The Law's Consent Problem: Definitions Betray Autonomy

Consent is the foundation of sexual ethics and the bedrock of sexual assault law. Yet its legal definition remains one of the most contested and inconsistent elements of criminal justice systems worldwide. How a legal system defines consent reveals its assumptions about gender, autonomy, power, and the body. And those assumptions, across jurisdictions, are deeply revealing.

"Consent is not the absence of 'no.' It is the presence of 'yes.' But the law is still learning to tell the difference."

The Spectrum of Consent Models

Legal systems generally fall along a spectrum of consent models. At one end is the **force-based model**, which defines sexual assault primarily in terms of physical force — a attacker uses violence or threats to overcome resistance. At the other end is the **affirmative consent model**, which requires active, enthusiastic, and ongoing agreement to sexual activity.

The force-based model, historically dominant in most legal systems, places the burden on the victim to demonstrate that she resisted. Resistance could be physical (fighting back), verbal (saying "no"), or circumstantial (evidence of injury, torn clothing, witnesses). This model has been widely criticized for centering the victim's behavior rather than the perpetrator's conduct — for asking "why didn't she fight back?" instead of "why did he continue?"

The **affirmative consent model** — adopted in various forms in Sweden, parts of Australia, California, and several other jurisdictions — shifts the question to whether the defendant took active steps to ensure consent. Under this model, silence, intoxication, or the absence of physical resistance does not constitute consent. The defendant must demonstrate that they obtained a clear, affirmative agreement.

Sweden: The Gold Standard?

Sweden's consent-based sexual offense law, reformed in 2018, is often held up as a model. The new law defines rape as any sexual act that takes place without the other person's voluntary participation. The defendant's intent is no longer central — what matters is whether the other person consented, regardless of whether the defendant "knew" they didn't.

The Swedish model represents a fundamental shift in legal thinking. It treats consent as the responsibility of the person initiating sexual activity, not the person being subjected to it. It recognizes that "no" is not the only way to express non-consent — that freezing, complying, or failing to resist are also responses to coercion.

But the Swedish model is not without critics. Some argue that it is too broad — that it criminalizes ambiguous situations where both parties may have genuinely believed consent was present. Others point to enforcement challenges: in the absence of physical evidence, consent disputes often come down to one person's word against the other, and juries may be reluctant to convict without evidence of force.

India: The Consent Gap

India's legal framework on consent is defined primarily by what it does not cover. Section 375 of the Indian Penal Code (now Bharatiya Nyaya Sanhita) defines rape in terms of consent, but with significant gaps. Consent obtained through "intoxication" or from a woman "under eighteen" is not valid — but consent obtained through deception, power dynamics, or ongoing coercion within relationships is largely unrecognized.

The most significant gap is the marital rape exception, which we have discussed elsewhere. But there are others. India has no affirmative consent model — the prosecution must typically prove the absence of consent, rather than the defendant proving its presence. And the cultural expectation that women will resist physically — that a "real" victim will fight back — persists in police stations and courtrooms despite decades of feminist advocacy.

The **2013 Criminal Law Amendment**, passed in the wake of the Nirbhaya case, expanded the definition of sexual assault and introduced stricter penalties. But it did not adopt an affirmative consent model, and the definition of consent remains rooted in the concept of "voluntary agreement" — a standard that is difficult to prove when power imbalances, intoxication, or coercion are present.

"In India, the law asks: did she say no? In Sweden, the law asks: did he ask? The distance between those two questions is the distance between two different conceptions of justice."

The Affirmative Consent Model in Practice

Jurisdictions that have adopted affirmative consent models have seen mixed results. In California, where the "Yes Means Yes" law took effect in 2015, colleges and universities are required to adopt affirmative consent policies for sexual misconduct proceedings. Evaluations of the law's impact suggest that it has shifted institutional culture — making consent a more visible and discussed concept — but has not significantly increased reporting or adjudication of sexual assault cases.

In Australia, consent laws vary by state, with some adopting affirmative models and others retaining force-based approaches. Research by **Professor Julia Quilter** at the University of Wollongong has documented the challenges of implementing affirmative consent in practice: jurors bring their own assumptions about "normal" sexual behavior, prosecutors struggle to prove the absence of consent, and judges sometimes instruct juries in ways that undermine the statutory framework.

The lesson from these jurisdictions is that legal reform is necessary but insufficient. Affirmative consent laws change the text of the statute, but they do not automatically change the culture of the courtroom, the assumptions of the jury, or the attitudes of the police. For consent laws to be effective, they must be accompanied by education, training, and a sustained cultural shift.

The Unresolved Questions

Consent law continues to evolve, and several questions remain unresolved. How should the law handle situations where both parties are intoxicated? What role should power dynamics — employer-employee, teacher-student, doctor-patient — play in the legal definition of consent? How should the law address ongoing consent within relationships, where sexual activity is frequent and the lines between autonomy and obligation are blurred?

These are not abstract questions. They are the daily reality of sexual assault cases in courtrooms around the world. And they require answers that center the experiences of survivors — not the convenience of legal systems that were designed in a different era.

The right to say no is not enough. The law must recognize the right to say yes — actively, freely, and without coercion — and the obligation of every person to seek that yes before acting.
