Penal Code 647(a) is lewd or dissolute conduct in a public place, or a place open to or exposed to public view.
It is a misdemeanor — and, importantly, unlike indecent exposure (PC 314), it does not require mandatory sex-offender registration.
What PC 647(a) Says
PC 647(a) covers soliciting or engaging in lewd or dissolute conduct in a public place or a place open to public view. California case law makes the elements demanding: the conduct must be sexual, and it must occur where the person knew or should have known that another person who might be offended was present. Conduct in a genuinely private or empty place typically does not qualify.
No Sex-Offender Registration
This is the point that matters most to clients. Unlike indecent exposure (PC 314) and sexual battery (PC 243.4), a conviction under PC 647(a) does not carry a mandatory PC 290 registration requirement. That is why resolving a case as 647(a), rather than a registerable offense, is often a central defense goal.
Defenses
- No one present who might be offended, or a genuinely private setting.
- The conduct was not lewd in the legal sense — not sexual, or not intended to arouse or offend.
- Entrapment in decoy-sting cases.
- Insufficient evidence beyond an officer’s account. judicial diversion (PC 1001.95) may resolve an eligible case.
