Criminal conduct

Criminal conduct

For a person to be found guilty of a criminal offence it must be shown that they:

•
acted in a particular way
•
failed to act in a particular way (omission), or
•
brought about a state of affairs.

The criminal conduct or criminal act of an offence is also known as the actus reus and this behavioural element is the essential characteristic of any offence.

Criminal act

The mental element of an offence is what a defendant must have had, while the criminal act is done or was failed to be done. When proving the required criminal act it must be shown that:

•
the defendant's conduct was voluntary, and
•
it occurred while they still had the requisite mental element

Other than in a few specific instances where an omission will suffice, the prosecution must show that the defendant acted voluntarily by operation of their own free will.

Generally, it must also be shown that the defendant had the required mental element or mens rea at the time of the carrying out of the criminal act.

HMPPS announces changes to official prison video calls for legal representatives guidance

The HM Prison and Probation Service (HMPPS) has published an updated guidance on changes to prison rules concerning official video call meetings, set to take effect from 20 January 2025. The update allows prison staff to intermittently observe video call participants from a control room screen without seeking prior consent, aligning the procedure with in-person visits. This visual-only monitoring aims to ensure call security without compromising privacy. Legal representatives and clients retain the option to refuse control room observation, in which case the call can proceed with physical area patrols, or they may opt for an in-person visit instead.

SFO secures first Unexplained Wealth Order in £100m fraud case

The Serious Fraud Office (SFO) has successfully obtained its inaugural Unexplained Wealth Order (UWO) at the High Court, targeting a £1.5m Lake District property owned by Claire Schools, ex-wife of convicted solicitor Timothy Schools. The property is suspected to have been purchased with proceeds from a £100m fraud. The SFO has frozen the asset and has ordered Claire Schools to provide information on its acquisition within 28 days. This landmark case follows a recent £1m confiscation from Timothy Schools and marks the SFO's first use of the UWO tool since its introduction in 2017, making it the second UK law enforcement agency to employ this investigative measure.
