Executive summary

Swiss reporting and legal commentary show that Article 261bis of the Swiss Criminal Code has been used to convict a man for a social‑media post that called non‑binary gender identities “mental illness,” after prosecutors treated the post as public denigration of LGBTQI people; he was fined CHF 500, ordered to pay CHF 800 in fees, and later opted for a 10‑day jail term rather than pay, according to multiple outlets [1] [2] [3]. The provision was broadened in 2020 to cover “sexual identities,” and prosecutors in this case argued the post publicly belittled a protected group and violated human dignity [4] [2].

1. Article 261bis: the legal weapon cited

Swiss prosecutions in these reports rely on Article 261bis of the Criminal Code, originally enacted to prohibit dissemination of ideas that denigrate on grounds such as race or religion and extended in 2020 to include protections tied to sexual orientation and — in some reporting — “sexual identities” [4] [2]. Media accounts and advocacy commentary repeatedly cite that the 2020 change broadened the statute’s reach, creating the legal basis for investigating and charging speech aimed at LGBT(Q)I communities [4] [2].

2. The contested facts of the Brünisholz case

The incident at the center of coverage began with a December 2022 Facebook reply to a politician’s post. The defendant wrote that skeletons show only men and women and called other gender identities “a mental illness,” language that complainants and prosecutors said constituted public incitement to hatred or denigration of LGBTQI people [2] [1]. Regional courts fined him CHF 500, added costs (reported as CHF 800 or CHF 600 in different sources), and affirmed the conviction on appeal; he subsequently announced he would serve a 10‑day sentence rather than pay [2] [3].

3. How Swiss authorities and courts characterized the statement

Reports say the Bernese judiciary found the comment “publicly belittled” LGBT(Q)I people and violated human dignity — the statutory standard prosecutors must show under Article 261bis — which justified criminal sanction in this instance [1] [2]. Coverage emphasizes the court viewed the wording and public forum (a social‑media reply) as aggravating factors that made the expression punishable under anti‑discrimination rules [1] [5].

4. Free‑speech pushback and counterarguments

A large portion of commentary frames the conviction as an attack on free expression and “biological facts,” with supporters arguing the statement was factual and that forensic anthropology shows sexual dimorphism in skeletons — therefore the prosecution suppresses scientific statement, not hate [2] [3]. Free‑speech groups and commentators described the ruling as “woke authoritarianism” and weaponisation of hate laws to police dissent on gender ideology [1] [3].

5. Governmental and political context cited by sources

Several outlets place the case amid broader Swiss debates: an e‑ID referendum and past parliamentary moves over whether to include gender identity explicitly in statutory protections, noting Switzerland’s legislature in earlier years debated but did not uniformly enshrine “gender identity” as a separate ground [2] [6]. Reporters link the timing and political environment to public unease about perceived state overreach [2] [7].

6. Disagreements in reporting and evidentiary limits

Sources disagree on precise legal wording and emphasis. Some describe the 2020 change as explicitly covering “sexual identities,” while others note historical parliamentary reluctance to add “gender identity” as a separate protected ground [4] [6]. Financial penalties and costs are reported with differing figures (CHF 800, CHF 600) across outlets [2] [5]. Available sources do not mention the trial record in detail, the court’s full written reasoning, or whether experts on forensic anthropology testified at trial; those facts are not found in current reporting [2] [3].

7. What this means for statements about biological sex under Swiss law

Based on reporting, statements about biological sex become criminal under Article 261bis when prosecutors and a court find that the expression publicly denigrates, belittles or incites hatred against a protected group (here, LGBTQI people) and thus violates human dignity; social‑media publication and language framing identities as “mental illness” were pivotal in the cited conviction [1] [2]. Competing perspectives exist: authorities treated the post as hate speech, while critics argue the same words asserted scientific fact and should remain protected — a disagreement reflected across the sources [1] [3].

8. Bottom line and open questions

The case shows Swiss courts can and have applied Article 261bis to social‑media comments that denigrate LGBTQI people; whether similar factual statements will be treated the same way depends on context, wording, and judicial assessment of whether human dignity was violated [2] [4]. Key documents — the court’s full reasoning and trial transcripts — are not provided in the cited coverage, which limits independent assessment of how Swiss law will apply in other cases (not found in current reporting).
