An academic is preparing to take legal action after her lecture on sex and gender at the University of Bristol faced significant disruption from protesters. Prof Alice Sullivan, a University College London researcher, has written to both the university and the Office for Students (OfS) following the incident, arguing that her right to freedom of expression was compromised. She told the BBC that some potential attendees were intimidated and stayed away, suggesting that better planning could have prevented such disturbances.
“Everyone has a right to peaceful protest, but that must never amount to a heckler’s veto, which means shutting down other people’s right to speak,” Sullivan explained. She emphasised that the matter concerns not only her rights as a visiting speaker but also the university community’s ability to hold open discussions and attend lectures safely.
Her talk, which occurred in October, faced delays as protesters climbed walls, banged on windows, used megaphones, and triggered fire alarms. Sullivan said she was unable to remain to meet attendees afterwards and was later informed that some students and staff had felt too intimidated to attend. She noted that the university had 15 months to prepare and could have chosen a safer venue with fewer restrictions that inadvertently marginalised the lecture.
According to reporting by The Times, some of these restrictions reportedly included banning undergraduates from attending and holding the lecture at the Clifton campus, which was described as “extremely vulnerable to disruption from demonstration.” Sullivan stated she is “prepared to take legal action” to ensure that universities can host a broad range of viewpoints without intimidation.
Sullivan has previously criticised UK universities for not adequately protecting gender-critical academics from harassment or career-threatening restrictions on research. Her March 2025 review, commissioned by the Conservative government, highlighted concerns about academic freedom barriers, particularly for researchers studying sex and gender. She recommended that data on biological sex and gender identity should be collected as separate categories to preserve research integrity.
A University of Bristol spokesperson defended the institution, stating that the seminar proceeded safely and that measures were in place to protect both the speaker and attendees. “Although protesters caused unacceptable disruption, appropriate measures were in place to enable the event to continue,” they said. The spokesperson added that Sullivan had met with the vice-chancellor and expressed gratitude to the security team for their support. They refuted claims that the university failed to safeguard her free speech, insisting all restrictions were necessary for public safety.
The Office for Students declined to comment on the situation. The incident has reignited debates over the limits of protest on campuses and the responsibilities of universities to uphold academic freedom while ensuring safety. Critics argue that universities must balance the rights of demonstrators with the need to protect speakers and audience members from intimidation. Sullivan’s potential legal action could set a precedent for how institutions handle controversial topics and the security of academic events.
This episode highlights ongoing tensions in UK higher education over free speech, protest rights, and the protection of researchers tackling sensitive subjects. Academic voices argue that without adequate institutional safeguards, debates on sex, gender, and other contentious issues may be stifled, ultimately undermining scholarly inquiry and student engagement.
