Justice Wigney said the case would be given"absolute priority"by the courts as he would like to finalise the case"before we all retire".
The lawsuit has been dragged out for more than two and a half yearsafter applications for key documents have been denied.
Sally Dowling,SC,acting for the Australian Competition and Consumer Commission,told the court JPMorgan's internal and external legal team Gilbert and Tobin were refusing to hand over first account interview documents,claiming legal professional privilege.
Tim Game,SC,acting for ANZ,said his legal team had been given assurances those witnesses would be made available to him,and that access to those documents may shape the next steps of his defence,including a potential challenge of JPMorgan's indemnity.
"The JPMorgan witnesses are the heart of the prosecution’s testimonial case,"he said.
Justice Wigney granted leave for the ACCC to issue subpoenas to JPMorgan and the parties are scheduled to meet in court on February 22 next year with the view to start a trial"anytime in 2022".
