This policy highlights the risks in sexual or romantic relationships in the Stanford workplace or academic setting between individuals in inherently unequal positions; prohibits certain relationships between teachers and students; and requires recusal (from supervision and evaluation) and notification in other relationships.
There are special risks in any sexual or romantic relationship between individuals in inherently unequal positions, and parties in such a relationship assume those risks.
These circumstances usually involve cases in which a person is not mentally or physically capable of choosing whether to engage in sexual behavior.
For instance, if someone is drunk or high on drugs, then that person cannot give consent.
Finally, if you're unsure what rights you have in a sexual encounter, such as the right to stop giving consent and end the encounter at any time, read Sexual Rights.
