case prior to her retirement.

BUDD, J. We are asked to decide whether, in a jury trial
of an operating a motor vehicle while under the influence (OUI)
case, a trial judge may properly give a jury instruction that
specifically mentions the absence of breathalyzer or other
alcohol-test evidence. We conclude that the judge should not
give such an instruction unless the defendant requests it.2
In this case, the jury were instructed about the absence of
alcohol-test evidence in the judge's final instructions over the
defendant's objection. We conclude that giving the objected-to
charge constituted error and that, in the circumstances of this
case, the error was prejudicial. Accordingly, we vacate the
defendant's conviction and remand for a new trial.3
Background. The defendant was charged by complaint with
one count of OUI, G. L. c. 90, § 24 (1) (a) (1), and twice faced
trial on this complaint before a jury in the Marlborough
Division of the District Court Department. The first, in
January, 2016, ended in a mistrial. The second, in March, 2016,
resulted in a conviction. We summarize the facts as the jury

It is possible that a rare case could justify giving such
an instruction over a defendant's objection, but we have trouble
imagining such a scenario.

Public Counsel Services, and the Massachusetts Association of

could have found them at the second trial,4 reserving additional
details for later discussion.
On February 13, 2015, at around 2 A.M., a Marlborough
police officer patrolling the Main Street area noticed a Ford
Explorer being driven with a broken taillight. The officer
followed the vehicle for approximately five to ten minutes.
During that time, the officer witnessed the vehicle cross the
double yellow line in a "jerking motion" to avoid hitting a snow
bank, and later saw the vehicle cross the double yellow line
again while executing a turn.
The officer then stopped the vehicle at the intersection of
Union Street and Stevens Street. Upon approaching the vehicle,
the officer observed the defendant in the driver's seat with
"bloodshot glassy eyes, slurred speech and a distinct odor of
alcohol coming from his breath when he spoke." The defendant
initially told the officer he was coming from a sandwich shop on
Main Street. When the officer replied that the shop closed much
earlier in the evening, the defendant admitted that he had been
at a nightclub where he had consumed "a few" drinks. The
defendant gave "delayed" responses to several of the officer's
questions.
The officer then asked the defendant to step out of the

vehicle and walk back to the officer's patrol vehicle. During
this walk, the defendant used his own vehicle "for balance."
Another officer at the scene testified that the defendant was
"swaying" and "unsteady on his feet." The defendant was placed
under arrest and transported to the Marlborough police station
for booking.
At the station, the defendant "immediately" fell asleep in
a holding cell. During the booking procedure, the officer again
noticed the smell of alcohol on the defendant's breath and had
to repeat questions multiple times before the defendant
responded. At one point, the defendant was permitted to use his
cellular telephone, but instead he sat "just staring" at his
telephone and said that it would not turn on. The officer
allowed the defendant to use the station's telephone, and
explained to the defendant how to dial an outside number. The
defendant appeared unable to understand this, so the officer
dialed the number for him.
There was no mention in the trial evidence of the lack of a
breathalyzer test or other alcohol-test evidence. Nevertheless,
the judge instructed the jury, over the defendant's objection,
not to consider the absence of breathalyzer tests, field
sobriety tests, or blood tests.5 The judge explained that he

believed this instruction was warranted, in part, because the
jury in the first trial had asked a question about the absence
of breathalyzer evidence before failing to reach a verdict.
At the second trial, the jury found the defendant guilty.
The defendant filed a timely notice of appeal, and we allowed
his application for direct appellate review.
Discussion. Primarily, the defendant claims that the trial
judge erred by instructing the jury, over objection, that they
should disregard the lack of evidence of a breathalyzer test,
blood test, or field sobriety test.6 Generally, trial judges
have "considerable discretion in framing jury instructions."
Commonwealth v. Kelly, 470 Mass. 682, 688 (2015). However,
when, as here, a defendant raises a timely objection to an
instruction, we review for prejudicial error, conducting a two-
"Now, you may have noticed that there was no evidence
of any breath test, blood test, or field sobriety test
introduced in this case. You are not to mention or
consider in any way whatsoever during your deliberations
either for or against either side that there was no such
evidence introduced in this case. Do not consider it in
any way at all. Do not mention it at all during your
deliberations. Put it completely out of your minds."

The defendant also claims error in certain statements the
prosecutor made during his closing argument. Because our
resolution of the jury instruction issue requires a new trial,
we do not reach the closing argument claim. However, to the
extent it is helpful at retrial, we note that there appeared to
be scant, if any, evidentiary support for the prosecutor's
statement that "the booking station was filled with the odor of
alcohol" due to the defendant's presence.

part test that asks (1) whether the instruction was legally
erroneous, and, if so, (2) whether that error was prejudicial.
Id. at 687-688, and cases cited.
The challenged instruction was a modified version of an
instruction upheld in Commonwealth v. Downs, 53 Mass. App. Ct.
195, 198 (2001).7 In Downs, the Appeals Court distinguished
Opinion of the Justices, 412 Mass. 1201 (1992), and Commonwealth
v. Zevitas, 418 Mass. 677 (1994), in both of which this court
held that reference to possible reasons for the absence of
breathalyzer evidence violated a defendant's right against self-
incrimination under art. 12 of the Massachusetts Declaration of
Rights. See Downs, supra at 199.
In Opinion of the Justices, 412 Mass. at 1202, this court
was asked to opine on the constitutionality of a Senate bill
proposing the admission of evidence in a criminal proceeding of
a defendant's refusal to submit to a chemical test or
breathalyzer. The court determined that admitting such evidence
would violate art. 12, as it would be tantamount to providing

The specific instruction at issue in Downs was as follows:
"You are not to mention or consider in anyway
whatsoever, either for or against either side, that there
is no evidence of a breathalyzer. Do not consider that in
any way. Do not mention it. And put it completely out of
your mind."
Commonwealth v. Downs, 53 Mass. App. Ct. 195, 198 (2001).

the jury with the defendant's self-incriminating evidence, i.e.,
that he refused to submit to testing because he believed it
would show he had too much to drink. Id. at 1209, 1211.
In Zevitas, 418 Mass. at 681-682, the defendant challenged
a jury instruction stating, in part, that "a person has a legal
right either to take or not to take" a breathalyzer test, and
that "[i]n any particular situation, there may be a number of
reasons why a person would not take such a test; and there may
be a number of reasons why such a test was not administered by
the police." The court held that such an instruction, although
at the time mandated by statute,8 violated the defendant's art.
12 rights insofar as it invited speculation that the defendant
failed to take a breathalyzer because he feared the results
would be unfavorable. Id. at 683-684.
In Downs, 53 Mass. App. Ct. at 199-200, the Appeals Court
reasoned that, because the instruction at issue made "no mention
either of a defendant's legal right to refuse to take the

See G. L. c. 90, § 24 (1) (e), as amended through
St. 1994, c. 25, § 5 ("When there is no [alcohol-test] evidence
presented at a civil or criminal proceeding . . . the presiding
judge at a trial before a jury shall include in his instructions
to the jury . . . that a person has a legal right to take or not
take such a test; that there may be a number of reasons why a
person would or would not take such a test; that there may be a
number of reasons why such test was not administered; that there
shall be no speculation as to the reason for the absence of the
test and no inference can be drawn from the fact that there was
no evidence of a blood alcohol test . . ."). See also St. 2003,
c. 28, § 3 (striking out above language).

breathalyzer or the possible reasons for any refusal," it
avoided the art. 12 obstacles identified in Opinion of the
Justices and Zevitas.
The defendant disagrees with that logic and asks us to
reject the reasoning of Downs. He argues, in effect, that all
so-called Downs instructions suffer from the same art. 12 defect
found in Opinion of the Justices and Zevitas. The Commonwealth,
on the other hand, urges us to embrace the distinction
articulated in Downs and hold that a Downs instruction
adequately protects both the Commonwealth and defendants against
jury speculation without inappropriately implicating a
defendant's art. 12 rights.
These arguments boil down to competing claims about who is
most at risk of being harmed if the jury fail to follow
instructions. In this way, both arguments diverge from a long
tradition of appellate courts presuming that juries can and will
follow a judge's instructions. See, e.g., Commonwealth v.
Andrade, 468 Mass. 543, 549 (2014); Commonwealth v. Cline, 213
Mass. 225, 227 (1913). The Commonwealth's argument assumes that
a breathalyzer-specific instruction is necessary because,
without it, the jury will speculate about the absence of
breathalyzer evidence, contrary to the judge's more general
directive to base their verdict solely on the evidence. See
Instruction 2.120 of the Criminal Model Jury Instructions for
9
Use in the District Court (2016) ("You are not to decide this
case based on what you may have read or heard outside of this
courtroom. You are not to engage in any guesswork about any
unanswered questions that remain in your mind, or to speculate
about what the 'real' facts might or might not have been"). The
Downs case itself makes a similar assumption. See Downs, 53
Mass. App. Ct. at 199 ("without some form of a limiting
instruction concerning the breathalyzer, a jury very well could
rely upon their common knowledge and engage in the same
speculation invited by the erroneous instruction [rejected in
Zevitas]").
Similarly, the defendant claims that giving a Downs
instruction unnecessarily introduces the specter of refusal
evidence into the jury room and will have the opposite of the
intended effect, that is, it will cause the jury specifically to
focus on the absence of breathalyzer evidence. And, indeed, our
decision in Zevitas, 418 Mass. at 684, was structured around our
assessment of the risk that juries may not always hew to a
judge's instructions to refrain from speculating about matters
not in evidence.
We have encountered a variation of this problem before,
when asked to decide whether (and, if so, when) a judge should
instruct a jury about a defendant's choice not to testify at
trial. See Commonwealth v. Rivera, 441 Mass. 358, 370-371
10
(2004); Commonwealth v. Buiel, 391 Mass. 744, 746-747 (1984).
In Buiel, supra at 746, we remarked that it is "difficult to
determine" whether an instruction about the defendant's election
not to testify "is beneficial to a particular defendant or to
defendants as a group." On the one hand, such an instruction
"warns the jury against drawing inferences adverse to the
defendant from his not testifying." Id. at 746-747. On the
other, it "may focus the jury's attention on the question why
the defendant decided not to assist the jury in their fact-
finding function."9 Id. at 747. In light of that difficulty, we
announced the prospective and "not constitutionally based" rule
that it would be "reversible error if a judge instructs the jury
concerning a defendant's right not to testify when the defendant
has requested that no such instruction be given." Id. at 746,
747.
In Rivera, we reconsidered the rigidity of this rule, but
not its basic thrust. We said that it would no longer be "per
9
As the amici point out, this notion draws strong support
from common sense and experience. See F.M. Dostoevsky, Winter
Notes on Summer Impressions 112 (R.L. Renfield trans., 1955)
("Try this experiment on yourself: try not to think of a polar
bear and you will see that the cursed animal keeps returning to
your mind"). Psychologists refer to this phenomenon as "ironic"
mental processing and posit that an instruction not to think
about something can trigger a mental monitoring process to guard
against the forbidden thought; this monitoring process, in turn,
may increase the frequency and power of the forbidden thought.
See Lieberman & Arndt, Understanding the Limits of Limiting
Instructions, 6 Psych., Pub. Pol'y & L. 677, 697-700 (2000).
11
se reversible error" for a judge to give an instruction about
the defendant not testifying, but that the instruction, when
objected to, would be subject to review for prejudicial error.
Rivera, 441 Mass. at 370-371 & n.9. Nevertheless, "[w]e
remain[ed] of the view that judges should not give the
instruction when asked not to do so." Id. at 371 n.9.
We believe that similar logic applies here and compels a
similar conclusion with respect to an objected-to instruction
about the lack of alcohol-test evidence in an OUI case. The
challenge here, as in Buiel and Rivera, is rooted in the
defendant's art. 12 protection against self-incrimination.
Although a Downs instruction does not implicate a defendant's
self-incrimination rights as directly as an instruction about a
defendant's choice not to testify, it evokes similar concerns.
See Zevitas, 418 Mass. at 683-684; Downs, 53 Mass. App. Ct. at
199-200. Also, as in Buiel, 391 Mass. at 746, we find it
difficult to assess whether a Downs-type instruction "is
beneficial to a particular defendant or to defendants as a
group." Doing so would require us to engage in a series of
generalizations about defendants in OUI cases, make assumptions
about whether and when juries are able to follow a judge's
instructions, and speculate ourselves about where the jury's
speculation may lead -- all without the benefit of any
supporting empirical evidence. The same basic problems are
12
inherent in assessing the Commonwealth's claim that it, too, may
be harmed by the lack of a Downs instruction.10
We are persuaded instead that the simpler and safer
approach is to leave such an instruction to the defendant's
choice. This approach has the benefit of simplicity because it
reaffirms our traditional presumption that the jury will heed
the judge's general instruction not to speculate about evidence
10
Along these lines, we agree with the dissent that a
trial, at its core, is a search for the truth. See post at .
But we have a difference of opinion as to how to best achieve
that goal. The dissent believes that giving a jury instruction
that specifically mentions the absence of breathalyzer evidence
is necessary to ensure that the jury, in fact, do not consider a
missing breathalyzer test. See id. at . As discussed below,
we do not agree that such an instruction is necessary to stave
off speculation by the jury. Even so, we acknowledge that such
an instruction very well may be effective. However, there is
another possibility: that such a targeted instruction
introduces the idea of missing breathalyzer evidence into the
jury room, and, as a result, prompts the jury to wonder about
the missing breathalyzer evidence and do the opposite of what
they have been instructed to do. See note 9, supra, and
accompanying text. Because this latter path risks encroaching
upon a defendant's constitutional right not to incriminate
himself or herself, we believe the decision whether the jury
receive such an instruction should rest with the defendant, not
the Commonwealth or the court. See Commonwealth v. Buiel, 391
Mass. 744, 747 (1984).
To borrow the dissent's metaphor, we do not disagree that
the jury might find an "oar," in the form of a more specific
jury instruction, helpful in navigating the legal waters of an
OUI case. Post at note 1. But we do not think it wise to
present the jury with such a device in a case like this, where,
for the reasons discussed in the text, the jury may use it so
readily to paddle into restricted waters -- i.e., a defendant's
art. 12 rights -- at least not without the defendant's consent,
as in Buiel, 391 Mass. at 747, and Commonwealth v. Rivera, 441
Mass. 358, 371 n.9 (2004).
13
not before them. By adhering to that presumption from the
outset, the need for the breathalyzer-specific instruction
approved of in Downs dissipates.11
We also agree with the defendant that in Opinion of the
Justices and Zevitas we have suggested a tendency to err on the
side of caution when it comes to encroaching upon a defendant's
constitutional right not to incriminate himself or herself. In
those cases, we expressed concern that the introduction of
refusal evidence (Opinion of the Justices) or instructions
highlighting, however indirectly, the possibility of refusal
(Zevitas) would nudge the jury toward using refusal evidence
against a defendant in violation of his or her art. 12 rights.
See Zevitas, 418 Mass. at 684; Opinion of the Justices, 412
Mass. at 1211. Although this risk may be relatively low, its
potential consequences are quite serious. See Commonwealth v.
11
The dissent does not adequately explain why, if it is
presumed that the jury follow the judge's instructions, there is
any need for a Downs instruction in the first place. If we
presume the jury follow the judge's instructions, that
presumption should apply equally to the judge's general
instruction not to speculate about matters not in evidence.
This would protect both the Commonwealth and the defendant from
speculation about the absence of breathalyzer evidence without
creating the possibility of inducing speculation by specifically
mentioning the absence of breathalyzer evidence. To the extent
the dissent is concerned about jurors speculating based on their
collective knowledge, from outside the court room, about
breathalyzer testing, we have rejected a similar supposition
when called upon to examine the need, or lack thereof, for so-
called "CSI" instructions. See Commonwealth v. Vuthy Seng, 456
Mass. 490, 503-504 (2010).
14
Sneed, 376 Mass. 867, 871 (1978) ("Even an unintended suggestion
that might induce the jury to draw an unfavorable inference
[based on defendant's right not to incriminate himself] is
error"). And, of course, leading the jury down an inappropriate
path is precisely the opposite of what jury instructions are
supposed to do. Cf. King v. Trustees of Boston Univ., 420 Mass.
52, 64 (1995), quoting Pfeiffer v. Salas, 360 Mass. 93, 100-101
(1971) (jury instructions "should be full, fair and clear as to
the issues to be decided by the jury, the rules to be followed
by the jury in deciding the facts, and the law they are to apply
to the facts found").
Accordingly, we conclude that typically a defendant should
be able to elect whether the jury are instructed about the
absence of alcohol-test evidence. See Buiel, 391 Mass. at 746-
747. We emphasize that this conclusion, although rooted in
constitutional concerns, is not a new constitutional rule
requiring retroactive application.12 See Rivera, 441 Mass. at
370; Buiel, supra at 747. Rather, as an exercise of our
superintendence power, we conclude that, as a matter of
12
Although Commonwealth v. Zevitas, 418 Mass. 677 (1994),
announced a constitutionally based rule requiring retroactive
application, see Commonwealth v. D'Agostino, 421 Mass. 281, 286-
287 (1995), this case is distinguishable because the challenged
instruction here, unlike in Zevitas, supra at 682, does not
specifically mention the possibility of refusing a breathalyzer
test. We reiterate that our decision today is procedural only
and has only prospective application.
15
procedure, the better practice is for a judge to refrain from
giving a Downs-type instruction absent a request by the
defendant or some rare set of facts that specifically directs
the jury's attention to the absence of alcohol-test evidence.13
Cf. Commonwealth v. DiGiambattista, 442 Mass. 423, 444-445, 447–
448 (2004) (using superintendence power to regulate presentation
of evidence at trial in requiring, under certain circumstances,
jury instructions regarding defendant's unrecorded statement to
police).
In this case, the instruction regarding alcohol-test
evidence was given over the defendant's objection. Based on our
analysis today, this was error.14 Because the defendant objected
at trial and argued for this rule on direct appeal, he should
have the benefit of this decision, which otherwise shall apply
only prospectively. See Commonwealth v. Adjutant, 443 Mass.
649, 667 (2005). Accordingly, we review for prejudicial error.
13
Further, when a jury ask a question about the absence of
alcohol-test evidence, as occurred in the defendant's first
trial, we think it is the better practice to simply reiterate
the general instruction not to speculate about matters not in
evidence and, to the extent possible, refrain from reinforcing
the jury's focus on items not in evidence by mentioning the lack
of alcohol-test evidence.
14
We understand why the trial judge in the defendant's
second trial chose to give the instruction that he did, given
the Appeals Court's ruling in Downs. However, in light of our
decision today, which differs from that of the Appeals Court in
Downs, the instruction constituted legal error.
16
Commonwealth v. Allen, 474 Mass. 162, 168 (2016). This means
that we "inquire[] whether there is a reasonable possibility
that the error might have contributed to the jury's verdict."
Commonwealth v. Alphas, 430 Mass. 8, 23 (1999) (Greaney, J.,
concurring). "An error is not prejudicial if it 'did not
influence the jury, or had but very slight effect.'"
Commonwealth v. Cruz, 445 Mass. 589, 591 (2005), quoting
Commonwealth v. Flebotte, 417 Mass. 348, 353 (1994).
Here, the evidence of impaired operation was far from
overwhelming. For example, the defendant offered a plausible
explanation that his first crossing of the double yellow line
was necessary to avoid hitting a snow bank in the roadway, and
that the second was a relatively brief and minor infraction in
the course of making a left-hand turn. He also plausibly
suggested that, as he walked back to the arresting officer's
cruiser, he used his own vehicle to steady himself not because
he was impaired, but as a caution against ice on a cold February
night. Moreover, the erroneous remarks at issue here "f[e]ll
from the judge himself," and thereby likely had a more damaging
effect on the jury. See Zevitas, 418 Mass. at 684, quoting
Commonwealth v. Goulet, 374 Mass. 404, 414 (1978). Under these
circumstances, we cannot fairly say that "the jury would have
inevitably reached the same result if the judge had omitted the
challenged instruction." Buiel, 391 Mass. at 747.
17
Conclusion. For the reasons discussed, the defendant's
conviction is vacated and the case is remanded for a new trial.
So ordered.
LOWY, J. (dissenting, with whom Gaziano and Cypher, JJ.,
join). Today the court recognizes that a defendant should be
able to remove speculation regarding the absence of breathalyzer
evidence from a trial on a charge of operating a motor vehicle
while under the influence of alcohol (OUI) by requesting an
instruction pursuant to Commonwealth v. Downs, 53 Mass. App. Ct.
195, 198 (2001). I agree. However, because I feel that the
Commonwealth should also be able to remove such speculation by
requesting the same instruction, I respectfully dissent.
A trial serves many purposes, but at its core, it is a
search for truth. When jurors find facts, not from a fair
consideration of the evidence, but rather based upon
bewilderment as to why no evidence of a breathalyzer test was
introduced, confidence in trial by jury in some measure
incrementally dissipates. Perhaps one might respond: jurors
are instructed to apply the facts to the law as given and not to
speculate as to any unanswered questions they may have. A
general instruction not to speculate is ineffective in the face
of common knowledge of the breathalyzer test. The beauty and
simplicity of the Downs instruction is that it thoroughly
removes speculation regarding the absence of breathalyzer
evidence without prejudicing the defendant or the Commonwealth.
In Downs, 53 Mass. App. Ct. at 199, the Appeals Court held
that the jury instruction complained of here did not violate the
2
defendant's privilege against self-incrimination under art. 12
of the Massachusetts Declaration of Rights, noting that the jury
"were simply but forcefully instructed that they were not to
think about or otherwise consider the fact that no evidence was
offered concerning the breathalyzer." The Appeals Court also
pointed out the danger of allowing the specter of the
breathalyzer to hang over the trial and that an OUI jury trial
without any reference whatsoever to breathalyzer testing risks
unfair prejudice to a defendant and the Commonwealth. Id. at
199 & n.2. That is to say, without some form of a limiting
instruction concerning the breathalyzer, a jury very well could
rely upon their common knowledge and engage in improper
speculation.
Indeed, this type of speculation appears to have occurred
at the defendant's first trial, which resulted in a mistrial.
There, the jury asked the judge, "Are we allowed to ask: 'Why
there are no tests?' eg. Breathalyzer or blood test?" Although
that record is not before us, presumably the jury were given the
general instruction that they were to decide the case on the
evidence presented to them and not to speculate on anything not
in evidence. Yet they still engaged in speculation.
The Downs instruction prevents precisely this kind of
speculation and rests on the long-standing principle that the
3
jury are presumed to follow the judge's instructions.1 See
Commonwealth v. Cline, 213 Mass. 225, 227 (1913). This
principle lies at the very heart of our justice system:
"Unless we proceed on the basis that the jury will
follow the court's instructions where those instructions
are clear and the circumstances are such that the jury can
reasonably be expected to follow them, the jury system
makes little sense. Based on faith that the jury will
endeavor to follow the court's instructions, our system of
jury trial has produced one of the most valuable and
practical mechanisms in human experience for dispensing
substantial justice."
Delli Paoli v. United States, 352 U.S. 232, 242 (1957), rev'd on
other grounds by Bruton v. United States, 391 U.S. 123, 126
(1968).
1
The court concludes that the presumption that the jury
follow instructions should apply equally to the general
instruction not to speculate as it does to the specific Downs
instruction. The existence of a general instruction cannot,
however, preclude the possibility that a specific instruction is
needed. For example, in a trial where autopsy photographs are
introduced, a general instruction that jurors should disregard
emotion and sympathy when reaching a verdict does not preclude a
judge from specifically instructing the jury on the proper use
of such photographs. See Commonwealth v. Lawrence, 404 Mass.
378, 390 (1989). Just because we send a jury navigating a rough
sea of complex legal issues a life raft (i.e., general jury
instructions) does not mean we should not also give them an oar
(i.e., a specific instruction or Downs instruction).
Further, a general instruction not to speculate may be
ineffective in the face of jurors' likely knowledge of the
scientific capability to measure the amount of alcohol in an
individual's blood. Cf. Commonwealth v. Gray, 465 Mass. 330,
339-340 (2013) (not abuse of discretion "for voir dire questions
designed to counter any 'CSI effect'" in certain circumstances).
4
For more than fifteen years, Downs has been the law of this
Commonwealth. See Commonwealth v. Gibson, 82 Mass. App. Ct.
834, 836 (2012). Nothing in this record suggests that the
decision was in any way unsound. Because I believe the best way
to prevent prejudice to the defendant and the Commonwealth is to
allow either party to remove the threat of speculation from jury
deliberations, I respectfully dissent.
