The agenda for today's meeting includes a seven-page legal opinion which was given to the council ahead of the September 23 meeting.
The letter, from law firm Simpson Grierson, outlines several sections of the Local Government Act it says were breached or not complied with as a result of the September 12 meeting.
They included overstepping the role of the chief executive and opening the council up to a personal grievance from its newly-appointed Maori relationships manager by attempting to cut funding for his role.
The legal opinion is appended to a report for today's meeting in which Mr Power asks the council to approve payment of Simpson Grierson's bill which he says is "likely to approach $40,000".
His report says the legal advice was sought "to mitigate financial loss and damage to council's reputation" following "various unlawful and improper acts, and breaches of the councillor code of conduct, committed by Crs Joblin, Cairns, Flood and Bird in the lead up to, conduct of, and subsequent to, the extraordinary meeting called for 12 September".
Mr Power also wants the council to approve $30,000 of funding for training of councillors and the council's Maori standing committee "in relation to their understanding of their governance function and the proper processes to be adhered to in relation to" the Local Government Act.
Mr Power's report says Simpson Grierson have urged the council to "markedly improve councillor understanding of the governance and local government process".
But Ms Cairns said yesterday the four councillors Mr Power had pointed the finger at denied any wrong-doing and would raise their concerns at today's meeting.
"That's a really serious accusation the CEO has made," she said. "From our perspective the [Simpson Grierson] letter is very one-sided based on what the legal adviser has been told."
Mr Little said the four councillors had previously received governance and local government training, so they should have known their behaviour around the September 12 meeting was wrong.
At today's meeting councillors are also being asked to set up a new conduct review committee which would sit to consider breaches of the council's code of conduct.
Mr Little said it was likely the new committee would be called on to deal with issues related to the fallout from the September 12 meeting.
"Like anything in life you've got to have consequences. Any council would do the same," he said.
