SYDNEY, Australia — An Australian court is to decide on Wednesday whether two planned trials for Cardinal George Pell, the senior Vatican official accused of sexual abuse, will be conducted in secret with the public barred from knowing what took place until the proceedings are over.

On Friday, prosecutors in the state of Victoria applied for a “super injunction” against news coverage of the separate trials. Legal experts described the application as an extreme move aimed at keeping juries in both cases from learning anything that might cause bias.

But a trial held behind closed doors would also limit accountability for the judge, jury and lawyers in the case.
