You have prepared for months, you know your subject inside out, and you sit down in the exam hall ready to succeed. But midway through the paper, you realize with a jolt of panic that your mobile phone is still in your pocket. Even if it is switched off and you haven't touched it, you may have already failed the exam.

This is the harsh reality of a concept called Strict Liability.

What is Strict Liability? 

In everyday life, your "intent" usually matters. If you walk out of a shop forgetting to pay for an item, you might be given the benefit of the doubt because you didn't intend to steal. However, under university exam regulations, the rules are often "black and white".

Strict liability means that the offence is committed simply because the act happened. If the rules say "no phones at the desk," and a phone is found at your desk, you are guilty of misconduct and that's the end of it. Your intention (or lack of it) has no impact on the finding of guilt.

Here's another example. Imagine you are driving down a road and pass a speed camera. If you are going 35mph in a 30mph zone, the camera flashes. In the eyes of the law, it does not matter if you didn't intend to speed, if you were distracted by a passenger, or if you simply didn't see the sign. The act of exceeding the limit is enough to be guilty of the offence.

The University's approach

The Rules at the majority of Universities are incredibly clear about this in their formal regulations. For example:

• University of Manchester: The policy states that a student found in possession of any unauthorised material once the exam has started will be subject to disciplinary action, regardless of whether there was intent to use the material. Usually, the minimum penalty is that your exam paper is cancelled and you are given a mark of zero.

• University of Leeds: Their definition of cheating explicitly includes "introducing unauthorised items into the examination room," including mobile phones and written notes. Whether you intended to bring the item, or have it at your desk, is irrelevant. Disobeying these regulations is treated as a very serious breach of academic integrity, and in many cases, students have been permanently expelled for these offences.

• University of Oxford: Oxford’s regulations prohibit taking any device on which files can be stored into the examination room. Proctors and examiners have the power to inspect any equipment you do have, and failing to comply with these strict instructions is a disciplinary offence.

• University of Exeter: Exeter’s regulations explicitly state that possession of unauthorised material is a strict liability offence. Therefore, their students can have no doubt about how they approach this.

Why "I Forgot" Isn't a Defence

Many students try to argue that they simply forgot the phone was in their pocket or that it was switched off and therefore couldn't provide an advantage. While this might be true, it is not a "defence" that will get the charges dropped. Because strict liability focuses on the physical act rather than your motive, an explanation of "I didn't mean to" or "I forgot it was in my pocket" cannot serve as a defence against the initial finding of guilt. At Cambridge, you are considered to have engaged in misconduct even if you were unaware the device was in your possession

While intention is irrelevant to whether the rules were broken, it is the primary factor when the university determines your penalty. If you can provide a consistent and honest account showing the breach was a genuine mistake rather than a planned attempt to cheat, the University may choose a more proportionate outcome, such as a formal warning, rather than expulsion.

Protect Your Degree

The only way to navigate these rules is to follow them perfectly. Check your pockets twice. Ensure all devices are switched fully off (not just on silent) and placed in your bag in the designated area well before the exam begins.
