Can a single episode contain valid consent to drug use and invalid consent to sex? What does this imply for theories that treat consent as global to a “scene”?
The question presses on a structural feature of consent that is often left implicit: its unit. When someone consents, what is the object of their consent? A particular act, a type of act, a course of conduct, or a “scene”, a bounded episode with an agreed shape? The answer matters for intoxication cases because drug use and sexual activity frequently occur within one episode, and the validity conditions for consent may be satisfied for one and not the other.
The easy answer and its basis
The easy answer is yes. Consent is act-indexed: it attaches to acts under descriptions, as Tom Dougherty’s work on the scope of consent emphasises. Consenting to x does not entail consenting to y, even where y is foreseeable given x. Validity is also time-indexed: capacity, information and voluntariness are assessed at the time of the consent, or at the time of the act consented to, depending on one’s theory. A person can satisfy the validity conditions when she decides to take a drug and fail them an hour later, when she is asked or assumed to agree to sex. Nothing in the logic of consent prevents the two from coming apart. Indeed, given that the drug impairs the capacities on which validity depends, the first consent can bring about the conditions that defeat the second.
Global or scene-based theories
Some practices and theories, however, treat consent as attaching to a larger unit. The clearest example is the negotiation of a “scene” in BDSM communities. Participants agree in advance on the shape of an encounter, its limits and a signal for stopping, and consent to the scene as a whole. Within it, particular acts need not be individually requested, and some scenes deliberately include acts the participant will appear to resist. Theorists sympathetic to these practices argue that scene-level consent can be valid and can authorise acts that would otherwise require contemporaneous agreement.
Analogous structures appear elsewhere: advance consent to medical procedures under anaesthesia, consent to a contact sport, or the idea, sometimes floated in discussions of long-term relationships, that a standing agreement can cover future encounters.
If consent can be global to a scene, one might ask whether a person who enters an episode involving drugs and sex has consented to the episode as a whole, so that the drug-use consent and the sex consent are not separate after all.
Why the scene model does not license this inference
There are three reasons why scene-based consent, even if valid in its home context, does not support collapsing drug-use consent into sex consent.
First, scene consent is explicit and specific. Its legitimacy depends on prior negotiation in which the content of the scene is articulated and agreed. An episode that merely happens to include drug use and then sex has no such negotiation. There is no scene, only a sequence of events. To treat the sequence as a scene would be to invent an agreement after the fact.
Second, scene consent preserves revocability. Safewords and similar mechanisms exist precisely to keep the participant’s authority over the encounter live throughout it. They are what make scene-level consent compatible with the principle that consent can be withdrawn. Where intoxication removes the capacity to use such a mechanism, scene consent itself loses its justification. Practitioners recognise this; community norms commonly discourage heavy intoxication during scenes for exactly this reason.
Third, scene consent is consent to acts with others whose identities and roles are agreed. A group episode in which participants are not individually agreed, or change during the night, lacks the specificity that scene consent requires.
What this implies for global theories
The upshot is not that global or scene-based consent is incoherent, but that its validity depends on features that typical intoxication cases lack. A global theory, to be defensible, must specify conditions such as advance specification, revocability preserved throughout, and capacity to exercise revocation, that make global consent an extension of the agent’s authority rather than a surrender of it. Once these conditions are specified, they rule out treating an unnegotiated intoxicated episode as a scene.
This yields a useful constraint on theories of consent generally: any theory that allows consent to have a scope wider than a single act must explain how the person’s authority over later acts is preserved. Advance consent is permissible when it is a way of exercising authority over the future, not when it is a way of losing it.
Diachronic agency and the drug-taking decision
There is a residual philosophical issue. A person who takes a drug knowing that it lowers inhibitions may be making a choice about her future self, roughly analogous to Ulysses binding himself to the mast, but in reverse: loosening rather than tightening. Can such a choice authorise what the loosened self later agrees to?
The analogy with Ulysses points the other way. Ulysses’ advance instruction is honoured because it protects his considered will against a predictable distortion. A decision to take a drug is not an instruction to others to treat one’s later intoxicated tokens as authoritative. Absent such an instruction, explicitly given and specific, others have no warrant to treat them so. And even if such an instruction were given, it would face the revocability constraint above.
Implications for the case
In the case behind these seminars, the reported reasoning that the complainant’s conduct was “voluntary, conscious, and consensual” risks treating the night as a unit. The philosophical analysis suggests that this is the wrong unit. Even on the most favourable reading of the disputed facts about drug use, the validity of consent to each sexual act would have to be assessed separately, at the time of that act, against her capacity then.
A productive seminar exercise is to construct the strongest possible scene-based argument for global consent in a case involving intoxication, and then identify exactly which condition it fails.
