Judge? Yes, sure, especially if you have access to relevant evidence. We can judge Hitler and Stalin, we have pretty conclusive evidence that they ordered terrible things.
Punishing someone is another matter, as is taking actions that might prejudge a trial. So, for example, it's now fine to say "Mason Greenwood is a rapist" (because he is), but while his trial was pending, saying that might have compromised his right to a fair trial.
