He and Bosland said the charges were aiding and abetting breaches of the suppression order by international media, breaching the suppression order, scandalising the court and sub judice contempt.
Anthony Loncaric, a spokesman for the Office of Public Prosecutions, declined to comment.
Two of Australia's largest media organisations, Nine and Australian Broadcasting Corp, confirmed that they had received letters. News Corp, another major media organisation that was criticised by a Pell lawyer for running a headline saying "CENSORED" following the conviction, declined to comment.
"We stand by all of our coverage and our actions in this matter," ABC said in a statement.
Boland said the number of journalists facing prosecution was unprecedented. "I've never seen a situation where such a huge number of people have been shown show-cause notices," Boland said. "Normally it's sent to one or two media outlets. But this is an extraordinary approach in extraordinary circumstances."
As soon as Pell was convicted on December 11 for oral rape and indecent acts involving two 13-year-old boys while he was archbishop of Melbourne in the 1990s, news began to spread around the world on social media. Some overseas-based media outlets and websites also began reporting the verdicts, although the sparsity of detail and factual errors suggested they had little if any help from professional journalists inside the court.
Melbourne's Herald Sun newspaper ran a black front page under the white headline "CENSORED" as the story was trending on Twitter.
Melbourne's the Age newspaper reported a "high-profile figure" had been convicted of a serious crime. Both mastheads have been put on notice by the state's chief prosecutor.
The Age, which is owned by Nine, reported that 30 journalists employed by Nine had been told in letters in February to show cause why they should not be charged. Authorities' responses to breaches of the suppression order — like the order itself — had been banned from publication until the order was lifted on Tuesday.
Two days after the verdict, trial judge Peter Kidd convened a court hearing with Judd to set the prosecutions in motion.
"A number of very important people in the media are facing, if found guilty, the prospect of imprisonment and indeed substantial imprisonment," Kidd said. Breaching a suppression order carries a maximum penalty of five years in prison.
The suppression order was designed to prevent the December conviction from influencing the jury in a trial that was to be held in April on allegations that he groped two boys in a swimming pool as a young priest in the 1970s. Those charges were dropped on Tuesday, so the suppression order was lifted.
But reporters still face the potential of charges for sub judice contempt, which alleges the reporting of the first trial interfered with the administration of justice in the second trial.
Scandalising the court is a form of contempt and aiding and abetting a breach of the suppression order recognises that helping the commission of a crime is itself a crime.
Contempt of court is a common law offence with no prescribed maximum penalty.
