People v. Treadway, G038824

Sentence pursuant to Vehicle Code section 23550 after defendant suffered his fourth DUI conviction within a 10-year period is affirmed over claims that the current section 23550, as applied to him: 1) constitutes an ex post facto law; 2) violates due process rights; and 3) contravenes principles of estoppel because the oldest of his fourth DUI offense was more than 7, but less than 10, years old at the time the amended statute went into effect.
