The National Assembly’s petitions committee has referred the planning application for a giant waste incinerator in Splott to Environment Minister John Griffiths.
The committee wants him to look at the planning permission granted to Viridor and comment on whether the application process was carried out fairly and properly.
This follows a finding from the Public Services Ombudsman for Wales in March that Cardiff council had been guilty of “maladministration” after failing to consult some local residents about the plan.
The campaign group Cardiff Against the Incinerator (CATI) was pleased with the development, and its spokesman David Prosser said: “We have won another partial victory in our long battle against Viridor.
“But our test case proving failure to consult is just the tip of the iceberg.
“Local concerns about the impact of chimney emissions on children’s health, an extra 150-200 lorries a day using the incinerator and about the disposal of the toxic ash residue have been dismissed out of hand.”
CATI will also ask Mr Griffiths to consider whether what it called “grossly improper pressure” was placed on Cardiff council planning committee to grant planning permission in June 2010 when, it is alleged, the city’s planning officer told councillors that it would be “suicidal” not to do so.
The petitions committee decided it could not ask Mr Griffiths to call in the application for a full inquiry when planning permission had already been given.
“However, the Environment Minister can revoke planning permission under Section 3.10 of Planning Policy Wales where the original decision is found to be ‘grossly wrong’ and “damaging to the wider public interest”, Mr Prosser said.
Viridor is already preparing the site at Splott for construction work, which is due to begin in several weeks time.
