Ipswich City Council is seeking a court's intervention to stop its elected officials being sacked by the Queensland government after corruption allegations claimed two mayors.
The besieged council on Tuesday lodged a request with the Brisbane Supreme Court to overturn a second notice issued by Local Government Minister Stirling Hinchliffe, which asked it to show why it should not be sacked.
Council is arguing Mr Hinchliffe does not have the jurisdiction to dismiss or suspend elected officials.
"The orders would restrain the minister from acting any further, and allow councillors to get on with the job of managing the city," council said in a statement on Wednesday.
"Council is of the view that ministerial powers must be exercised lawfully, and this move is to protect Queensland councils into the future by ensuring that, from the outset, these ministerial powers are appropriately applied."
Veteran councillor Paul Tully says the decision to take legal action was unanimous based on legal advice that it had a defendable case.
"Under the new legislation there is a particular procedure that (Mr Hinchliffe) needs to follow in respect of action either against the council or individual councillors," Mr Tully told AAP.
"Our argument is that he hasn't followed what's laid down ... and we are challenging the validity of the second notice which he served."
Mr Tully declined to detail how Mr Hinchliffe had breached process or what aspect of the notice was being challenged.
"We're taking it all the way because our legal advice is that we have a very strong and arguable case," he said.
Initial submissions will be heard before the Supreme Court on Thursday.
The Labor-affiliated council has until Friday to respond to "further matters", information the minister says is already public knowledge.
Liberal National Party Leader Deb Frecklington says a slow response from the state government was to blame for the saga.
Laws giving Mr Hinchliffe powers to sack or suspend councils were passed in state parliament last month following a Corruption and Crime Commission investigation which has seen 15 people with council links slapped with a total of 73 charges.
Administrators will be brought into to run the council if elected officials are sacked, with the next election due in March 2020.
