- What it's about
The Court denied Lopez’s petition for review, leaving the Fifth Circuit’s ruling and sentence in place. Lopez had argued that her prior state drug conviction could not count as a “controlled substance offense” under the federal Sentencing Guidelines because the state law covered conduct involving substances beyond the federal definition.
Question presented
Whether a prior conviction for a state drug offense is a “controlled substance offense” under the United States Sentencing Guidelines, when the state statute is broader than the federal definition of a controlled substance?
