Co-Defendants and Separate Trials

Colorado Courts Co-Defendant’s in Colorado criminal cases many times -as a matter of strategy and tactics do NOT want to be tried together. One reason may be that in a joint trial the more guilty of the two one with perhaps a much worse criminal history tends to “shade” the case against the less guilty of the two.. In this situation the former defendant will seek a severance of the trials this article addresses that issue.

Colorado Law of Severance As A Matter of Right vs A Matter of Judge Based Discretion

The Rule in Colorado is that severance is to be granted as a matter of right if there is material evidence admissible against one but not all of the parties and admission of that evidence is prejudicial to the party against whom the evidence is not admissible.

Even if the evidence at issue would be inadmissible against the defendant seeking severance, severance is not mandatory unless it is also shown that the evidence is prejudicial to the moving defendant.

To establish prejudice for the purposes of § 16-7-101, the defendant must show that the evidence was so inherently prejudicial that the jury could not have limited its use to a proper purpose.

Here is The Specific Colorado Law on Severance (each section is “broken out” so that it is easier to understand):

§ 16-7-101. Separate Trial of Joint Defendants

When two or more defendants are jointly indicted or informed against for any offense and there is material evidence, not relating to reputation, which is admissible against one or some of them but which is not admissible against all of them if they are tried separately and which is prejudicial to those against whom it is not admissible, those against whom such evidence is admissible shall be tried separately upon motion of any of those against whom the evidence is not admissible. In all other cases, defendants jointly prosecuted shall be tried separately or jointly in the discretion of the court.

The Law As Interpreted By The Colorado Courts

This section is mandatory when it appears that a defendant would be prejudiced on a joint trial by the admission of evidence which would not be admissible as against him, but which would be competent as against his co-defendant.

A defendant is entitled to severance of trial as a matter of right if there is evidence that is admissible against one but not all of the parties and if the evidence is prejudicial to the defendant against whom the evidence is not admissible.

The supreme court has interpreted this section to mean, in the mandatory severance setting, that the trial court must determine whether the admitted evidence was so inherently prejudicial that the jury could not have limited its use to its proper purpose.

The Trial Judge’s Decision to Sever The Trials Or Not To Sever The Trials Will Be Upheld On Appeal

The trial court’s decision will be upheld on appeal absent a showing of an abuse of discretion and actual prejudice to the moving party. Severance is to be based upon a finding of prejudice rather than simply the differences which are incidental to any trial of more than one defendant.

Joint Indictments And Discretionary Severance

Where two defendants are indicted jointly, and there is evidence not relating to reputation, admissible as against one of them, but inadmissible as against the other, the one against whom such evidence is inadmissible is entitled to a separate trial as of right under this section.

BUT where the evidence is admissible against all defendants, severance need not be allowed.

And such this as evidence of reputation of another defendant is expressly excluded as a ground for severance by this section.

When an out-of-court statement of a co-defendant does not make reference to the co-defendant, severance should be granted only when it is necessary to promote a fair determination of the guilt or innocence of one or more defendants.

The court should make this determination by considering, among other factors, whether, in view of the number of offenses and defendants charged and the complexity of the evidence offered, the trier of fact will be able to distinguish the evidence and apply the law intelligently as to each offense and as to each defendant.

Severance Of Trials That Is Within The Authority (The Discretion) of the Trial Judge

If a defendant is not entitled to a severance as a matter of right, a motion for severance is addressed to the sound discretion of the trial court, whose decision will be affirmed absent a showing of abuse of discretion and actual prejudice to the moving party.

The factors to be considered in determining whether denial of a severance constitutes an abuse of discretion include:

  1. whether the number of defendants or the complexity of evidence is such that the jury will confuse the evidence and the law applicable to each defendant;
  2. whether, despite admonitory instructions, evidence admissible against one defendant will improperly be considered against another; and
  3. whether the defenses are antagonistic.
What is not an Antagonistic Defense?

Defenses are not antagonistic where they do not specifically contradict each other. Therefore where joint defendants merely deny participation in the crime and do not present evidence or testimony that the other defendant was solely responsible, arguments made by the lawyers that suggest that the other defendant was responsible for the crime does NOT establish the existence of antagonistic defenses.

"I found myself in criminal trouble, that I wasn't guilty of and thanks to Mr. Steinberg's dedication and hard work, right before we we're looking at having to continue on to trial level Mr. Steinberg was able to use his vast knowledge of the law and his many respected years in the system to find a way to show my innocence. After a very unsure and somewhat difficult time for me, this very skilled and knowledgeable attorney was able to find the right path to take to reach a dismissal in my case. For that I can't tell you how much I appreciate his representation and his excellent understanding and helpful personality. He's a great man and an even better attorney but don't misunderstand him, he is an attorney not a therapist. Thanks H." Josh
