Pellicano's lawyers also assert that authorities have sought to hide Carradine's involvement in their investigation, producing only 13 reports written by Ornellas that mention Carradine during the time when she was in contact with the FBI agent.
Carradine could not be reached for comment, and an FBI spokeswoman said Ornellas could not speak about the criminal case because it was ongoing.
To date, authorities have downplayed Carradine's role in their prosecution of Pellicano. And in the latest court papers, prosecutors Saunders and Kevin Lally reject the notion that Pellicano's rights were violated, noting that most of Carradine's prison visits occurred before he was indicted.
Of the eight visits that occurred after that time, prosecutors say, five have already been documented by the FBI and do not include any information about the wiretapping alleged in the original indictment. Of the three visits that did not result in official FBI reports, the government says, one included a joint visit to Pellicano by his mother and Carradine.
In asserting that their client was wronged, Pellicano's attorneys cited a previously sealed court transcript in which prosecutor Saunders described Carradine as a "covert" source for the government on Jan. 6, 2006.
"Using concealed indictments, a hidden plea agreement, and closed court proceedings, the prosecution charged Mr. Pellicano with new offenses while creating a scenario for his longtime friend to gather information and trial strategy," Pellicano's attorneys alleged.
In doing so, the lawyers added, "the government knew and ignored the clear long-standing invocation of Mr. Pellicano's right to counsel."
Last year, Pellicano's defense made similar accusations that Carradine had improperly spied on him and that his right to proper legal representation had been violated.
The allegations went nowhere after authorities insisted that they did not assign Carradine to obtain information. Authorities also said they had reason to believe that Pellicano intended to represent himself on any new charges because of cash problems and potential conflicts involving other attorneys whom he had used in the past.
But the new allegations by Pellicano's attorneys contain more details than previously heard by the judge.
