Instruction 7.670, Criminal Model Jury Instructions for Use in the District Court
Carrying a loaded firearm while under the influence [G.L. c. 269, s. 10H]
CARRYING A LOADED FIREARM ON ONE’S PERSON
OR HAVING CONTROL OVER A LOADED FIREARM
IN A VEHICLE WHILE UNDER THE INFLUENCE
G.L. c. 269, § 10H
The defendant is charged with (carrying a loaded firearm on his
person) (having a loaded firearm under his (her) control in a motor
vehicle) while under the influence of (intoxicating liquor) (marijuana)
(narcotic drugs) (depressants) (stimulant substances).
To prove the defendant guilty of this offense, the
Commonwealth must prove the following three things beyond a
reasonable doubt:
First: That the defendant (carried a weapon on their person)
(had a weapon under their control in a vehicle) that met the legal
definition of a firearm;
Second: That the firearm was loaded with ammunition; and
Third: That the defendant was under the influence of
(intoxicating liquor) (marijuana) (narcotic drugs) (depressants)
(stimulant substances) while they (carried the firearm on their person)
(had the firearm under their control in a motor vehicle).
To prove the first element, the Commonwealth must prove the
defendant (carried a weapon on their person) (had a weapon under
their control in a vehicle) and that the weapon met the legal definition
of a “firearm.”
The legal definition of a firearm has three parts. First, it must be
a weapon; Second, it must be capable of discharging a shot or bullet;
and Third, it must have a barrel length of less than 16 inches. The
term “barrel length” refers to “that portion of a firearm. . . through
which a shot or bullet is driven, guided or stabilized, and [includes]
the chamber.”
G.L. c. 140, § 121
If it is alleged that the defendant carried a firearm
To prove the first element, the Commonwealth must also prove
the defendant carried a firearm. A person carries something when
they move it, no matter how slight that movement might be. Such
movement requires no more than momentary possession of the
object.
One carries an object on their person when the object is
physically handled by or attached to the person, or is in the
person’s clothing.
Whether the defendant carried a firearm on their person is
something that you must determine from all the facts and any
reasonable inferences that you choose to draw from those facts.
If it is alleged the defendant had control over a firearm in a vehicle
To prove the first element, the Commonwealth must also prove
the defendant had control over a firearm in a vehicle. It is not enough
for the Commonwealth to prove that the defendant was present in the
same vehicle as the firearm. To prove control over the firearm, the
Commonwealth must also prove that the defendant knew that the
firearm was there, and that the defendant had both the ability and the
intention to exercise control over it. The Commonwealth is not
required to prove that the defendant had exclusive control over the
firearm.
Whether the defendant had control over a firearm in a vehicle is
something that you must determine from all the facts and any
reasonable inferences that you choose to draw from those facts.
To prove the second element, the Commonwealth must prove
the firearm was loaded with ammunition. Ammunition is any
(cartridge or cartridge case) (primer) (igniter) (bullet) (propellant
powder) designed for use in a firearm. A firearm is loaded if
ammunition is contained in the weapon or within a feeding device
attached to it.
G.L. c. 269, § 10(o)
To prove the third element, the Commonwealth must prove that
at the time the defendant (carried a loaded firearm on their person)
(had a loaded firearm under their control in a vehicle), the defendant
was under the influence of (alcohol) (marijuana) (narcotic drugs)
(depressants) (stimulant substances).
If the substance is alleged to be alcohol
What does it mean to be “under the influence” of alcohol?
Someone does not have to be drunk to be under the influence of
alcohol. A person is under the influence of alcohol if he (she) has
consumed enough alcohol to reduce their ability to safely (carry a
loaded firearm on their person) (have a loaded firearm under their
control in a motor vehicle), by decreasing their alertness or judgment.
It means that a person has consumed enough alcohol to reduce their
mental clarity, self-control or reflexes, and thereby left them with a
reduced ability to (carry) (have under their control) a loaded firearm in
a safe manner. The Commonwealth is not required to prove that the
defendant actually (carried a loaded firearm) (had a loaded firearm
under his [her] control) in an unsafe manner, but it is required to
prove that the defendant’s ability to safely (carry a loaded firearm)
(have a loaded firearm under their control) was diminished by the
consumption of alcohol. The amount of alcohol necessary to do this
may vary from person to person. You may rely on your own
experience and common sense about the effects of alcohol on a
person. You should consider any believable evidence about the
defendant’s alleged consumption of alcohol, as well as the
defendant’s appearance, condition, and behavior at the time and
place in question.
Commonwealth v. Veronneau, 90 Mass. App. Ct. 477, 479-80 (2016) (the standard for
intoxication for the crimes of operating a motor vehicle under the influence and carrying a
loaded firearm while under the influence are not necessarily the same).
See Commonwealth v. Riley, 48 Mass. App. Ct. 463, 465 (2000) (noting that the words
“mental clarity, self-control, and reflexes” are “merely examples or factors that the jury
may use in determining whether the consumption of alcohol diminished the defendant’s
capacity [to carry a loaded firearm]” and that the Commonwealth is not required to prove
any of these examples or factors beyond a reasonable doubt).
If there is evidence of a breath or blood test and no per se OUI charge You may
also consider whether a (breath) (blood) test showed that the
defendant had consumed any alcohol. However, the (breath) (blood)
test is not sufficient by itself to prove that the defendant was under
the influence of alcohol.
[As a preliminary matter, in the absence of a judge taking judicial notice upon request of
what a breathalyzer measures, a judge should consider what foundational evidence must
be introduced before admitting breath or blood test evidence. Commonwealth v. Colturi,
448 Mass. 809, 811 (2007) (breath test evidence); Commonwealth v. Filoma, 79 Mass.
App. Ct. 16, 20-21 (2011) (same). See also Commonwealth v. Dyer, 77 Mass. App. Ct.
850, 857 (2010) (blood test evidence).]
If there is evidence of a breath or blood test and defendant is charged with per se OUI
You may also consider whether a (breath) (blood) test showed that
the defendant had consumed any alcohol. However, unlike the
offense of operating under the influence, no matter what the reading
is, the (breath) (blood) test is not sufficient by itself to prove that the
defendant was under the influence of alcohol while (carrying a loaded
firearm on their person) (having a loaded firearm under their control
in a vehicle).
See note 4, infra.
If the substance is alleged to be marijuana, narcotic drugs, depressants, or stimulants)
What does it mean to be “under the influence” of (marijuana)
(narcotic drugs) (depressants) (stimulant substances)? A person is
under the influence of (marijuana) (narcotic drugs) (depressants)
(stimulant substances) if they have used enough of the substance to
reduce their ability to safely (carry a loaded firearm on their person)
(have a loaded firearm under their control in a motor vehicle), by
decreasing their alertness or judgment. It means that a person has
used enough of the substance to reduce their mental clarity, self-control or reflexes, and thereby left them with a reduced ability (to
carry) (have under their control in a motor vehicle) a loaded firearm in
a safe and responsible manner. The Commonwealth is not required
to prove that the defendant actually (carried a loaded firearm) (had a
loaded firearm under their control in a vehicle) in an unsafe manner,
but it is required to prove that their ability to safely (carry a loaded
firearm) (have a loaded firearm under their control in a vehicle) was
diminished by the use of (marijuana) (narcotic drugs) (depressants)
(stimulant substances).
You are to decide this from all the believable evidence in
this case, together with any reasonable inferences that you draw
from the evidence. You may consider evidence about the
defendant's appearance, condition and behavior at the time, in
order to determine whether the defendant’s ability to (carry)
(have under their control in a motor vehicle) a loaded firearm in
a safe manner was diminished by (marijuana) (narcotic drugs)
(depressants) (stimulant substances).
So in summary there are three elements the Commonwealth
must prove beyond a reasonable doubt:
First: That the defendant (carried a weapon on their person)
(had a weapon under their control in a vehicle) that met the legal
definition of a firearm;
Second: That the firearm was loaded with ammunition; and
Third: That the defendant was under the influence of
(intoxicating liquor) (marijuana) (narcotic drugs) (depressants)
(stimulant substances) while they (carried the firearm on their person)
(had the firearm under their control in a motor vehicle).
If the Commonwealth proved all three elements beyond a
reasonable doubt, you should return a verdict of guilty. If the
Commonwealth failed to prove any element beyond a reasonable
doubt, you must find the defendant not guilty.
SUPPLEMENTAL INSTRUCTIONS
1. Roadside Assessments
You heard testimony in this case that the defendant, at the
request of a police officer, performed or attempted to perform various
roadside assessments. These roadside assessments are not
scientific tests of impairment by (alcohol) (marijuana) (narcotic drugs)
(depressants) (stimulant substances) use. A person may have
difficulty performing these tasks for many reasons unrelated to the
consumption of (alcohol) (marijuana) (narcotic drugs) (depressants)
(stimulant substances).
It is for you to decide if the defendant’s performance on these
roadside assessments indicate that their ability to (carry) (have under
their control in a motor vehicle) a loaded firearm in a safe manner was
diminished by (alcohol) (marijuana) (narcotic drugs) (depressants)
(stimulant substances).
You may consider this evidence solely as it relates to the
defendant’s balance, coordination, mental clarity, ability to retain and
follow directions, ability to perform tasks requiring divided attention,
and other skills you may find are relevant to safely (carrying) (having
under their control in a motor vehicle) a loaded firearm.
It is for you to determine how much, if any, weight to give the
roadside assessments. In making your determination, you may
consider what the officer asked the defendant to do, the
circumstances under which they were given and performed, and all of
the other evidence in this case.
Finally, evidence of how a defendant performed in roadside
assessments, standing alone, is never enough to convict a defendant
of (carrying) (having under their control in a motor vehicle) a loaded
firearm while under the influence.
See Commonwealth v. Gerhardt, 477 Mass. 775, 785, 789 (2017).
2. Factors that may affect reliability of breath or blood testing
In deciding whether to rely on evidence about a (breath) (blood)
test, you may consider evidence, if any, about:
• whether the test was administered within a reasonable time of
operation;
• whether the person who gave the test was properly certified, and
your assessment of (his) (her) credibility;
• the pre-test procedures that were employed;
• whether the testing device was in good working order at the time
the test was administered;
• whether the test was administered properly; and
• any other evidence pertaining to the administration of the test.
3. If there is an issue regarding any delay in blood or breath testing
A passage of up to three hours between testing and the time of the
alleged offense may be reasonable, however the facts and
circumstances of the case may suggest that a greater or lesser time
period might apply. Ultimately it is up to you to decide what is
reasonable.
