ombudsman found that former South Australian Minister Stephen Knoll committed misconduct by attempting to sack members of the Adelaide Cemeteries Authority board without authorisation.
Only the governor can dismiss members, but Mr Knoll tried to sack several members as well as its chair lawyer Ester Huxtable.
The findings were found last August but could not be released publicly until now, as Mr Knoll tried to challenge the decision in court but has now discontinued the case.
Mr Knoll resigned from cabinet shortly after the initial findings last year due to his involvement in another unrelated expenses scandal.
