Rule 782.1 The possession of a condom is not admissible as evidence in the prosecution of a violation of Section 372 of, or subdivision (a) or (b) of Section 647…

If someone is charged with a prostitution-related crime, the fact that they had a condom on them cannot be used as evidence against them in court.

This means a prosecutor cannot point to a condom as proof that someone was involved in prostitution. Having a condom is not a crime, and it does not show that a person did anything illegal.
