Former treasury official David Eastman's case for compensation, after he was wrongfully forced to spend 19 years behind bars, is set to be heard later this year.
The ACT Supreme Court has listed the matter for final trial on September 30, with further mention and directions expected on April 5.
The ACT government has yet to respond to a request for an "act of grace" payment.
Mr Eastman was found not guilty last year of murdering federal police assistant commissioner Colin Winchester in 1989.
It was the second time Mr Eastman was hauled before the court over the high-profile killing.
Mr Eastman pleaded not guilty to the murder in 1993 but was sentenced to life in jail in 1995.
His conviction was quashed in 2014 over concerns about the original evidence, and a new trial took place last year, where he was cleared of the crime.
Mr Eastman filed a wrongful imprisonment claim against the ACT government in 2015, which was on hold until the November verdict.
The compensation claim is widely expected to net the 73-year-old millions of dollars.
The case centres on a section of the ACT Human Rights Act which deals with unlawful imprisonment.
In 2009, the WA government issued a $3.25 million ex-gratia payment after Andrew Mallard spent 12 years in jail for a wrongful murder conviction.
