Whether the MBTA felony provision, 16 U.S.C. § 707(b)(2), requires the government to prove that a defendant acted knowingly or with some other form of scienter.
Holding
No. The court held that Congress did not make scienter an element of the MBTA offense, including its felony sale provision.
Reasoning
Sixth Circuit precedent had already held that violations of the MBTA and its regulations are strict-liability offenses. Other federal courts had reached the same conclusion. Those earlier cases involved misdemeanor prosecutions, however, so the court did not disturb them.
Although courts sometimes infer a mens rea requirement into a statute that is silent on intent, that interpretive move is available when Congress borrows a crime from the common law. Selling protected migratory-bird parts is not a common-law offense, so the court concluded it could not save § 707(b)(2) by reading scienter into it.
The government's legislative-history argument did not resolve the constitutional problem. Even if Congress deliberately retained strict liability when it added the felony provision in 1960, the decisive question was whether a felony conviction without proof of culpable intent comports with due process.
