July 6, 2026 ·24-1524 ·Panel Decision ·Barron, Chief Judge · By Aisha Johnson

The First Circuit affirmed the defendant's federal convictions but found error in applying a career offender sentencing enhancement. The court held that the enhancement was inapplicable because the prior state conviction did not involve a substance controlled under federal law at the time of federal sentencing.

Background

Rey David Fulcar pleaded guilty to three federal counts: possession of a firearm by a prohibited person, and two counts of possession with intent to distribute controlled substances. He challenged the validity of his pleas, the constitutionality of the firearm statute, and the application of three sentencing enhancements under the United States Sentencing Guidelines. The District Court had denied his motion to suppress evidence, denied his motion to dismiss the firearm count, and applied enhancements including the career offender guideline based on a 2008 Massachusetts conviction for possession with intent to distribute cocaine.

The court’s reasoning

The court reviewed the Rule one claim for plain error and found no error, as due process does not require advising a defendant of the right to appeal a suppression motion when entering an unconditional plea. The Second Amendment challenge was waived because the defendant failed to develop arguments beyond incorporating prior briefing. Regarding sentencing, the court analyzed the career offender guideline’s definition of a controlled substance. It concluded that the term refers to the law in effect at the time of federal sentencing, not the time of the prior conviction. Since the substance involved in the prior conviction was removed from the federal Controlled Substances Act schedule by the time of sentencing, the enhancement did not apply. However, the court affirmed the sentence because the District Court explicitly stated it would have imposed the same sentence regardless of the Guidelines calculation.

What it means going forward

The ruling clarifies that the definition of a controlled substance for career offender enhancements is determined by federal law as it exists at the time of federal sentencing, not at the time of the prior state conviction. This may affect sentencing calculations for defendants with prior state convictions involving substances later removed from federal schedules.
