Under settled rules of statutory construction, Penal Code section 12022.1 applies where, as here, the only felony a defendant commits while released on bail is a failure to appear in violation of Penal Code section 1320.5. Because a section 12022.1 on bail enhancement is not based on the same act or omission for which punishment is authorized under section 1320.5, sentencing may be imposed under both statutes without violating Penal Code section 654’s prohibition against multiple punishment.
