Proposition 69 requires misdemeanants who must register as sex offenders to provide DNA samples regardless of whether their conviction occurred before or after the passage of Proposition 69. Good was convicted of indecent exposure in 1996, and was required to annually register as a sex offender under Penal Code section 290. At the time of his conviction, he was not required to provide a DNA sample. In 2004, Proposition 69 changed the law to mandate that all persons required to register as sex offenders submit DNA samples. In 2005, Good was sent a letter directing him to report to the police department to provide a sample. He petitioned the appellate court for a writ of prohibition. The appellate court denied the writ. The electorate intended misdemeanant sex offenders to submit DNA samples regardless of the date of their misdemeanor conviction.
