Which of the following statements is true regarding consent during a search?

The statement that each occupant can override another's consent accurately reflects principles of consent in legal searches. In situations where multiple occupants have a shared interest in a space, such as an apartment or a vehicle, the law recognizes that each individual has the right to withdraw consent if they do not agree with the search. This means that one occupant can indeed refuse consent, which would typically invalidate any consent given by another occupant regarding the search.

For instance, if one person in a shared living arrangement consents to a search while another opposes it, the opposing person's lack of consent can result in the search being deemed unlawful, as individuals have a reasonable expectation of privacy in their joint living spaces. This principle recognizes the rights of all individuals involved, ensuring that no single person's consent is deemed legally sufficient to override the rights of others with an equal claim to the space.

In contrast, the other statements do not accurately uphold legal standards regarding consent in search situations. Consent can be revoked under various circumstances, it does not have to be non-verbal, and generally one person cannot consent for everyone unless they have specific authority or ownership over the shared space.
