Legal Question in Criminal Law in California

Offhand I don't know what range of sentences your boyfriend faces. But I can tell you that the acquittals are final. The government cannot appeal an acquittal. Regardless of what happens in your boyfriend's appeal, he cannot be re-tried on those counts.

There are narrow exceptions to this rule, and they rarely come up. An example is where the defendant has tampered with the judge or jury. The rationale is that a new trial is not double jeopardy because the defendant was never in jeopardy to begin with.
