Judge ALLARD.

This case involves an erroneous jury instruction that was disapproved by
the Alaska Supreme Court almost five decades ago.
In the 1963 case Mann v. United States, the Fifth Circuit reversed a
criminal conviction for willfully attempting to evade paying income taxes because the
jury was given an erroneous instruction that contained an improper presumption.1 The
erroneous jury instruction stated, in relevant part:
It is reasonable to infer that a person ordinarily intends the
natural and probable consequences of acts knowingly done
or knowingly omitted. So unless the contrary appears from
the evidence, the jury may draw the inference that the
accused intended all the consequences which one standing
in like circumstances and possessing like knowledge should
reasonably have expected to result from any act knowingly
done or knowingly omitted by the accused.[2]
The Fifth Circuit pointed to two flaws in the instruction. First, the phrase,
“So unless the contrary appears from the evidence,” caused “the burden of proof [to be]
shifted from the prosecution to the defendant to prove lack of intent.”3 Second, the
instruction invited the jury “to speculate” about Mann’s intent based on what someone
“similarly situated . . . and with like knowledge” would have reasonably intended.4 Such
speculation is impermissible because the test for specific intent crimes is not what a
similarly situated person’s intent would have been, but rather what the named
defendant’s intent was.5
In the 1978 case Menard v. State, the Alaska Supreme Court held that “the
giving of the Mann instruction is error” under Alaska law, and the court “admonish[ed]

Alaska trial courts to cease using it.”6 The court nevertheless held that the error was
harmless in Menard’s case because he was acquitted of the specific intent crime and
convicted of only the general intent crime.7 In later cases, our supreme court has
reaffirmed that giving a Mann instruction is error, although it may be harmless beyond
a reasonable doubt depending on the circumstances under which it was given.8
The defendant in the current case, Rigoberto Guillermo Walker, was
charged with, inter alia, attempted murder for stabbing a woman while she was
gardening outside of her apartment. Security footage captured Walker stabbing the
woman, who was a stranger to him. The primary issue at trial was whether Walker
specifically intended to kill the woman (and was therefore guilty of attempted murder),
or whether he had recklessly caused her serious physical injury (and was therefore only
guilty of first-degree assault).
At trial, the prosecutor requested that the jury be given a Mann instruction
that included the improper burden-shifting language and the problematic reference to
“one standing in like circumstances and possessing like knowledge.” The prosecutor
claimed (erroneously) that both the Alaska Supreme Court and this Court had

reasonable doubt in Howard’s case because he was convicted of a specific intent crime);

jury instructions).

“explicitly approved” the instruction.9 He also claimed that the instruction had
repeatedly been used in the Alaska superior courts.10 Walker objected to the instruction.
The superior court took the matter under advisement and subsequently
gave the instruction over Walker’s objection. In closing argument, the prosecutor read

Although the Alaska Supreme Court’s disapproval of the Mann instruction is clear
from its caselaw, we note that there are a number of potential sources of confusion that
may have led to the prosecutor’s mistake. First, it appears that the prosecutor may have
misread cases that found the Mann instruction harmless as suggesting that the instruction
was not actually error. Second, there used to be a pattern jury instruction that was very
similar to the first part of the Mann instruction — “It is reasonable to infer that a person
ordinarily intends the natural and probable consequences of acts knowingly done or
knowingly omitted” — but did not include the explicit burden shifting provision or the
other “similarly situated” language that had been identified as problematic by the Fifth
Circuit in Mann. This pattern instruction was replaced a number of years ago with a
different pattern instruction on state of mind. See Alaska Criminal Pattern Instruction 1.15
(2025). We also recently disapproved of this former pattern instruction on the grounds that
the instruction “undermines the legal distinction between negligence or recklessness, on
the one hand, and intent (conscious objective) on the other.” Burton-Hill v. State, 569 P.3d
1, 44-45 (Alaska App. 2025).
Prior to that disapproval, however, we had issued decisions that approved the former
pattern instruction against various challenges. See, e.g., Kangas v. State, 463 P.3d 189,
192-95 (Alaska App. 2020); Gargan v. State, 805 P.2d 998, 1005 (Alaska App. 1991).
Notably, in Kangas and Gargan, we mistakenly stated that the Alaska Supreme Court had
“approved” the challenged instruction, citing to the supreme court’s opinion on rehearing
in Calantas v. State, 608 P.2d 34 (Alaska 1980) (opinion on rehearing). See Kangas, 463
P.3d at 192; Gargan, 805 P.2d at 1005. This was incorrect. The instruction used in Calantas
was a true Mann instruction that included the improper burden shifting provision and the
problematic reference to “one standing in like circumstances and possessing like
knowledge.” Calantas, 599 P.2d at 150. Moreover, the Alaska Supreme Court was clear in
its initial Calantas decision that it had “condemned” the use of the Mann instruction, even
though it found its use harmless in that particular case. Id. at 150-51.

As we noted in the footnote above, the prosecutor may have been confused about
the difference between a Mann instruction and a former pattern jury instruction, which was
itself replaced a number of years ago and recently disapproved of by this Court in Burton-
Hill, 569 P.3d at 44-45.

the instruction to the jury and used it to argue that Walker intended to kill the woman
he stabbed. The jury convicted Walker of attempted murder.11
On appeal, the State concedes that “the Alaska Supreme Court [has]
resoundingly disapproved the use of a Mann instruction” and that its use in Walker’s
case was error. These concessions are well-founded.12 The State argues, however, that
the error was harmless beyond a reasonable doubt because the jury was otherwise
properly instructed on the State’s burden of proof, and because the evidence of Walker’s
intent to kill was strong. We disagree that the error was harmless beyond a reasonable
doubt.13
In Menard, our supreme court found that giving the Mann instruction was
harmless beyond a reasonable doubt because “the jury acquitted Menard of the specific
intent charge.”14 Conversely, in Howard v. State, the supreme court held that giving the

AS 11.41.100(a)(1)(A) & AS 11.31.100(a). The jury also convicted Walker of one
count each of first-, second-, third-, and fourth-degree assault in violation of
AS 11.41.200(a)(1), AS 11.41.210(a)(1), AS 11.41.220(a)(1)(B), and AS 11.41.230(a)(1),
respectively. These guilty verdicts merged with the attempted murder conviction at
sentencing. The jury acquitted Walker of the assault charges related to the eyewitnesses.

See Marks v. State, 496 P.2d 66, 67-68 (Alaska 1972) (holding that appellate courts
must independently assess whether the State’s concession of error in a criminal case is
well-founded).

See United States v. Garrett, 574 F.2d 778, 783 (3d Cir. 1978) (noting that use of a
Mann instruction “will be deemed error, and convictions obtained in trials in which the
instruction is given will be reversed, except in those ‘very extraordinary circumstances [in
which] the error may be found so inconsequential as to avoid the necessity of reversal on
appeal’”) (quoting United States v. Fioravanti, 412 F.2d 407, 420 (3d Cir. 1969)); see also
Cohen v. United States, 378 F.2d 751, 755 (9th Cir. 1987) (noting that the use of a Mann
instruction “is an invitation to reversal”).

Menard v. State, 578 P.2d 966, 970 (Alaska 1978); see also Carman v. State,
602 P.2d 1255, 1259-60 (Alaska 1979) (holding that the giving of the Mann instruction
was harmless beyond a reasonable doubt in part because “whether Carman possessed the
specific intent to steal did not become one of singular importance in [the] case”).

–5– 2808
Mann instruction was not harmless beyond a reasonable doubt in part because Howard,
unlike Menard, had been convicted of a specific intent crime.15
Here, Walker was convicted of a specific intent crime in a trial where the
sole contested issue in relation to the attempted murder charge was whether Walker
acted with the specific intent to kill.16 Moreover, the potential prejudice caused by the
Mann instruction was amplified by the fact that the prosecutor expressly referred to the
instruction in closing argument and used the instruction to argue the State’s theory of
specific intent. Under these circumstances, we cannot say that the giving of the Mann
instruction — an instruction condemned by the Alaska Supreme Court nearly five
decades ago — was harmless beyond a reasonable doubt.
The judgment of the superior court is REVERSED. On remand, the State
may elect to retry Walker on the attempted murder charge with a properly instructed
jury. If the State elects not to retry Walker on the attempted murder charge, judgment
should be entered on the first-degree assault conviction and Walker should be
resentenced accordingly.

P.2d 88, 91 n.5 (Alaska 1982) (noting that the Mann instruction in Howard was prejudicial
because the defendant was convicted of a specific intent crime, while the use of the Mann
instruction in Menard was “largely irrelevant” because the defendant was only convicted
of a general intent crime), overruled on other grounds by Young v. State, 374 P.3d 395
(Alaska 2016).

See Anderson v. State, 372 P.3d 263, 264-65 (Alaska 2016) (emphasizing that
Alaska follows the “effect-on-the-jury” approach rather than the “guilt-based” approach to
determine whether a constitutional error is harmless beyond a reasonable doubt).
