Victoria Kolakowski made history this week when she became the first trans person to be sworn in as a trial judge in the US.

The trans campaigner, who has over 20 years of legal and judicial experience, took the oath of office at a special session of the Superior Court of California on Tuesday.

Her wife and parents were present at the ceremony.

Speaking before the ceremony, Ms Kolakowski told “It’s been very hard as a transgender person.

“We’re a community that’s chronically under- and unemployed and I’ve encountered that sort of discrimination in the past, but we’re making so much more progress now. In terms of my career, I think part of it is hard work and perseverance, and part of it is good luck.”

California state Senator Ellen Corbett introduced her as “a friend, a colleague, a trailblazer,” saying, “as we celebrate this new decade we mark our own start and our own first….We all know the tremendous hurdles that [she] and the transgender community have overcome.”

In the race, she beat deputy district attorney John Creighton with 51 to 48 per cent of the vote.
