What it's about

It wiped out the Kansas Supreme Court’s ruling (vacated it) and sent the case back to that court (remanded).

The dispute was about how the Fifth Amendment right against self-incrimination applies when a defendant raises a mental-incapacity defense.

Question presented

Did the state violate the defendant's Fifth Amendment right to avoid self-incrimination by bringing in evidence from the court-ordered mental evaluation of the defendant to rebut an affirmative defense based on mental incapacity?

What the Court decided

Holding

The rule of Buchanan, reaffirmed here, applies in this case to permit the prosecution to offer the rebuttal evidence at issue. Pp. 4– 10. 295 Kan. 229, 284 P. 3d 1007, vacated and remanded.

Result
Vacated

The Court's reasoning

The Court said its earlier rule from Buchanan, reaffirmed in this case, permits the prosecution to offer the rebuttal evidence.
