Generally, a Washington criminal law must be sufficiently specific to notify an ordinary person of what conduct it prohibits and provide ascertainable standards of guilt to prevent arbitrary enforcement. In a recent case, a defendant challenged the statute prohibiting being in actual physical control of a motor vehicle while under the influence after she was found sleeping in the passenger seat of her parked vehicle.
The defendant was charged with being in actual physical control of a motor vehicle while under the influence. According to the appeals court’s opinion, an officer found her sleeping in the passenger seat of her vehicle while parked with the engine running. She moved to dismiss, arguing the law was unconstitutionally vague.
The city argued the statute was constitutional and that “actual physical control” can include someone in the passenger seat of a non-moving vehicle.
