What is Consent in Law?

Why education matters in preventing Sexual Offences

It was reported by BBC News that nearly 19,000 criminal cases remain outstanding in London, placing significant pressure on the criminal justice system. While much of the focus is understandably on the impact these delays have on victims of sexual assault and domestic abuse, the backlog also affects those who have been wrongly accused, leaving individuals in prolonged legal uncertainty.

There is no single solution that will eliminate the backlog overnight. However, education around consent plays a role in helping to reduce the number of sexual offence cases entering the system. In some cases, allegations arise in circumstances where consent is disputed. While a lack of understanding of consent is not a defence in law, improved education helps individuals better recognise boundaries and make lawful choices.

In England, educating young people — particularly boys — about consent is now mandatory as part of the statutory Relationships, Sex and Health Education (RSHE) curriculum. This education is widely recognised as essential in tackling sexual violence, sexual abuse, and harassment, especially among young people.

What is consent?

In England and Wales, police recorded over 209,000 sexual offences in a single year, although the true figure is believed to be far higher due to underreporting. Rape Crisis reports that 2 in 5 rapes against women are committed by a current or former partner, and 6 out of 7 are carried out by someone the victim knows. These statistics highlight why clear consent education is crucial at every level of society.

Consent means freely agreeing to something. In a sexual context, consent means freely and enthusiastically agreeing to take part in sexual activity.

From a legal perspective, consent is defined by the Sexual Offences Act 2003. Under the Act, a person consents if they agree by choice and have the freedom and capacity to make that choice.

This definition is central to many sexual offence investigations and prosecutions.

Key points about consent

Consent must be given freely, without pressure, coercion, or manipulation. This means that a person’s agreement must be their own genuine choice. Consent is not valid if it is obtained through threats, intimidation, emotional pressure, misuse of authority, or fear of consequences. Even subtle pressure or persistence can undermine whether consent is truly free.

Consent can be withdrawn at any time. A person has the absolute right to change their mind, even if sexual activity has already begun. Once consent is withdrawn, continuing the activity may amount to a criminal Sexual Offence. It does not matter what was agreed earlier or how far things have progressed — consent must exist at every stage.

Consent must be ongoing throughout any sexual activity. Agreeing to one act does not mean agreeing to all acts, and consent to sexual activity on one occasion does not imply consent on another. Each stage of sexual activity requires consent, and it must continue for as long as the activity continues.

Everyone has the right to say no or change their mind. No one is required to justify their decision, and refusal does not need to be expressed in any particular way. A lack of enthusiasm, hesitation, or uncertainty may indicate that consent is not present. Respecting another person’s right to say no is fundamental to lawful and respectful sexual relationships.

Consent education is one of the most effective tools in preventing Sexual Offences

Consent education is a key preventative tool in reducing sexual violence, Sexual Assault, and sexual harassment. While education is especially important for young people, understanding consent is essential for everyone, regardless of age or relationship status.

Clear education helps to:

Protect potential victims from harm
Prevent misunderstandings that can lead to criminal allegations
Promote respectful and healthy relationships
Reduce the risk of individuals facing serious criminal charges due to lack of understanding

When Consent cannot be given : Understanding capacity, age, and intoxication

Consent is not valid if a person does not have the freedom or capacity to choose. In these circumstances, the law is clear: consent does not exist.

This includes situations where someone is:

Under the age of consent
Too drunk or under the influence of drugs to make a clear decision
Asleep or unconscious
Being pressured, threatened, or manipulated

The age of Consent in the UK

In the UK, the legal age of consent is 16. This means that anyone under the age of 16 cannot legally consent to sexual activity.

Importantly, this applies even if both individuals are under 16. The law does not recognise consent where either party is below the age of 16, regardless of whether the activity appears mutual.

While the criminal justice system may approach cases involving similar-aged teenagers differently depending on the circumstances, the legal position remains the same: a person under 16 does not have the legal capacity to consent to sexual activity.

Understanding this distinction is crucial. Age alone determines legal capacity to consent, and a lack of awareness of the law does not prevent criminal liability.

Common misconceptions about Consent

There are several widespread myths about consent that continue to cause harm:

“If they don’t say no, it means yes.”

NO – silence, hesitation, or uncertainty is not consent. Consent must be clear and positive.

“It’s fine to have sex with someone if they are drunk”

NO – Having sex with someone when they are too drunk to understand what is going on can be sexual assault or rape, as they cannot consent.

“If someone agreed before, they can’t change their mind.”

NO – consent can be withdrawn at any point, including during sexual activity.

“You only need consent when it comes to penetrative sex.”

NO – Sexual activity can take many forms, not all of which involve penetration. Consent is required for every type of sexual activity.

“Consent is automatic in a relationship.”

NO – consent is required every time, even in long-term or committed relationships.

“Flirting means they are ‘Asking for it”

NO – Flirting, being friendly, or dressing in any manner is not an invitation for sexual assault or an excuse for violence.

Conclusion

Under the Sexual Offences Act 2003, a person consents only if they agree by choice and have the freedom and capacity to make that choice. This legal test is central to how courts assess allegations of sexual offences.

A clear understanding of consent, both socially and legally, is essential to protecting individuals, preventing sexual harm, and ensuring fairness for complainants and defendants alike.

Manisha Knights at MK Law

Manisha recently won a case at the Old Bailey where the rape allegation centred on a claim that the complainant withdrew consent after two nights of consensual sexual activity on the morning after the couple’s second date — which our client had always categorically denied. You can find out more info about the case here but after the case she said

The parties had met on Tinder and had two consecutive nights of consensual sex and sexual activity. On the morning following the second night, during sex, the complainant withdrew consent. In cases like this, with mixed signals and even the slightest changes in body language and behaviour when it can be very difficult to judge, people need greater knowledge and awareness that when in any doubt, sex must stop until both parties are on the same page again.

There’s not a written agreement set down when it come to consent so it can become a bit of a grey area – but the more knowledge and understanding people have a round the topic the better, from both perspectives.
