On Thursday, the case was adjourned for three weeks, giving lawyers time to apply to have the case moved to the Supreme Court, where Mr Singh will enter a formal plea and be sentenced.
Mr Singh was initially charged with four counts of culpable driving causing death in the days after the April 22 crash.
Police charged him with 33 extra offences in August. On Thursday, prosecutor Jason Ong withdrew 27 charges.
During the brief committal mention on Thursday, Mr Singh appeared via video link wearing a green jumper and with buzz-cut hair. He did not speak throughout the proceedings.
The case will next return to court on December 3.
Leading Senior Constable Lynette Taylor, Senior Constable Kevin King and constables Glen Humphris and Josh Prestney were killed in the Kew crash.
The four officers were in the emergency lane preparing to arrest Porsche driver Richard Pusey, who had allegedly been caught speeding.
In a statement released by his lawyer in the days after the crash, Mr Singh was said to be “genuinely sorry and saddened that four people have lost their lives as a result of the collision”.
“He is acutely aware of the impact upon the families, friends and work colleagues of those that lost their lives.”
In August, Frankston man Simiona Tuteru, 49, a manager at trucking company Connect Logistics, was arrested and charged with four counts of manslaughter in connection to the crash.
Police allege that Mr Tuteru, who co-ordinated drivers at Connect Logistics, knew before the crash that Mr Singh’s mental state had deteriorated due to a lack of sleep and alleged drug use.
The court heard in October that prosecutors were keen for the cases of Mr Singh and Mr Tuteru to be heard separately.
Mr Pusey was granted bail in October. He is to face a trial in the County Court on one charge of drug possession, plus reckless conduct endangering serious injury and reckless conduct endangering death, which relate to alleged speeding.
He will also face trial for the rare offence of outraging public decency. Mr Pusey has pleaded not guilty.
