@AliceOlive I think this may be the sequence of events
PH's evidence was inconsistent - firstly he was unaware of (apart from one in 2006) incidences of phone hacking etc and therefore couldn't have brought the claim earlier. His evidence also says - he was made aware in 2010 of possible hacking. NGN argue this would put him into a timeline of needing to launch action prior to 2019 - which is when he did (possibly, I'm a bit confused!)
The secret agreement argument was advanced in a requested late amendment to his application The upshot of amendment was that due to a secret agreement (amusingly capitalised in the judgement!) it was agreed that Royal Household would not launch direct claims to avoid having to reveal sensitive info in court but at the conclusion of the MTVIL (mobile telephone voicemail interception litigation) and the Royal Household would engage with NGN and apology/settlement reached.
The challenge facing PH as espoused by Judge, is that his recollection of the Secret Agreement wasn't present in 2021 (March and later in November) when he filed his 'Reply' but he recalled it when reviewing correspondence (internal Royal Household staff/NGN) when Sally Osman was communicating with NGN expressing a desire to get everything sorted pre PH/MM wedding with references to having to go legal if not sorted informally (am paraphrasing!). This review of comms & recollection of Secret Agreement apparently took place as PH was preparing his evidence for trial in 2023 and therefore led to late application to amend the contradictory elements of this previous statements.
The 2017/2018 correspondence (allowed by HMTQE2) between Royal Household & NGN also suggests that the 'Secret Agreement' to wait until end of MTVIL was no longer in play as Sally Osman is suggesting legal alternatives and MTVIL not yet concluded. PH argued that the palace had kept him out of the loop about the Secret Agreement but the Judge decided this was not consistent with PH's evidence
PH also claimed that PW had a huge settlement with NGN and NGN hadn't sought strike out on terms of out of time - PH's argument was that this was evidence of the Secret Agreement in action. The Judge's view was that this settlement wasn't evidence of a 2012 Secret Agreement but that NGN didnt want to get embroiled in litigation.
PH's legal team argued that the offer of a settlement from NGN to PH in 2019 was evidence of Secret Agreement - Judge disagrees and says it is the same scenario as PW
Almost at end of his judgement, Judge writes
- For all the reasons that I have given, I am unable to conclude that there is a sufficiently plausible evidential basis for the new case based on the secret agreement to justify the grant of permission to amend at a late stage of the proceedings. The lack of credibility arises from: the unexplained lateness of the plea, linked to the nature of the estoppel plea; the improbability of a secret agreement being made in the particular terms pleaded; the inconsistency with the Duke’s currently pleaded case, which is twice supported by statements of truth, and with his evidence in other proceedings, supported by a statement of truth; the absence of any explanation for the new factual case being raised; and the absence of any other witness or documentary evidence to support it.
obviously am not a lawyer so all faults in my reading of the judgement are mine alone and happy to be corrected!
(The to-ing and fro-ing between different statements, submissions, amendments and timeline jumps between 2021 and 2023 and then 2006 or 2012 make reading the judgement akin to a legal take on Inception!!)
