Whilst acknowledging that “there will be examples of judges who may have taken an approach that others wouldn’t approve of”, he said that “by and large what a judge is able to do is to identify the issues and then pursue what actually happened in a different way to the advocate”. He added: “I do not think it is impossible for a judge to probe and test an account of the vulnerable victim in a way that gets to the truth without undermining the rights of the defence.”

Speaking against the proposal on the Today programme, Sally O’Neill QC, a former chair of the Criminal Bar Association, questioned whether “judges would be so much better at cross-examining young witnesses than trained advocates”. She said it had been known “for some time” that the adversarial method of cross-examining young witnesses was not appropriate and was “almost non-existent”. “It’s a question of training,” she added.

Responding to Starmer’s proposals on BBC Radio 4’s World at One, Attorney General Dominic Grieve QC MP said that he welcomed the debate, but it raised profound issues about the right to a fair trial.  Penny Cooper, Chair of the Advocate’s Gateway, said: “[Our] guidance on questioning vulnerable witnesses is there for judges as well as advocates. However, in jury trials it is hard to see how this might work without compromising fairness to the defendant, many of whom are also vulnerable. To use the cricketing analogy, can judges be impartial umpires if they are also responsible for bowling at certain times?”
