Janner has until Friday 14 August to go before the chief magistrate and whether this could happen in his home is up for consideration.
His appearance may be brief if necessary but it must happen. The court is then likely to pass the proceedings over to a crown court where a decision about a possible trial will be considered.
This is yet another case of justice delayed with all the obvious implications. If Janner is guilty of historical allegations of child and sex abuse why has it taken so long to bring any such charges before a U.K. court of law?
That delay does Janner and any victims or survivors of abuse if proved a disservice.
While it may seem cruel to drag Janner through the courts if he is guilty of such abuse it is cruel to try to ignore allegations.
In 2014 it was revealed that police had compiled a dossier holding more than 20 allegations against Janner; it was also revealed that a police officer was ordered not to search Janner's home.
In a statement Director of Public Prosecutions Alison Saunders said there was enough evidence to charge him with:
As we reported previously "In April the CPS, Crown Prosecution Service of the U.K., announced Lord Greville Janner, 86, a high-profile Labour peer, would not face sex abuse allegations dating back to the 1970's and 1980's due to his advanced dementia."
That decision was later overturned.
In late June 2015 the CPS website explained "In May, six of the complainants in this case requested a formal Right to Review, and at the DPP’s request, David Perry QC was instructed to provide advice to inform the CPS review of the decision."
The independent review, conducted by David Perry QC, "concluded that it was in the public interest to bring proceedings [against Janner] before a criminal court" - the Guardian - leading to a U Turn.
How a court case against Janner can go forward is the big question for now.
Updates as available
BBC News has the following to say about Lord Janner;
While it is an important inquiry and vital that justice is finally served the figures are staggering.
Was it so difficult to find a truly independent British person qualified to chair the inquiry? Did Home Secretary Theresa May set this pay deal?
But of course Goddard's pay is just the tip of the financial iceberg. With an estimated cost of £17.9m cost for one year:
Panel members will receive £565 a day, with staffing costs accounting for 41% of the overall budget. Costs relating to the set-up and running of offices across England and Wales make up 21% of the budget, while operational costs, such as safeguarding support, account for 17% of the budget.
UK Home Secretary Theresa May has approved the budget of £17.9m for 2015/16. Where do they get these figures from?
The inquiry was set to run from April 2015 until December 2018 but can be extended if necessary by mutual agreement.
The costs are staggering but what about the human cost of our failed justice system to the survivors of abuse?
