‘Thus: if someone uses the title “Professor” (when they are not legitimately one) and (1) does so dishonestly, (2) makes a false or misleading representation, (3) does so with the intent of gain (financial or other benefit) or to cause loss to someone else, then there is a possibility of a fraud offence.’
in a tribunal setting it would definitely be seen as a false representation to a claimant’s or respondent’s hearing because the title lends weight to their authority and would easily be argued in court that it reached the level of criminality.
A defence might be that she didn’t realise she couldn’t use it but in the environments within which she claims to operate that would be a stretch.
Gillian McKeith used the title Dr to misrepresent herself as a medical doctor but she did hold a PhD tho not from an accredited institution which means that you can’t use the title (institution needs to be accredited to issue such a degree) so there was a little bit of greyness that meant it might not be criminal representation.
I suspect that no one would want to charge Boyd though as it would bring the whole judiciary into disrepute.
