The police response to an ex-officer's allegedly transphobic tweets was unlawful, the High Court has ruled. Harry Miller was visited by Humberside Police at work in January last year after a complaint about his tweets. He was told he had not committed a crime, but it would be recorded as a non-crime "hate incident". The court found the force's actions were a "disproportionate interference" with his right to freedom of expression. Officers visited Mr Miller's workplace and then spoke with him on the phone, and he was left with the impression "that he might be prosecuted if he continued to tweet", according to a judge. Speaking after the ruling, Mr Miller, from Lincolnshire, said: "This is a watershed moment for liberty - the police were wrong to visit my workplace, wrong to 'check my thinking'." His solicitor Paul Conrathe added: "It is a strong warning to local police forces not to interfere with people's free speech rights on matters of significant controversy." 'Orwellian society' Mr Justice Julian Knowles said the effect of police turning up at Mr Miller's place of work "because of his political opinions must not be underestimated". He added: "To do so would be to undervalue a cardinal democratic freedom. "In this country we have never had a Cheka, a Gestapo or a Stasi. We have never lived in an Orwellian society." Responding to the ruling, Helen Belcher, who co-founded Trans Media Watch, said: "I think trans people will be worried it could become open season on us because the court didn't really define what the threshold for acceptable speech was. "I think it will reinforce an opinion that courts don't understand trans lives and aren't there to protect trans people." Mr Miller, 54, also launched a wider challenge against the lawfulness of College of Policing guidelines on hate crimes, which was rejected. Mr Justice Knowles ruled they "serve legitimate purposes and [are] not disproportionate". The guidelines define a hate incident as "any non-crime incident which is perceived, by the victim or any other person, to be motivated by a hostility or prejudice against a person who is transgender or perceived to be transgender".
