Instruction 2.120, Criminal Model Jury Instructions for Use in the District Court
Function of the jury; what is evidence; credibility of witnesses
FUNCTION OF THE JURY
WHAT IS EVIDENCE
CREDIBILITY OF WITNESSES
Your function as the jury is to determine the facts of this case.
You alone determine what evidence you believe, how important any
evidence is that you do believe, and what conclusions to draw from
that evidence. In making these determinations, you are to use your
common sense, life experience, and good judgment.
You are to decide what the facts are solely from the evidence
admitted in this case. In evaluating the evidence and determining the
facts, keep in mind that we all tend to perceive information and form
opinions based on our own personal experience and background.
This tendency may cause us to hold biases of which we may or may
not be conscious. As I previously instructed you, you must not allow
bias – whether held consciously or subconsciously – to interfere with
your ability to fairly evaluate the evidence, apply the law as I instruct
you, or render a fair and impartial verdict based on the evidence
before you.
The evidence consists of the testimony of witnesses, as you
recall it, (any documents or other things that were received into
evidence as exhibits) (and any fact on which the lawyers have agreed
or which I have told you that you may accept as proved).
[See Instruction 2.240 (Direct and Circumstantial Evidence) for additional instructions on direct and
circumstantial evidence].
The following instruction should not be given if a defendant is pursuing a Bowden
defense and the judge has decided not to issue the so-called Bowden instruction
(Instruction 3.740, Omissions in Police Investigation). In such a case, the following
instruction could have the effect of undermining the defendant’s Bowden defense
because it references concepts that could be relevant to a claim that there were
omissions in the police investigation. See Commonwealth v. Grier, 490 Mass. 455, 475
(2022); Commonwealth v. Alvarez, 480 Mass. 299, 318 (2018). The court retains
discretion to address with the defendant any objections to the instruction.
Otherwise, proceed with instruction as written.
Picture in your minds that all of the evidence –
[(testimony) (exhibits) (stipulations)] – went into a box. That
box is now closed. Your verdict(s) must be based on what
is in the box, together with any reasonable inferences you
choose to draw from it.
Your determination of the facts must not be based on
speculation or conjecture. During your deliberations one of
you might say, “what about this?” or “what about that?”
Well, if the “this” or the “that” is not in the box – if it is mere
guesswork – don’t consider it.
In short, base your verdict on the evidence and any
reasonable inferences you choose to draw from it, but do
not guess or speculate about things about which there is no
evidence.
Of course, the quality or strength of the proof is not determined
by the sheer volume of evidence or the number of witnesses. It is the
weight of the evidence that is important.
Some things that occur during a trial are not evidence and you
may not consider them as evidence in deciding the facts of this case.
The complaint itself is not evidence. A question put to a witness is
never evidence; only the answers are evidence. [(Also, you may not
consider any answer that I struck from the record and told you to
disregard. Do not consider such answers.) (You may not consider
any item that was marked for identification but was never received in
evidence as an exhibit.)] Anything that you may have seen or heard
when the court was not in session is not evidence.
The opening statements and the closing arguments of the
lawyers are not evidence. They are only intended to assist you in
understanding the evidence and the contentions of the parties. If
your memory of the testimony differs from the attorneys’, you are to
follow your own recollection. You should not consider anything I
have said or done during the trial as any indication of my opinion as
to what your verdict(s) should be.
In evaluating a witness’s testimony, you have to decide what
testimony to believe, and how much weight to give that testimony.
You should give the testimony of a witness whatever degree of belief
and importance that you judge it is fairly entitled to receive.
You are the sole judges of the credibility of a witness. You may
believe everything a witness says, part of it, or none of it. If there are
any conflicts, discrepancies, or inconsistencies in the testimony, you
should examine them carefully. You may consider whether a witness
was candid or guarded, responsive or evasive, and whether the
testimony is reasonable or unreasonable, probable or improbable.
You may take into account how good an opportunity a witness had to
observe the facts about which the witness testifies, and whether the
testimony seems accurate. You may also consider evidence, if any,
about a witness’s motive for testifying, whether a witness displays
any bias in testifying, and whether or not a witness has any interest in
the outcome of the case.
In deciding whether to believe a witness and how much
importance to give a witness’s testimony, you must look at all the
evidence, drawing on your own common sense, life experience, and
good judgment.
Consider the evidence as a whole. Do not make up your mind
about what the verdict should be until after you have gone to the jury
room to decide the case, and you and your fellow jurors have
discussed the evidence. Keep an open mind until then. Once you
have determined the facts, apply the law as I explain it to you to the
facts in order to decide the verdict(s).
The credibility of witnesses is always a jury question, Commonwealth v. Sabean, 275
Mass. 546, 550 (1931); Commonwealth v. Bishop, 9 Mass. App. Ct. 468, 471 (1980), and
no witness is incredible as a matter of law, Commonwealth v. Hill, 387 Mass. 619, 623-24
(1982); Commonwealth v. Haywood, 377 Mass. 755, 765 (1979). Inconsistencies in a
witness's testimony are a matter for the jury, Commonwealth v. Clary, 388 Mass. 583, 589
(1983); Commonwealth v. Dabrieo, 370 Mass. 728, 734 (1976), which is free to accept
testimony in whole or in part, Commonwealth v. Fitzgerald, 376 Mass. 402, 411 (1978).
Disbelief of a witness is not affirmative evidence of the opposite proposition.
Commonwealth v. Swartz, 343 Mass. 709, 713 (1962).
In charging on credibility, the judge should avoid any suggestion that only credible
testimony constitutes evidence. See Commonwealth v. Gaeten, 15 Mass. App. Ct. 524,
531 (1983).
SUPPLEMENTAL INSTRUCTIONS
1. Stipulations of fact or stipulation to an element of the offense. The
Commonwealth and the defendant have agreed, or stipulated, that
______________. This means that they both agree that this is a fact.
You are therefore to treat this fact as undisputed and proved.
“[W]hen the defendant and the Commonwealth have agreed to stipulate to the existence
of an element in a case, the stipulation should be placed before the jury before the close
of the evidence. Such a rule is consistent with the acknowledged burdens of production
and proof that rest with the Commonwealth in a criminal case.” Commonwealth v. Ortiz,
466 Mass. 475, 484 (2013). It is incumbent on the prosecution to ensure that the stipulation
to the element is provided to the jury by some means, and failure to do so may result in a
substantial risk of a miscarriage of justice. See Commonwealth v. Kurko, 95 Mass. App.
Ct. 719, 721-722 (2019).
Under Mass. R. Crim. P. Rule 23, a stipulation to an element of the offense must be
memorialized in writing and must be signed by the Commonwealth, defense counsel, and
the defendant. It shall be read to the jury prior to the close of the Commonwealth’s case in
chief and may be introduced as an exhibit.
Where the evidence includes a stipulation to all of the facts, the defendant “in effect
relinquishes the same rights as one who pleads guilty,” and the judge must offer the
defendant “the same safeguards that surround the acceptance of a guilty plea”.
Commonwealth v. Hill, 20 Mass. App. Ct. 130, 132 (1985). See also Commonwealth v.
Castillo, 66 Mass. App. Ct. 34, 34-35 2006); Commonwealth v. Brown, 55 Mass. App. Ct.
440, 448-449 (2002). This must include an oral colloquy on the record, in which the trial
judge shall “question the defendant whether he recognizes that 1) he is entitled to confront
witnesses against him; 2) the Commonwealth has the burden of proving the offense
beyond a reasonable doubt; 3) he may be giving up the right not to incriminate himself; 4)
he is giving up the right to cross-examine; and 5) … he is acknowledging evidence likely
to lead to a finding of guilty.” Commonwealth v. Monteiro, 75 Mass. App. Ct. 280, 289
(2009). “[T]he practice of judges allowing criminal trials to be conducted on stipulated
evidence has long been disfavored… .” Commonwealth v. Castillo, 66 Mass. App. Ct. 34,
34 (2006). See also Commonwealth v. Gomez, 480 Mass. 240, 248 (2018) (stipulated
evidence trials are disfavored).
2. Stipulated testimony. The Commonwealth and the defendant
have agreed, or stipulated, that if [name of witness] were called as a
witness, they would testify that ________________. Both parties have
agreed that [name of witness] would give that testimony if called as a
witness. You should consider that testimony in the same way as if it
had been given here in court. As with all witnesses, it is for you to
determine how believable and how significant that testimony is.
A stipulation of fact leaves that fact no longer at issue and must be accepted by the jury.
By contrast, a stipulation as to testimony does not compel the jury to accept as true all the
facts within the stipulated testimony, but permits the jury to accept the stipulated evidence
in whole, in part, or not at all. Commonwealth v. Triplett, 398 Mass. 561, 570 (1986).
It is not necessary that a stipulation of fact be formally entered as an exhibit. Sierra
Marketing, Inc. v. New England Wholesale Co., 14 Mass. App. Ct. 976, 978 (1982). The
defendant’s willingness to stipulate to a fact does not preclude the Commonwealth from
introducing evidence on that issue. Commonwealth v. Andrews, 403 Mass. 441, 451
(1988).
3. Judicial Notice. The law permits me to take notice of certain
facts that are not subject to reasonable dispute. I have decided to
accept as proved the fact that _________. Therefore, you may accept
this fact as true, even though no evidence has been introduced about
it. You are not required to do so, but you may.
All factual issues should be submitted to the jury, including matters of which the judge may
take judicial notice. Commonwealth v. Kingsbury, 378 Mass. 751, 754-755 (1979) (time of
sunset); Commonwealth v. Finegan, 45 Mass. App. Ct. 921, 923 (1998). See Mass. G.
Evid. § 201(e) (2024) (“In a criminal case, the court must instruct the jury that it may or may
not accept the noticed facts as conclusive”).
The general rule in Massachusetts is that courts do not take judicial notice of regulations;
they must be put in evidence. Shafnacker v. Raymond James & Assocs., Inc., 425 Mass.
724, 730 (1997). This rule has been overridden in part by G.L. c. 30A, § 6, which requires
judicial notice of regulations published in the Code of Massachusetts Regulations.
Shafnacker, supra, 425 Mass. at 730 n.7.
4. Depositions. A deposition is a transcript of testimony that
was given out of court by a witness under oath, in response to
questions asked by either of the attorneys. You are to treat a
deposition in the same way as if the testimony had been given here in
court. As with all witnesses, it is for you to determine how believable
and how significant that testimony is.
Mass. R. Crim. P. 35(g).
5. Discrepancies in testimony. In evaluating testimony, you may
find inconsistencies or discrepancies. They may or may not cause
you to discredit such testimony. Consider whether they involve
important facts or only minor details, and whether any
inconsistencies or discrepancies result from innocent lapses of
memory or intentional falsehoods.
6. Prejudice. It would be improper for you to allow any feelings
you might have about the nature of the crime to interfere with your
decision. Any person charged with any crime is entitled to the same
presumption of innocence, and the Commonwealth has the same
burden of proving the defendant’s guilt beyond a reasonable doubt.
The fact that the prosecution is brought in the name of the
Commonwealth entitles the prosecutor to no greater consideration
and no less consideration than any other litigant, since all parties are
entitled to equal treatment before the law.
The word “verdict” comes from two Latin words meaning “to
say the truth,” and that is what the law looks to your verdict(s) to do
based solely on the evidence in the case. Justice is done when a
verdict is returned based on the evidence and the law regardless of
whether that verdict is guilty or not guilty.
Commonwealth v. Smith, 387 Mass. 900, 909-10 (1982) (verdict must be based on
evidence and not sympathy); Commonwealth v. Fitzgerald, 376 Mass. 402, 424 (1978)
(verdict may not be based on sympathy for victim or general considerations);
Commonwealth v. Clark, 292 Mass. 409, 411 (1935) (jury should be both impartial and
courageous); Commonwealth v. Anthes, 5 Gray 185, 197-98 (1855) (jury’s judgment is
conclusive of facts in case); Commonwealth v. Carney, 31 Mass. App. Ct. 250, 254 (1991)
(approving charge not to use judge’s questions or statements to determine how judge feels
case should be decided, since judge has no right to interfere with jury’s duty to find the
facts and determine where the truth lies); Commonwealth v. Ward, 28 Mass. App. Ct. 292,
296 (1990).
7. Sympathy. In many criminal cases there is an element of
sympathy which surrounds the trial. You may not permit sympathy to
affect your verdict(s).
The model instruction is drawn from Commonwealth v. Harris, 28 Mass. App. Ct. 724, 733
n.5 (1990). It may be appropriate where the trial is for a particularly emotional offense,
such as vehicular homicide.
8. Juror equality. No juror is better qualified to determine
the truth of the facts in controversy or to deliberate upon a
verdict than any other juror (or solely because of that juror’s
occupation, education, experience, or any other characteristic).
G.L. c. 234A, § 70 provides that this instruction must be given upon motion of either party
or whenever the court deems it appropriate. Commonwealth v. Oram, 17 Mass. App. Ct.
941, 942-43 (1983).
9. Judge’s questions. I want to reemphasize my instruction that
you draw no conclusions from the fact that on occasion I asked
questions of some witnesses. I intended those questions only to
clarify or expedite matters. They were not intended to suggest any
opinions on my part about your verdict or about the credibility of any
witness. You should understand that I have no opinion as to the
verdict you should render in this case.
10. Interested witnesses. The fact that a witness may have some
interest in the outcome of this case doesn't mean that the witness
isn't trying to tell you the truth as that witness recalls it or believes it
to be. But the witness’s interest is a factor that you may consider
along with all the other factors.
11. Sentencing consequences. Your function as the jury is to find
the facts and to decide whether, on those facts, the defendant is
guilty or not guilty of the crime charged. By contrast, my function as
the judge is to impose sentence if the defendant is found guilty. You
are not to consider the sentencing consequences of your verdict at
all, so please put any issues about sentencing out of your mind.
Shannon v. United States, 512 U.S. 573, 579 (1994); Rogers v. United States, 422 U.S.
35, 40 (1975).
12. Prosecution witnesses with plea agreement. In this case, you heard
the testimony of [prosecution witness] , and you heard that they are
testifying under an agreement. You should examine that witness’s
testimony with particular care. In evaluating their credibility, along
with all of the other factors I have already mentioned, you may
consider that agreement and any hopes that they may have about
receiving future benefits.
[Do not read the next two paragraphs unless evidence that the witness has agreed to
provide “truthful” testimony has been admitted.]
You are the sole judges of the credibility of a witness. The
prosecutor is not in a position to have any specialized
knowledge about whether the witness’s testimony is
truthful or not. You must disregard any suggestion that
the government or prosecutor believes or doesn’t believe
any part of their testimony.
It is up to you to determine whether the witness’s
testimony has been affected by their interest in the
outcome of the case or by any benefits that they have
received or hope to receive.
When a prosecution witness testifies under a plea agreement that is disclosed to the jury
and which makes the prosecution’s promises contingent on the witness’s testifying
truthfully, the judge must “specifically and forcefully” charge the jury to use particular care
in evaluating such testimony, in order to dissipate the vouching inherent in such an
agreement. “We do not prescribe particular words that a judge should use. We do expect,
however, that a judge will focus the jury’s attention on the particular care they must give in
evaluating testimony given pursuant to a plea agreement that is contingent on the witness's
telling the truth.” Commonwealth v. Ciampa, 406 Mass. 257, 266 (1989). “’When a
prosecution witness testifies pursuant to a plea agreement containing a promise to tell the
truth, and the jury are aware of the promise, the judge should warn the jury that the
government does not know whether the witness is telling the truth.’” See also
Commonwealth v. Shepherd, 493 Mass. 512, 530 (2024), quoting Commonwealth v.
Meuse, 423 Mass. 831, 832 (1996).
The Ciampa rule is not triggered where the prosecution’s promises were already fully
performed prior to the testimony, and there is nothing before the jury suggesting that the
plea agreement was contingent on the witness’s veracity or the Commonwealth’s
satisfaction. Commonwealth v. James, 424 Mass. 770, 785-87 (1997).
13. Incarcerated informant testimony. A witness testified in this case as
an incarcerated informant. An incarcerated informant is a witness
who was incarcerated either at the time they offered to testify, or at
the time they provided testimony, about a defendant's inculpatory
statements or actions, regardless of where or when those inculpatory
statements or actions took place.
Although the Commonwealth is permitted to present the
testimony of an incarcerated informant, you should examine the
testimony of such a witness who provides evidence against
a defendant with greater care and caution than the testimony of an
ordinary witness.
You should keep in mind that they may be looking or hoping for
some favorable treatment in the sentence, supervision, or disposition
of their own matters, and therefore their testimony may have been
influenced by their expectation of or hope for favorable treatment in
the sentence, supervision, or disposition of their own matters.
You should also keep in mind that in presenting the incarcerated
informant as a witness, the Commonwealth does not know whether
they are telling the truth. The witness's truthfulness is solely a
question for you to decide.
The factors you may consider, among others, when evaluating
the credibility of such a witness include:
• the extent to which the witness's testimony is confirmed by
other evidence;
• the extent to which the testimony contains details known only
by the perpetrator of the alleged offense;
• the extent to which the details of the testimony could be
obtained from a source other than the defendant, such as
pretrial discovery in the possession of the defendant that may
have been accessed by the witness or media coverage of the
alleged offense;
• the circumstances under which the witness initially provided
information supporting such testimony to law enforcement or a
prosecutorial official;
• whether the witness has received a benefit, or expects to receive
a benefit (including immunity from prosecution, leniency in
prosecution, leniency in sentencing, or personal advantage) in
exchange for testimony;
• any other case in which the witness testified or offered
statements and whether the witness received any promise,
inducement, or benefit in exchange for that testimony or
statement; and
• whether the witness has ever changed their testimony.
You should carefully scrutinize the testimony of such a witness
before you accept it. However, you are not required to disbelieve a
witness simply because they are an incarcerated informant. Like all
other questions of credibility, this is an issue for you to determine
based on all the evidence presented to you.
This instruction was set forth by the Supreme Judicial Court in Commonwealth v. Lacrosse,
494 Mass. 475, 495-497 (2024). It is intended to “apply to witnesses who
are incarcerated either at the time they offer to testify or at the time they provide testimony,
regardless of whether the witness has entered into a cooperation agreement.” Id. at 498.
This instruction is mandatory, unless waived by the defendant.
