In what context might the prosecution introduce evidence of a victim's sexual behavior?

The correct context for introducing evidence of a victim's sexual behavior would be to prove the origin of physical evidence. This situation arises in cases where the evidence is directly relevant to the case and can help establish the source or nature of physical evidence found. For instance, if there is a physical sample that suggests prior sexual activity, the prosecution may introduce evidence of the victim's sexual behavior to clarify the origins of that sample and how it might relate to the events in question.

In other scenarios, such as refuting claims of consent, the relevant evidentiary rules, like the Rape Shield Law, typically limit the admissibility of a victim's sexual history to protect against prejudicial implications. Instead, the focus remains on the specific incident rather than the victim's past sexual behaviors. The same logic applies to establishing a pattern of behavior or supporting allegations made by the accused, as these aims generally do not justify the introduction of such sensitive evidence in most legal contexts.
