Criminal, Admission to sufficient facts to warrant finding,
Plea, Conduct of government agents.
Complaint received and sworn to in the Dorchester Division
of the Boston Municipal Court Department on April 7, 2014.
A motion to withdraw a plea of guilty, filed on August 10,
2023, was heard by Erika P. Reis, J.
Alexander Conley for the defendant.
Mackenzie Slyman, Assistant District Attorney, for the
Commonwealth.
DITKOFF, J. In 2015, the defendant, Gerald Pierre,
admitted to sufficient facts in the Boston Municipal Court to
warrant a guilty finding on the offense of operating a motor
vehicle while under the influence of intoxicating liquor (OUI),
2
G. L. c. 90, ยง 24 (1) (a) (1). In 2023, after evidence came to
light of government misconduct involving the calibration of
Alcotest 9510 breathalyzer devices,1 the defendant moved to
withdraw his admission, and a judge (not the plea judge) denied
the motion. Concluding that the motion judge properly found
that the defendant had failed to demonstrate a reasonable
probability that he would not have admitted to sufficient facts
had he known of the government misconduct, we affirm.
1. Background. On April 7, 2014, at approximately
2:04 A.M., the defendant passed a State trooper while driving on
an Interstate Highway 93 on-ramp.2 The defendant was driving at
eighty-five miles per hour. The posted speed limit was fifty-
five miles per hour. The trooper stopped the defendant and
approached his vehicle. While the trooper stood at the side of
the vehicle, the defendant lifted his foot from the brake,
causing the vehicle to "jump[] forward." The trooper observed
the strong odor of an alcoholic beverage coming from the

misconduct, see Commonwealth v. Hallinan, 491 Mass. 730, 733-743
(2023).
2 The plea colloquy took place over eleven years ago and any
record of its exact content has since been destroyed in
accordance with ordinary retention procedures. See S.J.C. Rule
1:11, ยง 7, as appearing in 480 Mass. 1322 (2018). Accordingly,
we, like the parties, take the operative facts from the
application for the complaint. See Commonwealth v. Sylvester,
476 Mass. 1, 2 n.3 (2016).

defendant's vehicle and noticed the defendant's bloodshot,
glassy eyes. When the defendant spoke, his speech was slurred,
and the odor of alcohol grew stronger.
The trooper asked the defendant to step out of the vehicle.
The defendant complied with difficulty after several requests.
The defendant explained that he was coming from a bar in Boston
and that he had consumed two shots of liquor between 11:30 P.M.
and midnight. The defendant confirmed that he had no medical
problems, was not medicated, and did not suffer from any
injuries. The trooper administered five field sobriety tests to
the defendant, all of which he failed to complete to the
trooper's satisfaction.3 As a result, the trooper arrested the
defendant and placed him into his cruiser, where he again
noticed a strong odor of alcohol.
On arriving at the barracks, the defendant asked to use the
restroom, where he urinated heavily. The defendant consented to
a breathalyzer test, but during the observation period prior to
the test, he requested a cup of water, which he drank in less
than ten seconds. While waiting to take the test, the defendant
3 Specifically, in reciting the alphabet, the defendant
recited the letters "in no particular order" after L. He was
unable to count down from eighty-three to sixty-four. He
repeatedly stepped off the line, stopped walking, and used his
arms for balance in walking and turning. He fell backwards
during the one-leg stand test, and it had to be terminated for
his own safety. He failed to spell Massachusetts correctly.

fell asleep. The test revealed the defendant's blood alcohol
content to be 0.13 percent. During booking, the defendant
vomited heavily for several minutes. The trooper noted that the
defendant was in possession of a $156 nightclub receipt, as well
as the payment card associated with the receipt.
The defendant was charged with the offense of OUI, as well
as civil infractions of speeding and unsafe operation of a motor
vehicle. On September 1, 2015, the defendant admitted to
sufficient facts to warrant a guilty finding on the OUI offense.
The case was continued without a finding for one year, the
defendant's license was suspended for forty-five days, and the
defendant was placed on probation and required to complete a
program under G. L. c. 90, ยง 24D, as well as a substance use
education program. He was found not responsible for both civil
infractions. His probation was extended but ultimately
completed, and the OUI charge was dismissed on January 13, 2017.
On August 10, 2023, the defendant filed a motion to
withdraw his admission to sufficient facts. The defendant
supported his motion with his own affidavit asserting, "If I had
known that the breathalyzer results were presumptively
unreliable and inadmissible, I believe that I would not have
admitted to sufficient facts." He also presented an affidavit
from plea counsel stating, "Had I known the extent of the issues
surrounding the breath test in this matter, I would have
5
explained this to [the defendant], and advised him accordingly
as it related to his admission." After a hearing, a judge who
was not the plea judge denied the defendant's motion, finding
that he had failed to demonstrate a reasonable probability that
he would not have admitted to sufficient facts. This appeal
followed.
2. Standard of review. "A motion to vacate an admission
to sufficient facts is treated as a motion for a new trial."
Commonwealth v. Muniur M., 467 Mass. 1010, 1011 (2014). "Under
Mass. R. Crim. P. 30 (b)[, as appearing in 435 Mass. 1501
(2001)], a judge may grant a motion for a new trial any time it
appears that justice may not have been done." Commonwealth v.
Lewis, 96 Mass. App. Ct. 354, 357 (2019), quoting Commonwealth
v. Williams, 89 Mass. App. Ct. 383, 387 (2016). "We review a
judge's decision on such a motion 'for abuse of discretion or
significant error of law.'" Commonwealth v. Crump, 105 Mass.
App. Ct. 307, 312 (2025), quoting Commonwealth v. Hallinan, 491
Mass. 730, 744 (2023).
3. Application. "Under Hallinan, 491 Mass. at 731,
'defendants [charged with OUI] who pleaded guilty or who were
convicted after trial, and the evidence against whom included
breath test results from an Alcotest 9510 device last calibrated
and certified prior to April 18, 2019, . . . are entitled to a
conclusive presumption of egregious government misconduct' and
6
the exclusion of the breath test results from trial." Crump,
105 Mass. App. Ct. at 312, quoting Hallinan, supra. "Such a
defendant is permitted to rely on that presumption in a motion
to withdraw a guilty plea or for a new trial." Crump, supra.
To obtain relief, the defendant must "demonstrate a reasonable
probability that [the defendant] would not have pleaded guilty
had [the defendant] known of [the government] misconduct." Id.,
quoting Hallinan, supra at 750. "'Establishing such a
reasonable probability requires examining the totality of the
circumstances,' guided by several factors, which include
'(1) whether evidence of the government misconduct could
have detracted from the factual basis used to support the
guilty plea, (2) whether the evidence could have been used
to impeach a witness whose credibility may have been
outcome-determinative, (3) whether the evidence is
cumulative of other evidence already in the defendant's
possession, (4) whether the evidence would have influenced
counsel's recommendation as to whether to accept a
particular plea offer, and (5) whether the value of the
evidence was outweighed by the benefits of entering into
the plea agreement.'"
Crump, supra, quoting Hallinan, supra.
We agree with the defendant that an excessive focus on
whether the breathalyzer was the "crown jewel," Hallinan, 491
Mass. at 750, or, as the motion judge put it, the "center piece"
of the Commonwealth's case is not particularly helpful. As we
stated in Crump, 105 Mass. App. Ct. at 313, "While the
breathalyzer test result may have been the 'crown jewel' in
Hallinan, that is not the standard that every defendant must
7
meet." The proper focus is on whether, in light of the
disposition and the nonbreathalyzer evidence, there is a
reasonable probability that the defendant would not have
admitted to sufficient facts had he known that the breathalyzer
results were inadmissible. The regal jewelry status of the
breathalyzer results is merely one factor to be considered in
making this determination.
Here, the motion judge properly concluded that the
defendant had not established such a reasonable probability.
Even without the breathalyzer evidence, the evidence of
intoxication was overwhelming. The defendant was driving thirty
miles per hour over the speed limit on an on-ramp and failed at
first to stop his vehicle fully. He had bloodshot, glassy eyes,
slurred his speech, and gave off an odor of alcoholic beverage.
He had difficulty balancing, counting, spelling, and reciting
the alphabet. He admitted to drinking two shots of liquor, and
a nightclub receipt showing purchases of $156 was found on his
person. Once arrested, he urinated heavily, drank water
profusely, fell asleep, and then vomited for several minutes.
See Commonwealth v. Canty, 466 Mass. 535, 545 (2013)
(overwhelming evidence based on "observations of the defendant's
erratic driving, his bloodshot eyes, the odor of alcohol, his
apparent inability to put his vehicle in 'park,' his poor
performance on the field sobriety test, his admission that he
8
had been drinking alcohol, and the discovery of a half-empty
bottle of liquor in his vehicle"). Accord Commonwealth v.
Gallagher, 91 Mass. App. Ct. 385, 390-391 (2017). Contrast
Commonwealth v. Baez, 106 Mass. App. Ct. 219, 221, 224 (2025)
(not overwhelming evidence where defendant ran red light after
coming to complete stop, stepped off line during walk and turn
test, admitted to drinking alcohol, and had slurred speech and
odor of alcohol, and booking video showed defendant was alert,
attentive, and compliant with directions). In light of this
overwhelming evidence, there was no reasonable probability that
the defendant would not have admitted to sufficient facts if he
had known the breathalyzer evidence was inadmissible. See
Crump, 105 Mass. App. Ct. at 316 (listing factors this court has
considered when assessing strength of Commonwealth's case).
The ambiguous affidavits submitted by the defendant reflect
this reality. Plea counsel's affidavit recites, "Had I known
the extent of the issues surrounding the breath test in this
matter, I would have explained this to [the defendant], and
advised him accordingly as it related to his admission." The
affidavit does not "state[] unequivocally" (or even equivocally)
that plea counsel "would have advised the defendant to proceed
to trial," as was the case in Hallinan. Crump, 105 Mass. App.
Ct. at 316, quoting Hallinan, 491 Mass. at 751. It is telling
that the evidence against the defendant was so strong that plea
9
counsel could not assert that the absence of the breathalyzer
test result would have resulted in his advising a different
course of action.
As for the defendant's affidavit, it states that he
"believe[s] that [he] would not have admitted to sufficient
facts." Even setting aside the equivocal nature of that
statement, the defendant's subjective belief is not
determinative. "'[B]ecause a judge cannot evaluate whether the
defendant is telling the truth about a decision the defendant
never made,' the court is required to 'evaluate [the
defendant's] assertion under a reasonable person standard.'"
Crump, 105 Mass. App. Ct. at 317, quoting Commonwealth v.
Lavrinenko, 473 Mass. 42, 55 n.16 (2015). In light of the
overwhelming evidence against the defendant, the motion judge
here did not err in discrediting his "self-serving affidavit."
Commonwealth v. McWilliams, 473 Mass. 606, 621 (2016), quoting
Commonwealth v. Colon, 439 Mass. 519, 530 (2003).
Order denying motion to
withdraw admission to
sufficient facts affirmed.
