[Harry Potter] Harry Potter never discovers the entrance to the Chamber of Secrets and Tom Riddle’s diary regains a corporeal form. What is this version of Tom Riddle’s legal standing?

There would theoretically be a young Voldemort made from the life essence of Ginny and there would still be our Voldemort floating around in Albania. Does this new Tom Riddle, split from Voldemort from a young age, share all his memories, is he responsible for his older versions crimes, he certainly wouldn’t be as experienced or as powerful, and would potentially be relatively easy to capture. What happens if he is arrested and appears before the Wizengamot? Furthermore if he Avada Kadavras his way to avading capture what happens? Which aspect of Voldemort is the real one?

Also I understand that we may not want to prosecute Tom for Voldemort’s crimes but Tom did kill Ginny to regain his form. Is that a crime? Should children whose mothers die in childbirth be held accountable? I know a sentient diary is different than a child but I am looking for discussion, not judgement.

Tom Riddle's diary contains a soul fragment of Lord Voldemort, he is literally Lord Voldemort and would be treated just as Voldemort would be. The diary is aware of the crimes Voldemort committed, even after the soul was split, so there is no reason for him to be treated any differently.
