The People of the State of Colorado, Petitioner v. Larry Wayne Marquardt, Respondent

Summary

The court held that the governing four-part test for involuntary antipsychotic medication also applies when the State seeks to increase a patient's medication dose over the patient's objection. It further held that a stable patient’s lack of improvement, without evidence of significant and likely long-term deterioration or danger of serious harm, does not satisfy that test. Because the trial court relied on the prospect of improvement rather than deterioration, the court affirmed the court of appeals and remanded for consistent proceedings.
