In re Colorado v. Rosas
Annotate this CaseBased on an incident that occurred between January 3 and 4, 2018, the State of Colorado charged Paul Rosas with two counts of second degree assault on a peace officer (class 4 felonies), two counts of attempted second degree assault on a peace officer (class 5 felonies), and one count of obstructing a peace officer (a class 2 misdemeanor). Rosas filed a notice of the affirmative defense of “impaired mental condition” pursuant to section 16-8-103.5, C.R.S. (2019), asserting that at the time of the offenses he was suffering from a mental disease or defect that made him incapable of forming the requisite culpable mental state. But this affirmative defense hadn't existed in Colorado "for a quarter of a century." The State objected to Rosas’s notice of the defense of impaired mental condition, but only on the ground that it was untimely. After a hearing, the district court overruled the State's objection and “allow[ed] [Rosas] to enter an affirmative defense of impaired mental condition.” It then ordered an examination “for impaired mental condition.” The issue this case presented for the Colorado Supreme Court's review centered on whether a defendant charged with specific intent crimes had to plead not guilty by reason of insanity (“NGRI”) in order to introduce evidence that, as a result of a mental disease or defect, he was incapable of forming the requisite culpable mental state on the dates of the offenses charged. The district court said “no.” The Supreme Court ruled the answer was “yes.” "Evidence that a mental disease or defect prevented a defendant from forming the culpable mental state required by an offense charged is evidence relevant to the issue of insanity. And a defendant—even one charged with specific intent crimes—cannot introduce evidence relevant to the issue of insanity without first pleading NGRI."
