The Third Circuit Court of Appeals has denied a request from David Lettieri for a writ of mandamus. This decision affects Lettieri, who is currently serving a twenty-year prison sentence. The court ruled that his petition did not meet the necessary criteria for such a drastic remedy.

Lettieri's case revolves around his conviction for attempting to persuade a minor to engage in unlawful sexual activity. He was found guilty in 2023 and is currently incarcerated at the Federal Medical Center in Devens, Massachusetts. His request for mandamus relief sought to compel the District Court to sever and grant two separate petitions he had filed.

Background

David Lettieri was convicted in 2023 in the United States District Court for the Western District of New York. He was sentenced to twenty years in prison for violating 18 U.S.C. § 2422(b). Shortly before his sentencing, he filed a separate complaint against TD Bank in the United States District Court for the District of New Jersey. After more than two years of litigation, a legal representative of Lettieri agreed to dismiss the case, but Lettieri later appealed the dismissal.

His appeal was dismissed due to failure to pay the required filing fee. While his TD Bank lawsuit was ongoing, Lettieri filed a petition for relief in June 2025, alleging that someone at FMC Devens had interfered with legal mail related to his civil matter. He claimed this interference denied him access to the courts. He sought a reduction in his prison sentence and supervised release term as a remedy.

The Ruling

The Third Circuit Court ruled against Lettieri's request for a writ of mandamus, stating that he had not met the necessary burden for such a remedy. The court noted, "A writ of mandamus is a 'drastic remedy' that may be granted only in 'extraordinary circumstances in response to an act amounting to a judicial usurpation of power.'" The judges on the panel included Chief Judge Chagares, Judge Hardiman, and Judge Restrepo.

Furthermore, the court found that Lettieri's petition was moot regarding his request for severance. This was due to the District Court's prior dismissal of his underlying request for relief as frivolous. The court emphasized that if Lettieri believed the District Court had erred, he should pursue an appeal rather than seek mandamus relief.

Impact

This ruling has significant implications for Lettieri and others in similar situations. The denial of the writ of mandamus means that Lettieri cannot compel the District Court to take action on his claims regarding the severance of his petitions. The court's decision clarifies that mandamus is not a substitute for an appeal and that petitioners must demonstrate a clear right to the relief sought.

The ruling reinforces the principle that courts will not intervene in lower court decisions unless there are extraordinary circumstances. This case may serve as a precedent for future cases where incarcerated individuals seek similar relief, emphasizing the importance of following proper legal channels for appeals.

What's Next

Lettieri has the option to appeal the dismissal of his underlying request. He has until October 13, 2026, to file an appeal with the Third Circuit Court. Details regarding any potential related cases were not available in the court filing.
