Has the case against
Caroline Farrow been brought up yet?
I'm no barrister but this approach seems at least colorable.
There's every chance that this could pass into law - but only in the sense that it falls under the umbrella of transphobic abuse/harassment/prejudice.
But there's a crucial point to remember:
In order for any court to convict, prosecutors would have to show convincingly that the alleged victim perceived prejudice on account of the wrong pronoun having been
deliberately used. The alleged victim would need to testify to the court as to the basis of that belief, and the court would then be required to adjudicate as to whether it (the court) believed the victim's perception to be honestly held.
To take a couple of examples:
Alleged Victim 1 (AV1) testifies that she was addressed with the wrong pronouns by Defendant 1 (D1), and that she perceived that this was a deliberate act by D1. Through AV1's examination and cross-examination, the court learns that this was only the second time that D1 had ever addressed her; the first time (when he had also used the wrong pronoun) was 18 months previously, and she hadn't directly corrected him at that time - but thought she remembered hearing that someone else had corrected him.
The court would (IMO) determine that AV1 was not honest in her perception that D1 had deliberately used the wrong pronoun, and therefore D1 had committed no crime.
Alleged Victim 2 (AV2) testifies that she was addressed with the wrong pronouns by Defendant 2 (D2), and that she perceived that this was a deliberate act by D2. Through AV2's examination and cross-examination, the court learns that D2 had used the wrong pronoun to address her - in the presence of others, who supplied affidavits to this effect - twice in the preceding week, and that AV2 had sent D2 an email (produced to the court) which she'd sent him on the day of the second incident, in which she told him which were the correct pronouns to use for her, and told him why it was important for her as a trans female that he should use the correct pronouns.
The court would (IMO) determine that AV2 was not honest in her perception that D2 had deliberately used the wrong pronoun, and that it was a function of deliberate transphobic abuse on the part of D2, and therefore D2 had indeed committed a crime.
