TL;DR

Harrison Sharples, a 20-year-old medical student at St Andrews, was accused of generating his dissertation with AI. He had not. Clearing his name took two hearings and an appeal, cost him a semester of exams, and pushed his graduation from summer to December. The university says the appeal succeeded on procedural grounds alone.

What triggered it

Two human markers assessed the dissertation, on play therapy and anxiety in hospitalised children. One flagged it. Those notes, which the BBC has seen, cite a polished and uniform tone, grammar that was consistently flawless, sentence structure that never varied, and a paragraph pattern of claim, example, conclusion. Also listed: repetitive phrasing, thin critique, and heavy use of em dashes.

None of that is evidence of anything. It is a description of careful undergraduate prose, and every item on the list is something a diligent student might produce.

What it cost

At the first hearing the meeting link arrived five minutes after the start time. Sharples spent the half-hour session, already rattled, being asked to define medical terminology he had used. The allegation was upheld: mark capped at a bare pass, plus a permanent mark against him in the records the General Medical Council holds on future doctors.

That entry, not the grade, is why he appealed. The second hearing, in November, asked instead about how he wrote. This time the allegation fell. He received full marks.

The intervening months cost him his exams, which he deferred and sat mid-summer. “It was so big in my mind it didn’t allow me to think about anything else,” he said.

Looking forward

AI ethics adviser Sidrah Hassan told the BBC that detection tools remain unreliable with high error rates, and argued the fix is redesigning assessment rather than catching students out.

That is the pattern across the UK now. Denmark has moved teenagers to oral defence of their essays, Eisteddfod judges wrongly accused a Welsh learner’s novel, and here a medical student loses a year to marker suspicion. Note St Andrews’ careful wording: the appeal turned on the late link, not on whether the accusation was sound. The detection judgement itself was never formally overturned — the process that produced it simply had to be run again.
