The Case That Changed Disclosure: What Liam Allan's Story Reveals About False Allegations

In December 2017, a rape trial at Croydon Crown Court collapsed after less than two hours of the complainant's evidence. It's one of the most significant cases in recent British legal history, not because of what it proved about the complainant, but because of what it exposed about the system meant to protect everyone involved. The defendant was Liam Allan, a criminology student at Greenwich University. He had spent close to two years on police bail, arrested and later charged, his degree and his future on hold, before the case against him fell apart in the space of a single afternoon.

The Allegation and the Investigation

Allan was accused of rape by a woman he had been in a relationship with. He denied it from the start and was arrested. What followed was the ordinary, grinding reality of a serious criminal investigation: months turning into a year, then into two, while the case moved through the system. He continued his studies at Greenwich University throughout, unable to talk about what was happening, living under an accusation that, if it stuck, would have ended his life as he knew it.

Throughout that period, police told the Crown Prosecution Service there were no "relevant downloads" from the complainant's phone. That single line in the disclosure process is the hinge the entire case turns on.

The Trial and the Collapse

The trial began in late November 2017. Days into proceedings, with the complainant partway through giving evidence, the defence finally received material that should have been disclosed long before: a full download of the complainant's phone. It ran to 58,000 text messages, delivered to the defence as roughly 2,500 sheets of paper, mid-trial, not before it.

Those messages told a story that directly contradicted the account given in court. Among them, messages sent by the complainant to friends in the days after the alleged assault, including one stating the encounter "wasn't against my will or anything." Other messages described her own stated sexual interests and fantasies, and one, sent about a month after the alleged offence, asked a different man if he was "going to take me into the park and rape me."

None of this had reached the defence. All of it had existed, sitting in a police file, for the entire two years Allan was under investigation.

The judge granted a short recess so the material could be properly reviewed. Within days, the Crown Prosecution Service formally dropped every charge. It happened just before Christmas 2017.

Allan described the moment in an interview afterward: "I was bracing myself for bad news because up until then it had all been bad news. For a second I was speechless and then I just started screaming."

Why This Case Changed the System

What happened next is the part of this story that matters beyond Allan himself. The scale of the failure was too significant to be treated as an isolated mistake. The Metropolitan Police and the Crown Prosecution Service's London South Area launched a joint review into how disclosure had failed so badly in this case. Its findings fed directly into the CPS's National Disclosure Improvement Plan, published in May 2018, a nationwide effort to overhaul how police and prosecutors handle evidence that could support a defendant's case.

That's the legacy of this case. Not a verdict on whether allegations should be believed less, but a documented, government-reviewed failure in how the system is supposed to work, and a set of reforms that exist directly because of it.

What This Case Does and Doesn't Show

I want to be precise about this, because it matters. The Liam Allan case is not evidence that most rape allegations are false. The overwhelming majority are not, and nothing here should be read as suggesting otherwise. What it demonstrates is something narrower and, in some ways, more disturbing: that when disclosure fails, when exculpatory evidence sits unreviewed in a file for two years, an innocent person can be dragged to the edge of a trial before anyone looks properly at what they already had.

Allan didn't lose two years because the system worked and got the wrong answer. He lost them because a process broke down and nobody caught it until a courtroom forced the issue. That distinction is the entire point of why this case still gets taught, studied, and referenced in disclosure training today.

If You're Living Through Something Like This

If you're facing a false allegation right now, the isolation is often as hard to deal with as the legal process itself. You can't talk about it the way you'd talk about any other crisis in your life, and the process moves slowly while your life doesn't wait for it. Nothing But The Truth was written for exactly this, what it actually feels like to live inside a false allegation while it's still unfolding, not after it's safely resolved.

You're not the first person this has happened to, and the record on cases like Allan's shows the system knows it has failed people this way before.
