Summary

The United States Court of Appeals for the Fourth Circuit affirmed Gregory Palmer’s conviction for knowingly concealing criminal history to procure United States citizenship under 18 U.S.C. § 1425(a). The court rejected Palmer’s claims concerning unconstitutional preindictment delay and the exclusion of his state guilty plea based on alleged ineffective assistance of counsel. Although the court held that the district court improperly excluded certain expert testimony under Federal Rule of Evidence 704(b), it found the error harmless.

Questions Presented

  1. Whether the indictment should have been dismissed for unconstitutional preindictment delay when Palmer claimed that his deceased mother could have supplied exculpatory testimony.
  2. Whether the district court should have suppressed Palmer's state guilty plea because his counsel allegedly failed to advise him of possible immigration consequences.
  3. Whether Federal Rule of Evidence 704(b) barred expert testimony about Palmer's reading level and the readability of the naturalization application question.
  4. Whether any error in excluding the expert testimony was sufficiently prejudicial to require reversal.

Holdings

  1. A defendant challenging an indictment brought within the statute of limitations must first demonstrate substantial actual prejudice from the delay; Palmer failed to meet that burden because his assertions about his deceased mother's testimony were speculative and the proposed evidence was cumulative.
  2. A defendant may not obtain suppression of a state guilty plea in a federal prosecution by collaterally challenging the plea based on alleged ineffective assistance concerning immigration consequences; the recognized exception for a complete denial of counsel does not extend to Padilla-type ineffective-assistance claims.
  3. Rule 704(b) narrowly bars an expert's conclusion that the defendant did or did not have the mental state or condition constituting an element of the offense; it does not bar expert opinions about facts related to mental state when those opinions leave the ultimate inference to the jury.
  4. The erroneous exclusion of the expert's grade-level opinions was harmless because the jury heard extensive, substantially equivalent evidence concerning Palmer's language-processing limitations and the excluded testimony was unlikely to have affected the verdict.

Key quotations

A defendant must first show he suffered “substantial actual prejudice” because of the delay. (slip op. at 6)
If the expert’s opinion leaves room for the jury to draw its own conclusion about the defendant’s mental state, Rule 704(b) doesn’t block it. (slip op. at 10-11)

Factual background

Palmer applied for naturalization in 2011 and twice answered no to a question asking whether he had ever committed a crime or offense for which he had not been arrested. He became a United States citizen after passing language-based citizenship tests and completing an interview. In 2013, he pleaded guilty in North Carolina to attempted statutory rape based on conduct in 2008, and the state court sentenced him to 157 to 198 months' imprisonment. A federal jury later found that Palmer knowingly concealed his criminal history to procure citizenship.

Procedural history

A federal grand jury indicted Palmer in 2021 under 18 U.S.C. § 1425(a). The United States District Court for the Western District of North Carolina denied his motion to dismiss for preindictment delay and his motion to suppress his state guilty plea. At trial, the district court excluded portions of expert testimony concerning Palmer's reading level and the readability of the naturalization question; the jury convicted him, and the district court sentenced him to six months' imprisonment concurrent with his state sentence. The Fourth Circuit held that exclusion of the grade-level testimony was error but harmless and affirmed.
