Redactions are normally agreed by both sides. Where there's a dispute, the panel would decide, either at a preliminary meeting before the main hearing or during the hearing itself.
For clarity, because I've been called on it, by 'both sides' I mean 'both barristers'. I can't imagine the witnesses would have been asked.
As a general principle, the regulators aren't places for the victims of a clinician to seek redress. That's what the civil courts are for - for people to sue and seek damages. They're there to protect the wider public and set standards for doctors, and to police breaches of those standards.
The victims are really just there as witnesses, which I appreciate must feel monumentally shit, but is the way the system works.
