PQ vs Andreas Mueller & Others

Andreas Mueller is a respondent in an employment tribunal. He was alleged to have made gender critical statements and being a founding member of the Sex Equality and Equity Network in the Civil Service (SEEN CS).

A colleague is taking Mueller, a government department and the Arms-Length Body (ALB) where he works to an Employment Tribunal. The claimant is also seeking to shut down the SEEN CS staff network.

Status

The employment tribunal claim against Andreas Mueller ended in a settlement after nearly two years of litigation. The claimant, anonymised as PQ, a trans‑identifying man, requested to settle. Andreas Mueller stated on his crowdfunder that he believes it was because PQ and his lawyers were finally compelled to accept that the case against Andreas Mueller was unwinnable. It was settled on 20 March 2026, and PQ informed the employment tribunal of the withdrawal of his claim.

Andreas Mueller said he was pursued “because I expressed my protected belief that sex is binary, immutable, and sometimes matters — even in the workplace — and because I helped found the Sex Equality and Equity Network (SEEN) in Defra Group. The case began in April 2024. It was unjust, from start to finish.”

As part of the settlement, PQ requested confidentiality and a non-disparagement clause. Andreas Mueller refused both conditions. He said “accepting them would have prevented me from speaking freely and accurately about what I have been through — silencing me in the very way this case sought to silence me from the start. That would have compounded the injustice, not resolved it.” He also highlighted the wider pattern of targeting gender‑critical civil servants, the chilling effect on staff, and the lack of institutional support from his employer, the sponsoring department, and his union.

We did not report on the case as various hearings were held in private.
