Some interesting stuff
Just the costs for the legal action estimated at £40 million (I can see why Hugh Grant chose to settle)
Dodgy actions around the timeline as each claimed to have a revelation of "hacking" in 2016 - which just squeaked their cases in before the 6 year limit - even the judge has commented about the lack of documentation around 2016
The use of obscure website articles to create the "watershed" moment in 2016 - where the websites are own/controlled by those working as researchers for Harry's legal team on the case - possibly creating their own evidence
Paying "whistle-blowers" to give evidence
Strong reliance on evidence from private investigator Gavin Burrows who says his witness statement has been fabricated by Harry's legal team and that his signature was forged
