State v. Guebara, 544 P.3d 794

Paul Guebara was charged and convicted in Kansas state court of attempted first-degree murder and criminal possession of a weapon by a felon, based on shooting a man after an argument.
Guebara stipulated at trial that he had been convicted of "a felony crime" within the preceding 10 years, but did not specify whether it was a felony that legally barred him from possessing a weapon.
The jury convicted Guebara on both charges. On appeal, the Kansas Court of Appeals reversed the weapons conviction, holding the stipulation insufficient under recent Kansas Supreme Court precedent.
The Supreme Court of Kansas reviewed whether a generic prior felony stipulation is enough for the criminal possession charge, and whether any procedural errors were harmless.
Guebara, proceeding pro se on appeal, raised multiple additional issues relating to ineffective assistance of counsel, hearsay, prosecutorial error, alleged Brady violations, right to appellate counsel, cumulative error, and the Confrontation Clause.
The State cross-petitioned on the Confrontation Clause issue regarding a witness's unavailability.

Issue	Guebara’s Argument	State’s Argument	Held
Adequacy of prior felony stipulation	The generic stipulation did not prove he was a prohibited person under the statute.	The stipulation to “a felony crime” is sufficient, per prior precedent.	Stipulation was inadequate, but error was harmless because State put proper evidence on record.
Jury-trial waiver for stipulation	Court failed to secure explicit waiver; this was constitutional error.	A waiver is required, but any error was harmless here.	Waiver should have been obtained, but error was harmless beyond a reasonable doubt.
Right to appellate counsel	He was denied effective appellate representation.	Guebara had counsel but chose to proceed pro se; no violation occurred.	No constitutional violation; panel acted within discretion.
Ineffective assistance of trial counsel	Counsel failed to investigate, object, and allowed false/testimonial evidence.	Counsel's performance met professional standards.	District court’s finding of no deficiency/adverse impact was supported.
