Background
A jury convicted Demont M. Vandunk of first-degree robbery, armed criminal action, and aggravated fleeing a stop or detention. The charges arose from an armed robbery in which Vandunk restrained a mobile detailer while an accomplice displayed a handgun and took the victim’s property and a Corvette. Police later pursued Vandunk in a Camaro, and he fled on foot after crashing.
The State charged Vandunk as a persistent offender based on two prior felony convictions. In a bifurcated proceeding designed to address the U.S. Supreme Court’s decision in Erlinger v. United States, the jury found that the State had not proved Vandunk had the alleged convictions. Vandunk requested jury sentencing, but the trial court dismissed the jury because it believed it had implicitly found him to be a prior offender before submission. The court later acknowledged that it had not expressly made the required finding, but denied a new trial for lack of prejudice and imposed unenhanced sentences totaling 25 years.
The Court’s Holding
The Court of Appeals affirmed. It held that Vandunk failed to preserve the claim presented on appeal: that the trial court committed structural due-process error by deviating from a bifurcated procedure agreed upon by the parties. At trial, Vandunk had consistently opposed bifurcation as unauthorized by Missouri law, and his request for jury sentencing rested principally on the absence of a timely prior-offender finding. He could not recast those objections on appeal as a constitutional challenge to departure from an agreed procedure.
The court declined discretionary plain-error review. Missouri’s right to jury sentencing is statutory, not constitutional, so its denial is not structural constitutional error. Even assuming the trial court erred by dismissing the jury without first making the required prior-offender finding, Vandunk did not show that the error affected the fairness of his trial. His sentences fell within the ordinary, unenhanced ranges, and the court would not speculate that a jury would have recommended lesser punishment.
Key Takeaways
- An appellate claim is unpreserved when it materially changes the objection asserted at trial and in the motion for new trial.
- Missouri’s right to jury sentencing is statutory rather than constitutional, and deprivation of that right is not automatically reversible structural error.
- A defendant seeking reversal for denial of jury sentencing must demonstrate actual prejudice; courts will not presume that a jury would have recommended a lighter sentence.
Why It Matters
The decision underscores the importance of preserving the same legal theory throughout trial, post-trial proceedings, and appeal, particularly when asserting constitutional error. An intervening decision undermining a trial objection does not permit an appellant to replace it with a materially different theory.
It also confirms that erroneous denial of Missouri jury sentencing requires a concrete showing of prejudice. Where the court imposes lawful, unenhanced sentences and no jury recommendation exists for comparison, speculation about a potentially lower jury sentence will not support reversal.
