So where does it go from here. Into the rubbish bin?
The Commonwealth Director of Public Prosecutions says he cannot investigate information that Fair Work Australia has referred to him about the Health Services Union.
A Fair Work Australia inquiry found 181 breaches of rules and referred the matter to the Commonwealth prosecutor.
DPP Chris Craigie has released a statement saying Fair Work Australia's report was not a criminal investigation or a brief of evidence.
"The CDPP is not an investigation agency," he said.
"It does not have investigative powers and is not able to conduct a criminal investigation.
"In order for a matter to be assessed as to whether a prosecution should be commenced, a criminal investigation is conducted and a brief of evidence prepared and referred to the CDPP."
Mr Craigie said the letter he received from Fair Work made it clear that the industrial tribunal had not conducted a criminal investigation.
"The letter states that the report does not consider whether any person (or body) may have contravened a provision of the criminal law," he said.
"The material forwarded is not a brief of evidence.
"The CDPP will examine the material forwarded and consider what further action may need to be taken."
