United States v. Santonastaso, No. 22-1944 (1st Cir. 2024)
Annotate this Case
The defendant, Antonio Santonastaso, was convicted of making a false statement to federal investigators and attempted witness tampering. The charges stemmed from a 2018 investigation by the Federal Aviation Administration (FAA) into allegations that Santonastaso was flying a helicopter without the necessary certifications. During the investigation, Santonastaso falsely claimed that he had the requisite certifications to fly and that his previous involvement in a 2000 helicopter theft was part of an undercover operation.
The case was first heard in the United States District Court for the District of Massachusetts, where Santonastaso was found guilty. He appealed the decision, arguing that the government's evidence was insufficient to prove his guilt and that the district court erred by not giving a materiality instruction based on the Supreme Court's decision in Maslenjak v. United States.
The United States Court of Appeals for the First Circuit affirmed the lower court's decision. The court found that the evidence was sufficient for the jury to find Santonastaso guilty of making a false statement to federal investigators and attempted witness tampering. The court also ruled that the district court did not commit instructional error in rejecting Santonastaso's proposed materiality instruction. The court held that the law-of-the-circuit doctrine foreclosed the application of the Maslenjak materiality standard to § 1001(a) prosecutions, and that the district court's instruction correctly stated the controlling law on materiality.
