I can’t find the text of the new law in 5 minutes of searching, but from looking at a variety of reports, it seems like this law removes loopholes that were being used to get parental permission for marriages involving children. I suspect they just wrote it this way because the bulk of the issue is older men marrying teenage girls, and that is a thing it does ban.
Even if he didn’t directly participate, did he witness it? Turn a blind eye? I hope future reporting is clear what it is and is not evidence of, but I also hope people ask the very reasonable questions that follow from what we do know now.
