Full Text of Rule 6.150
Plain-English Summary
The rule attaches to intent and to a moment. A party who intends to offer weapons or other hazardous materials in evidence at an evidentiary hearing or trial must complete these steps before bringing the items into the courtroom. Doing it at counsel table is too late.
For weapons the requirements are concrete. All firearms, BB guns, and pellet guns to be offered must be unloaded and either rendered inoperable or fitted with a trigger guard. Guns and ammunition must be kept separate at all times, not merely at the moment of display. Knives, scissors, and any other sharp object that could penetrate the skin must be sealed in puncture-proof containers, given secure and protective sheaths, or otherwise rendered harmless.
For other hazardous materials the rule names two measures. Hypodermic needles need covers over the needle points and must be sealed in a transparent puncture-proof bag. Chemicals, pharmaceuticals, and biological substances need an unbreakable, transparent tube that locks on one end, so the item can be handled and viewed safely without being opened.
The rule's own 1990 note supplies the release valve. The court may grant an exception for good cause shown under UTCR 1.100, and the committee that wrote the rule intended exceptions where a requirement would affect a weapon's mechanical operation and that operation is itself an evidentiary issue. If whether the gun could fire is the question in the case, say so and ask.
Frequently Asked Questions
How do I bring a firearm into the courtroom as an exhibit?
Unloaded, and either rendered inoperable or with a trigger guard installed. Do it before the item comes into the courtroom, and keep the gun and any ammunition separate at all times.
Can the gun and its ammunition be displayed together?
No. The rule requires guns and ammunition to be kept separate at all times. If both are exhibits, they travel and sit apart.
How do I present a knife or other sharp object?
Seal it in a puncture-proof container, provide a secure and protective sheath, or otherwise render it harmless. The rule reaches knives, scissors, and any other sharp object that could penetrate the skin.
What about needles, chemicals, and biological material?
Hypodermic needles get covers over the needle points and are sealed in a transparent puncture-proof bag. Chemicals, pharmaceuticals, and biological substances require an unbreakable, transparent tube that locks on one end, so they can be handled and viewed safely.
What if the weapon has to work for the jury to understand the case?
Ask for an exception. The 1990 note records that the court may grant one for good cause shown under UTCR 1.100, and that the committee intended exceptions where a requirement would affect the mechanical operation of an item when that operation is an evidentiary issue.
