Isla Bryson is a convicted Scottish rapist whose 2023 legal case sparked a national crisis regarding the housing of transgender prisoners in female correctional facilities. Formerly known as Adam Graham, Bryson transitioned while awaiting trial for two rapes committed in 2016 and 2019. Her initial placement at Cornton Vale, an all-female prison, led to a public outcry, a rare intervention by then-First Minister Nicola Sturgeon, and a subsequent overhaul of the Scottish Prison Service (SPS) policies for transgender inmates. In early 2023, Bryson was sentenced to eight years in prison, with a further three years of supervision upon release.
In this comprehensive guide, you will learn about the details of the criminal case, the specific timeline of Bryson’s transition, and the political fallout that contributed to significant shifts in the Scottish Government’s approach to gender recognition. We examine the current 2026 status of prison regulations and the judicial rulings that have since defined the legal definition of “sex” in the United Kingdom. This article provides an authoritative, factual overview of a case that remains a flashpoint in global discussions on trans rights, women’s safety, and legislative safeguarding.
Criminal Convictions and Charges
Isla Bryson was convicted in January 2023 of raping two women, the first in Clydebank in 2016 and the second in Drumchapel in 2019. At the time of the offenses, Bryson was living as a man named Adam Graham and used online dating platforms to target vulnerable victims.
During the trial at the High Court in Glasgow, prosecutors described the attacks as predatory and “frenzied.” Despite Bryson’s claims that the encounters were consensual, a jury found her guilty on both counts, leading to her being placed on the sex offender register for life.
The Transition Timeline
Bryson began her transition from male to female in 2020, approximately one year after she was first charged with rape as Adam Graham. In court, she testified that she had identified as transgender since the age of four, though this claim was disputed by her estranged mother and wife.
At the time of her sentencing in February 2023, Bryson was taking hormones and seeking gender reassignment surgery. However, legal experts noted that she did not possess a Gender Recognition Certificate (GRC), which became a central point of debate during the subsequent political controversy.
The HMP Cornton Vale Controversy
Following her conviction in January 2023, Bryson was initially remanded to HMP Cornton Vale, Scotland’s only all-female prison. This decision was made by the Scottish Prison Service based on their existing policy, which allowed for the housing of prisoners according to their self-identified gender.
The placement lasted only a matter of days but caused a massive political scandal. Opponents argued that housing a convicted rapist in a female estate posed an unacceptable risk to female inmates, many of whom were themselves survivors of sexual violence.
Government Intervention and Review
First Minister Nicola Sturgeon eventually intervened, stating that Bryson would not serve her sentence in a women’s prison “either short-term or long-term.” Shortly thereafter, Bryson was moved to a male wing at HMP Edinburgh to await sentencing.
This case prompted the Scottish Government to order an “urgent lessons learned” review. By February 2023, the Scottish Prison Service announced a new policy: no transgender prisoner with a history of violence against women would be placed in a female facility without ministerial approval.
Impact on Gender Reform Legislation
The Bryson case coincided with the passage of the Gender Recognition Reform (Scotland) Bill, which aimed to make it easier for people to change their legal gender. Critics of the bill used the Bryson controversy to illustrate what they described as a lack of safeguarding for single-sex spaces.
Though the bill was passed by the Scottish Parliament, it was eventually blocked by the UK Government using Section 35 of the Scotland Act. The Bryson case is widely cited by political analysts as a key factor that eroded public support for the legislation at a critical moment.
Sentencing and Prison Life
On February 28, 2023, Lord Scott sentenced Isla Bryson to eight years in prison and an additional three years of supervision. The judge dismissed Bryson’s claims of vulnerability, stating that her crimes were “appalling” and had caused lasting trauma to her victims.
Since her transfer to the male estate, Bryson has reportedly complained of “transphobic abuse” from other inmates. In 2024 and 2025, several reports emerged regarding her continued stay in HMP Edinburgh, where she remains segregated from the general male population for her own safety.
Legal Definitions and 2026 Status
By early 2026, the legal landscape regarding gender in the UK has been further clarified by the Supreme Court. Rulings in 2025 established that for the purposes of the Equality Act, “sex” refers to biological sex rather than a person’s acquired gender.
These rulings have solidified the “biological sex” requirement for many single-sex services in Scotland, including prisons. Current 2026 regulations within the SPS reflect a “presumption of biological sex” for the initial placement of all prisoners pending high-level risk assessments.
Public Opinion and Media Coverage
The Isla Bryson case remains one of the most heavily covered criminal trials in recent Scottish history. It highlighted a deep divide in public opinion between those advocating for absolute trans rights and those campaigning for the protection of biological women’s spaces.
Media outlets across the political spectrum analyzed the case, with some focusing on the “institutional neglect” of women’s rights within the prison system. The fallout is often credited with playing a role in the eventual resignation of Nicola Sturgeon as First Minister in March 2023.
Practical Information and Planning
For legal researchers, students, or those following the legislative changes in Scotland, the following practical details are essential:
- Legal Record: Bryson’s crimes are recorded by Police Scotland as being committed by a man, as the offenses occurred prior to her transition.
- Prison Location: As of 2026, Bryson is housed in the male estate, typically at HMP Edinburgh, under high-security conditions.
- Accessing Records: High Court transcripts of the HM Advocate v Isla Bryson case can be accessed through the Scottish Courts and Tribunals Service.
- What to Expect: Legislative updates regarding the Gender Recognition Reform Act continue to be debated in the Scottish Parliament throughout 2026.
- Contacting Advocates: Organizations such as For Women Scotland and Scottish Trans provide ongoing commentary and resources regarding these policy shifts.

Final Thoughts
The case of Isla Bryson represents a watershed moment in Scottish judicial and political history, forcing a fundamental reconsideration of how the rights of transgender individuals are balanced against the safety of biological women in state custody. By February 2026, the legacy of this controversy is visible in the rigorous “biological sex” presumptions now embedded in the Scottish Prison Service (SPS) operational guidance. The swift removal of Bryson from the female estate in 2023 ended a specific crisis but initiated a multi-year legal battle, culminating in a landmark 2025 Supreme Court ruling that clarified the definition of “sex” as biological for the purposes of the Equality Act.
As of early 2026, the Scottish Government continues to defend its “individual risk assessment” model in the Court of Session against campaigners who argue for an absolute ban on trans-identified males in female prisons. While Bryson remains in the male estate, her case has permanently altered the legislative landscape, contributing to the stalling of gender recognition reforms and the resignation of high-level political figures. Ultimately, the Isla Bryson case serves as a permanent case study in the complexities of institutional safeguarding, ensuring that the protection of “ultra-vulnerable” populations remains at the forefront of Scottish penal policy.
