A Sydney council is "confident" it can stop the NSW government demolishing and rebuilding Allianz Stadium at Moore Park after a judge agreed to expedite a court hearing.
Waverley Council is challenging the government's $730 million proposal in the Land and Environment Court on the basis that Planning Minister Anthony Roberts approved the new stadium without first determining it would exhibit "design excellence".
The council on Wednesday was granted an expedited hearing to be held concurrently with a separate case brought by Local Democracy Matters.
The community group launched its legal case against the government earlier in February also claiming the government botched the approval process.
Waverley's Labor mayor John Wakefield says the council wants the court to declare the minister's consent "invalid and of no effect".
"I'm confident we have a very solid case and we are defending the principles of law, the process of law and the interests of the community," Mr Wakefield told AAP on Thursday.
The council has named the SCG Trust, Infrastructure NSW and developer Lendlease as respondents along with the minister.
It is believed Lendlease has agreed not to undertake any hard demolition until after the three-day hearing which is scheduled to commence on February 20.
