The fate of controversial plans for controlled parking zones in two areas of Bristol are to be discussed at a council scrutiny meeting on 5 January.
A decision by Bristol City Council's cabinet in November giving the go-ahead was "called-in" by two members.
This could mean the matter is referred back to cabinet for further discussion, debated by the full council or that the decision stands.
The average annual charge would be about £200 for a two-car family.
The decision on 27 November, if implemented, would mean motorists in the Brandon Hill and Kingsdown areas of Bristol would have parking restrictions to keep commuters away from streets in the area.
But the cabinet's decision was "called-in" at the request of Conservative councillors Richard Eddy and Peter Abraham.
They argued the public consultation which took place during July was "shambolic from the outset." with it taking place while many residents were on holiday.
The pair also believed the council's executive "failed to take into account" views from professionals over the "detrimental effects" on neighbourhoods lying directly outside the proposed pilot areas.
They also said ward councillors and stakeholders were denied opportunities to make comments on the "deeply flawed" questionnaire distributed to households.
Campaigners against the proposals said most residents and businesses did not want to pay for parking permits.
Speaking in November they believed the residents' parking scheme was "just another tax" for local people to pay.
"And for residents there is no guarantee they'll get a space outside their house - they'll be competing with businesses and other residents in the scheme from the area," said Bernard Cooke from the Keep Parking Free campaign group
Then councillor Mark Bradshaw, Executive Member for Sustainable Development, said the scheme was in response to complaints from local people.
"We are putting residents and businesses concerns at the heart of these proposals," he said.
The Kingsdown parking zone would operate from 0900 to 1700 Monday to Friday.
The Brandon Hill area would have restrictions running from 0800 to 2100, Monday to Saturday.
