Legal Question in Criminal Law in California

If the conviction has been reversed or set aside for the reasons you describe then it cannot be counted as a strike. But if it remains in place and the defendant merely claims that the evidence against him was falsified, the courts will not question its legitimacy. A court considering a later charge against the same defendant will not overlook a prior conviction just because the defendant says he was the victim of perjury.

Convicted is convicted, regardless of claims of innocence. If the 3 strikes rules apply, they will be imposed.
