In brief

Where it stands
Decided

Decided 5-4 · June 24, 2019 · Opinion by Justice Gorsuch

What it’s about
The Supreme Court ruled that the federal law’s definition of a “crime of violence” for firearm charges is unconstitutionally vague, meaning it is too unclear to enforce under the Constitution.
Who it affects
The decision means the challenged definition cannot be used as written in the federal firearm provision, which can add substantial prison time for using or carrying a gun during a federal crime of violence.

What it's about

The Court agreed with part of the Fifth Circuit’s ruling, wiped out another part (vacated), and sent the case back for further proceedings (remanded).

Davis was part of a broader Supreme Court review of “residual clauses,” catchall wording used to identify violent offenses.

Question presented

Whether the subsection-specific definition of "crime of violence" in 18 U.S.C. 924(c)(3)(B), which applies only in the limited context of a federal criminal prosecution for possessing, using, or carrying a firearm in connection with acts comprising such a crime, is unconstitutionally vague.

What the Court decided

Holding

Section 924(c)(3)(B) is unconstitutionally vague. 903 F. 3d 483, affirmed in part, vacated in part, and remanded.
