Not yet. The Inquiry is still taking evidence. They haven't taken evidence from the big-hitters yet, that begins in April.

In fact the Inquiry doesn't "hold humans accountable"; but they can compel witnesses, who testify under oath.

Gerald Barnes is the Fujitsu engineer who stated in the prosecution cases that Horizon was reliable ("robust"). His testimony to the Inquiry has been delayed, because on the morning he was supposed to testify, the Post Office "discovered" a million or so emails that they'd failed to disclose. So he'll be on the stand in April, along with the senior execs.

The Inquiry videos make quite pleasant watching; the lawyers and the judge are immaculately polite, there are no trick questions, and it's all about finding out what happened. I'm looking forward to seeing the senior execs on the stand.

The police are following the Inquiry; nobody's been charged, and my guess is they'll hold off on charging people until the Inquiry is over (that's part of the purpose of statutory inquiries). So the succession of Post Office Ministers that have overseen this disgrace will all be out of office by then.
