Commonwealth v. Guardado, 493 Mass. 1

In June 2019 Guardado was indicted on firearm-related charges (possession of a firearm, a loaded firearm, ammunition, and large-capacity feeding devices).
At trial the judge omitted absence of a firearms license from the elements the Commonwealth had to prove; Guardado did not object at trial and was convicted in June 2021.
While the case was pending on appeal, the U.S. Supreme Court decided Bruen, which led this court in Commonwealth v. Guardado, 491 Mass. 666 (2023) (Guardado I), to hold that absence of a license is an essential element of unlawful possession offenses.
In Guardado I this court vacated Guardado’s convictions and ordered entry of judgments of not guilty on the firearm, loaded-firearm, and ammunition counts, concluding the jury instruction error relieved the Commonwealth of proving an element.
The Commonwealth moved for reconsideration, arguing double jeopardy does not bar retrial because the insufficiency stemmed from an intervening change in law (Bruen) and the Commonwealth had no reason under then-prevailing precedent to offer license evidence.
On reconsideration the court withdrew the prior remand for acquittal and ordered a new trial on the affected indictments, holding retrial is permitted where insufficiency results from a posttrial, controlling change in law that the prosecution could not reasonably have anticipated.

Issue	Commonwealth's Argument	Guardado's Argument	Held
Whether absence of a firearms license is an essential element	Bruen requires license absence to be an element (as held in Guardado I); but remedy should allow retrial	License absence is an essential element and insufficiency requires acquittal under double jeopardy	Court applied Bruen (license is an element) but held retrial is permitted on remedy grounds
Whether double jeopardy bars retrial when evidence at trial was insufficient only because of an intervening change in law	Double jeopardy does not bar retrial where the prosecution had no reason under then-prevailing law to present evidence of the omitted element	Double jeopardy bars retrial because current law shows the evidence presented was insufficient	Court: retrial permitted — insufficiency was due to posttrial legal change, not a failure by the Commonwealth to present evidence it then needed to prove
Whether precedents like Munoz/Beal require acquittal here	Those cases are distinguishable; here the law changed after trial due to Bruen so the Commonwealth deserves a first opportunity to prove the element	Munoz and Beal show acquittal is required where the Commonwealth failed to prove an element contrary to existing law	Court distinguished Munoz and Beal and declined to require acquittal; remanded for new trial
