It does not apply when the victim accuses someone else.
Also, it does not apply unless there is an expectation of privacy. In a judicial committee, there are witnesses who know there is an investigation. There are multiple elders, instead being a one-on-one private confession. If the committee makes a finding, there will be a "... is no long one of Jehovah's Witnesses" announcement from the stage, or a "marking" local-needs talk.There is no reasonable expectation that what transpires in a judicial committee hearing will be kept private. (The same logic applies in the Los Angeles case 3mozzies referred to: if it was documented, then it was not a private matter between the penitent and confessor, and not protected by clerical privilege).
