A Sydney council will take the NSW government to court over its $730 million plan to demolish Allianz Stadium and build a new one in its place at Moore Park.

Waverley Council on Thursday night voted to launch legal action in the Land and Environment Court on the basis the planning minister approved the new stadium without first determining it would exhibit “design excellence” as required under the Sydney Local Environment Plan.

Waverley’s Labor mayor John Wakefield said Anthony Roberts has failed to provide any legal assurance the government had followed due process.

“We have given him plenty of opportunities to respond to us and provide us with material to refute our barrister’s claims,” Mr Wakefield told AAP on Friday.

Mr Wakefield said the council would be lodging paperwork with the court early next week.

Community group Local Democracy Matters separately launched legal proceedings in the Land and Environment Court this week claiming the government botched the approval process ahead of hard demolition works which are now scheduled to begin in late February.

Justice Terry Sheahan on Wednesday agreed to expedite the case with a three-day hearing set down starting on February 20.

It’s likely the two matters will be heard concurrentl
