Balbirnie v. State, 468 P.3d 334

John Balbirnie was convicted of second-degree murder for the fatal stabbing of Paul Nicholson and consistently maintained his innocence.
At trial multiple witnesses (including Phillip Wallace, Brandon Ellsmore, and Tarissa Brown) gave inconsistent accounts; some later implicated Balbirnie while others denied seeing Wallace with a weapon.
A contemporaneous 911 recording made by Brown, in which she says "My fiancé stabbed him," identified Wallace as the stabber; the recording was in discovery but not admitted at trial.
Trial counsel received and reviewed the 911 tape, considered it exculpatory, but failed to lay foundation or subpoena Brown to authenticate it, later testifying this was an oversight rather than strategy.
Balbirnie filed a K.S.A. 60-1507 ineffective-assistance claim; the district court denied relief, the Court of Appeals found deficient performance but no prejudice, and the Kansas Supreme Court reversed and ordered a new trial.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether counsel's failure to introduce the 911 call was constitutionally deficient performance	Counsel's omission was not strategic, and the tape was exculpatory—identifying Wallace as the stabber	The omission was reasonable or strategic; counsel expected State to admit tape; foundation issues made admission impractical	Court agreed performance was deficient: counsel's failure to admit the tape fell below objective standard
Whether counsel's deficiency prejudiced the defense (Strickland prejudice prong)	The 911 tape was contemporaneous, impeached key witnesses, and created a reasonable probability of a different verdict	The record contained strong inculpatory evidence (witnesses, blood evidence, defendant's statements/video); the tape was emotional/confusing and not dispositive	Court held prejudice established: reasonable probability the outcome would differ; conviction reversed and new trial ordered
