In Janner's case, the victims appealed the DPP's decision and a review overturned the decision. So there will be a Trial of Facts, not an ordinary trial, due to his dementia.
I'm very relieved to read this, because back in April several Mumsnet lawyers kept posting to insist that a Trial of Facts would be legally impossible in his case.
For Anyone and maybe other Mumsnetters too young to remember Janner in his heydey:
He was a very prominent MP for many years, finally retiring to the House of Lords.
There were allegations made against him by young boys while he was an MP, but he received glowing public support from other MPs and no charges were brought.
Earlier this year, he was facing 21 charges of offenses against young boys, but the DPP decided not to proceed, on the grounds of his dementia.
Also, the police announced then that when he was younger, they were ordered not to gather evidence against him.
Now the DPP's decision has apparently been overturned, the victims can hopefully have their cases heard in court.
Best wait for the official announcement this week though, just in case of funny handshakes ....
