California Supreme Court Rulings Open the Door on Gang Enhancements and Three Strikes

Last week, the California Supreme Court issued two landmark rulings that could have far-reaching consequences for people serving time under gang enhancements and the state’s “three strikes” law. These decisions don’t just tweak legal technicalities — they could open a real pathway for thousands of incarcerated people to challenge sentences that were stacked higher and heavier because of gang allegations.

What Happened

Both rulings turned on AB333, a 2021 law that raised the bar for prosecutors seeking to prove gang involvement. Before AB333, prosecutors could argue that almost anything done “for the benefit of the gang” — even something as vague as reputational clout — was enough to slap on a gang enhancement. These enhancements could add years, even decades, to a sentence, and in many cases, they triggered California’s three strikes law, leading to life sentences.

AB333 changed that. Now, prosecutors must show more than reputational benefit — the alleged gang activity has to provide a material benefit to the group, such as financial gain. Crucially, the law is retroactive, which means it applies to past convictions too.

Two Major Decisions

The Supreme Court applied AB333 in two separate cases last week:

• The Three Strikes Case (4–3 decision):
  In a close ruling, the Court agreed with two incarcerated men who argued that their 2015 gang enhancements could no longer be counted as “strikes” under the stricter standard of AB333. Because their appeals were still pending when the law went into effect, the Court said those prior gang convictions didn’t hold up. One of the men also had a 2020 attempted murder case that, combined with the earlier enhancements, had set him on course for a life sentence. With the 2015 enhancement vacated, his sentence now looks very different — potentially removing the “third strike” that locked him into a lifetime behind bars.

• The Death Penalty Case (5–2 decision):
  In another case, the Court struck down the gang enhancement attached to a 2003 murder and attempted murder conviction. The justices upheld the underlying convictions, but they reversed the death sentence and sent the case back to Orange County for re-sentencing. Why? Because the only evidence of gang motivation was a detective’s testimony that the shooting was done for reputational benefit. Under AB333, that’s no longer enough.

Why This Matters

This is a huge deal. For decades, gang enhancements have been used to ratchet up sentences, often based on thin evidence and vague theories of “benefit to a gang.” These enhancements have hit Black and Brown communities the hardest, feeding California’s over-incarceration crisis.

The rulings don’t automatically free anyone. Each person will still need to petition the courts and argue their case. But the Supreme Court has now set a clear precedent: past gang enhancements must be re-examined under AB333’s stricter standards.

A Divided Court

The decisions weren’t unanimous. In the 4–3 case, a dissenting justice warned that applying AB333 retroactively would make it “virtually impossible” to prove past gang enhancements. Her objection wasn’t just legal — it was political. She essentially admitted that if the law is applied the way it’s written, thousands of people may see their enhancements vacated. In other words, the dissent was worried that doing the right thing under the law would undo years of harsh sentencing.

What Comes Next

It’s too soon to know the full impact, but here’s what we do know:

• AB333 is retroactive. That means anyone with a gang enhancement on their record should at least explore whether this ruling gives them a pathway to relief.

• Three strikes cases could be transformed. If a past gang enhancement was counted as a strike, and it no longer holds under AB333, a life sentence might not stand.

• Death penalty cases are in play. Even in the most severe cases, like the one just reversed, gang enhancements can no longer rest on the weak “reputation alone” standard.

The California Supreme Court has made it clear: the old way of slapping on gang enhancements doesn’t hold up anymore. For thousands of people, this could be the crack in the wall they’ve been waiting for.
