The subpoenas also requested the agencies hand over documents that Judge John M. Cleland had ruled were either subject to grand jury privilege or could only be viewed in his chambers. Among the documents Amendola sought were full and unredacted investigative files and psychological reports on Sandusky's accusers.
"This use of the subpoena power by the defendant is manifestly improper, lacks any basis whatsoever in the law ... and is a misappropriation of the authority of this honorable court," Senior Deputy Attorney General Joseph McGettigan wrote in court filings Friday.
He asked the court to rule the four subpoenas unenforceable and bar Amendola from issuing any more without the court's approval.
Amendola declined to comment on the prosecution's claims, citing a judicial gag order in the case, but denied he had done anything improper. He said he planned to file a detailed response next week.
In their filing Friday, prosecutors provided copies of subpoenas sent to the Pennsylvania State Police, the Pennsylvania Department of Labor and Industry, the Pennsylvania State University Police Department and the Central Mountain School District in Lock Haven, Pa., where one of Sandusky's accusers attended school.
Each orders the recipient to appear in court at a May 16 hearing ready to testify or to bring the documents requested to Amendola's office prior to that hearing.
McGettigan argued that Amendola purposefully presented that option, hoping the agencies would take the latter choice to avoid testifying. But the hearing referenced in the subpoenas is scheduled as a status conference in which no witness testimony will be taken, McGettigan said in his filings.
In at least three of the subpoenas, Amendola provided the alleged victims' names directly to the agencies - attaching a list in a sealed envelope in one case and printing one accusers' name directly in another. In the third, the attorney asked on one page that someone at the agency contact him directly for the purported victims' names, while listing them anyway on another page.
Each subpoena included a copy of Cleland's March 13 order that all the accusers' names be kept under court seal.
Prosecutors redacted the names in the copies of Amendola's subpoenas filed with their motion Friday.
Among the items sought from the state police were the unredacted investigative file on Sandusky, any prior reports on the purported victims as well as any documents handed over to former FBI director Louis Freeh, who is conducting an independent investigation into Penn State's knowledge of Sandusky's purported crimes.
Cleland has previously exempted certain state police records from the normal discovery process, citing an ongoing grand jury investigation.
From Central Mountain School District, Amendola requested school records including IQ testing, disciplinary reports, grades and psychological diagnoses for a boy prosecutors have identified only as "Victim 1." His complaints about Sandusky launched the attorney general's three-year grand jury probe in 2008.
The Penn State Police Department was asked to hand over the full 1998 police report conducted into allegations that Sandusky had inappropriately touched a 11-year-old while showering with him on campus.
While the case was closed without charges being filed, the findings included reports from two psychologists that Cleland has already said could only be reviewed in his chambers due to concerns of the purported victims' privacy.
The subpoena sent to the Department of Labor focused on worker's compensation claims for a number of employees whose names have been redacted in the copy provided by prosecutors Friday.
Sandusky has pleaded not guilty to 52 counts of child sexual abuse stemming from allegations he molested at least 10 boys over a 15 year period.
His trial is set to begin June 5.
