I found a link to a Barrister who has broken down the case, so far.
After the Levison Inquiry the Statute of Limitations was set at 6 yr. to file any legal actions, the results of the Inquiry were published /revealed in 2011 so anyone wanting to file legal action had until 2017, if I'm understanding it correctly. Here in the US, if someone tries to file a lawsuit after the SOL has expired, then he/she is up the creek, tough cookies, because he/she should have been aware of the time limits imposed.
Next Harry et al want the confidential info/results of the Inquiry made public. That's hitting sacred territory. If the Inquiry's confidentiality is breached, then in future investigations for any reason, people are not going to cooperate giving testimonies, providing highly confidential info for the reason that they're names may be exposed and the info they may have provided. There goes the reason for whistle blowing if the person is not protected for providing vital info.
I'm profoundly sorry the Baroness lost her child in a violent act, but waiting 30 yr.? No. Harry and William went through this in 2011 and with the Inquiry of their mother's death, he shouldn't have brought this up again it's beyond the SOL. Same with EJ and the rest. I love it that EJ didn't seem to have a problem with the DM when he allowed the paper to publish excerpts from his book for a nice sum. Hypocrite.
It's interesting they're going after the DM alone and not including the Murdoch Corp. where it all started...they know why. Fergie tried and got knocked out. In the US the complaints would have been dismissed.
