Hearsay evidence is admissible in court. You need to serve a Hearsay Notice to the other party, setting out which bits of the evidence you are relying on is hearsay, and why the original witness can't be called to give direct evidence. The other party then has the opportunity to apply to the court for an order that the person who originally gave the evidence appears for cross examination.
That's what's being fought over currently. Harry & Co want to rely on the hearsay evidence of Mr Burrows, contained in his witness statement of 2021, and have presumably served a hearsay notice. They have to rely on hearsay, because in 2023, Burrows served a second witness statement saying his 2021 statement was untrue and he hadn't signed it, and he won't give evidence on their behalf directly. The DM want to cross examine Burrows and have applied to the court to do this.
However, Shereborne for the claimants wants the DM's application for cross examination to be delayed until they (the DM) give disclosure about payments they made to Burrows (allegedly) to cover his legal fees. Those payments are, on the face of it, for legal fees that the DM paid on behalf of Burrows, to allow him to engage an independent solicitor, and to make a further statement (dated 2025) refuting the original 2021 statement where he admitted unlawful information gathering on behalf of the DM. Sherborne obviously thinks the DM paid for more than just legal fees.
I remember it all blew up with this witness in 2023, when he first withdrew his 2021 statement. I can't believe it's still unresolved. Most of the claimants are relying on Burrows' 2021 statement (admitting UIG) which he's been saying is false for 2 years. What a clusterfuck!
