Your Right to Present a Defense in Minnesota

The Right to Testify

Your right to testify in your own defense is protected by both the state and federal constitutions. A few important points:

• The decision is personal to you — your lawyer cannot waive it for you, and any waiver must be knowing and voluntary.
• Because it's a basic constitutional right, your testimony generally cannot be barred on technical grounds like a discovery violation, especially if other measures could address any prejudice to the state.
• If you choose not to testify, that decision is presumed to be made voluntarily and intelligently.

Evidence Rules Cannot Override Your Constitutional Rights

Defense evidence has to comply with the rules of evidence and procedure — but those rules cannot override constitutional requirements. The U.S. Supreme Court has held that defense evidence may not be excluded under any rule that serves "no legitimate purpose" or whose effect is "disproportionate" to its purpose.

In fact, the Supreme Court has struck down several evidence rules as "arbitrary" when used to block a defense, including rules that excluded accomplices as defense witnesses, barred evidence that a confession was coerced, or forbade a defendant's hypnotically refreshed testimony. Even the rape-shield law must give way where it would actually infringe a defendant's constitutional rights.

That said, judges keep real discretion: they can still exclude evidence that is privileged, irrelevant, cumulative, unfairly prejudicial, confusing, or misleading, as long as doing so doesn't undermine a fair trial. Polygraph results, for example, can be excluded.

Showing Someone Else Did It: Alternate-Perpetrator Evidence

One of the most important parts of this right is the ability to raise a reasonable doubt by pointing to another person as the real perpetrator. Minnesota law is notably protective here:

• Under Holmes v. South Carolina, a court cannot exclude this evidence just because the prosecution's case looks strong.
• To get it in, the defense must lay a foundation showing the evidence has an "inherent tendency" to connect the other person to the crime — more than mere presence at the scene or "bare suspicion."
• In State v. Jones, the Minnesota Supreme Court rejected a demanding "clear and convincing" standard for admitting this evidence and stressed that judges should not weigh its credibility — that's the jury's job.

Once the foundation is laid, the defense can also introduce evidence of the other person's motive and even their other crimes or bad acts (sometimes called "reverse-Spreigl" evidence) to cast reasonable doubt.

What this means for you: If the evidence genuinely points toward someone else, you have a constitutional right to put that before the jury. Prosecutors and judges cannot keep it out simply because they find the state's case more convincing.

The Right to Compel and Confront

Your right to present a defense includes the power to compel witnesses and the right to confront those against you:

• Immunity gamesmanship is improper. If a prosecutor charges a potential defense witness and then refuses to resolve the case to keep that person from testifying, that manipulation can be an unethical obstruction of your access to evidence.
• Continuances may be granted if a defense witness isn't immediately available.
• Constitutional rights can outweigh a witness's privilege in some circumstances.
• You're entitled to show the relationship between the victim and a corroborating witness, to impeach identification testimony, and — on a proper foundation — to show that an accuser has made false accusations in the past.

Explaining Your Own Conduct and Statements

Your due-process right to be heard includes the right to explain conduct the state has proved — even if the explanation doesn't relate directly to an element of the offense. And when the state introduces your confession or statement, you have a right to show the "physical and psychological environment" it came from, so the jury can answer the natural question: if you're innocent, why did you say what you said?

The Right to a Complete Defense Presentation

Finally, the right to present a defense includes the right to proper jury instructions (including an instruction on your theory of defense if requested) and the right to make a closing argument. You're entitled to present a connected "chain" of evidence explaining the circumstances — each piece doesn't have to be a complete defense on its own.
