However, councillors backed down from proposing a disciplinary investigation into the conduct of the council's chief executive David Henshaw.
'A report will be produced into the circumstances surrounding the release of the emails. This will go to councillor David Antrobus who will decide if it should go to a select committee to be investigated further,' a council spokesman told PRWeek.
Finnegan was suspended after a row between Henshaw and council leader Mike Storey. Henshaw later accused Finnegan and Storey of conspiring to oust him from the council.
