Sandra Paul discusses the complexities and challenges of dealing with allegations of sexual misconduct in the workplace

Latest blogs & news

Preparing for changes to non-disclosure agreements from 1 October 2025

In June the Ministry of Justice announced new legislation under the Victims and Prisoners Act 2024 which affects NDAs and confidentiality clauses.* Related guidance, published at the beginning of June, sets out the impact of this legislation on the enforceability of such agreements.

OfS Condition E6: a first step towards a unified approach to harassment and sexual misconduct, but does it go far enough?

In July 2024 the Office for Students (OfS) published guidance on a new condition of registration dealing specifically with harassment and sexual misconduct. That condition, ‘E6’, comes into force on 1 August 2025. As such, universities and colleges have had a year to ensure they comply.

Adolescence: The ordinary family’s worst nightmare

As we await the release of the Netflix series Adolescence this evening by award winning writer Jack Thorne, I am interested to see how the series will deal with very real, yet often publicly unheard problems of how our criminal justice system, in particular the police, manage children who are alleged to have committed serious offences.

Sir Brian Leveson’s review of the courts

Whatever its cause, a backlog of over 73,000 Crown court cases is not acceptable. Delays for complainants, defendants and witnesses all impede justice. In the third quarter of 2024, the Crown court received over 31,683 new cases and disposed of 29,502. The passage of time will not solve the problem. Change is inevitable. 

Tackling the regulation of sexually explicit deepfakes

Artificial intelligence, and its use on social media, is making it continuously harder to distinguish between real and fake information online. Although fact checking is often required when considering written or spoken words, with the advent of so-called “deepfakes”, we now also need to fact check some of the images or videos we see online.

I am the victim of sextortion - what should I do?

Sextortion is a form of blackmail where victims receive threats that intimate images of them will be shared or distributed unless they meet the blackmailer’s demands to pay money (or other financial demands).   Law enforcement agencies have reported an epidemic of such cases with global figures “more than doubling” in 2023.    This reported increase is reflected in the number of clients seeking our advice on how to deal with this particularly distressing form of criminality.

Disclosure under the microscope

Mr Jonathan Fisher KC’s ongoing Independent Review of Disclosure & Fraud Offences recently published its “Preliminary Findings & Direction of Travel” report for part one of the review, which relates to the criminal disclosure regime. The report can be found here

New sentencing guidelines are now in force

On 1 April 2024, a number of new and amended sentencing guidelines came into effect, following publication of the results of a consultation by the Sentencing Council which ran during Autumn 2023.

First cyber-flashing conviction under the Online Safety Act 2023

In a landmark case, Nicholas Hawkes, from Basildon, Essex, has become the first person to be convicted and imprisoned in England and Wales for the criminal offence of cyber-flashing. This historic verdict marks a significant moment in the life of the Online Safety Act 2023 (OSA), which aims to combat digital harassment and safeguard online communities.

Policing the metaverse: the reality of virtual sexual offences

The police are undertaking the first reported investigation into a “virtual rape”, which is said to have taken place in the metaverse. This case brings to the forefront a number of questions around the adequacy of the UK’s current legislation surrounding sexual offences, and whether it can cater to behaviours taking place in the metaverse.

Expansion of the disregards and pardons scheme for historic same-sex sexual activity convictions

In a long-overdue announcement by the Home Office, women who were in the past unjustly convicted of same-sex consensual sexual activity will be able to apply for their convictions to be disregarded or pardoned for the first time. This is a significant step forward for queer rights in the UK.

Does anyone care about us?

Research reveals overwhelmingly negative experiences of the care system for victims and perpetrators of youth violence.

In March 2023, His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) commissioned research on the lived experiences of those who have committed – or experienced – serious youth violence. The findings were published alongside HMICFRS’s report into the policing of these issues and as cross-disciplinary calls increase for a rethink of how  serious youth violence is tackled. In a follow-up to his previous blog, Paul Egunjobi looks at the findings.

The impact and future of violence reduction units

On 8th March 2023, His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) published a report examining how well the police tackle serious youth violence. We look at the report and one of the issues it has highlighted: how Violence Reduction Units (VRUs) are used, and how effectively the police work with VRUs and other partner organisations.

In the wrong place at the wrong time

Long delays are an all-too familiar part of the criminal justice system. As highlighted in the recent case of BH v Norwich Youth Court, those delays can have a significant impact on young people, particularly when a defendant turns 18 during the long process. An imminent change in the law may improve the situation but there are wider issues to be solved, too. Partner Sandra Paul and paralegal Emma McGrath look at the issues.

Joint police and FCA action underlines law enforcement attention on cryptoasset activity

Amid increased focus on the regulation of cryptoassets in the UK, law enforcement agencies have carried out unprecedented raids targeting illegally-operated cryptocurrency ATMs.

Consent – a missed opportunity for an important discussion

Channel 4’s, Consent, appeared to be a show with something to say; a show that would draw attention to the complexity of sexual allegations involving school aged children as well as the emotional trauma for all caught in its wake.

The Online Safety Bill: What do the latest updates mean for companies and senior managers?

The Online Safety Bill hit the headlines last week, following its third and final reading in the House of Commons on 17 January 2023. Since its early stages the Bill has provoked an ongoing debate between social media safety groups, who call for the law to do more to protect children, and civil liberties campaigners, who argue that the proposed legislation impinges on the freedom of speech. The latest proposed amendment would make senior managers criminally liable for platforms’ persistent failure to protect children online. Magda Zima considers the potentially wide-ranging impact of this amendment on both companies and senior individuals.

A new police approach is needed to tackle overwhelming delays to digital forensics

A damning report published by His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) has found police forces to be “overwhelmed and ineffective” in relation to digital forensics. The HMICFRS found that there were more than 25,000 devices waiting to be examined – and this is without taking into account all the devices already in the system.

My child has a conviction for a sexual offence, what happens next? Notification requirements and ancillary orders for children convicted of a sexual offence

This blog follows the virtual launch of the Youth Justice Legal Centre Legal Guide on children facing sexual offences. During this event, Maeve Keenan discussed Kingsley Napley's contribution to the report, including recommendations on how to appropriately handle these complex cases and protect the child's welfare.

 

 

Help! The police are arresting my child …

It’s the knock on the door that parent fear, or is it just me? Thankfully, the Courts have provided some valuable guidance about this nightmare scenario.

There are many reasons the police may want to speak to your child, but few occasions where the reason might be urgent enough to justify an unannounced visit and an arrest.
