In one sentence

In Kasib Shamsideen v. United States, Judge Karas dismissed Shamsideen’s Rehaif challenge with prejudice as untimely, procedurally defaulted, and meritless.

Who this affects

Kasib Shamsideen’s challenge to his federal firearm-possession conviction was dismissed with prejudice; the United States prevailed.

What happened

Kasib Shamsideen v. United States concerned Shamsideen’s petition asking the court to overturn his conviction for possessing a firearm after a felony conviction. He relied on the Supreme Court’s decision in Rehaif v. United States, which requires the government to prove that a defendant knew both that he possessed a firearm and that he belonged to a prohibited category.

The government opposed the petition. The court ruled that Shamsideen filed too late, had not raised the argument earlier in the required way, and could not show that the alleged error harmed him. The court also found that his prior felony convictions and prison sentences showed he knew he was barred from possessing a firearm.

Judge Karas dismissed the petition with prejudice. The court also declined to issue a certificate allowing an appeal and certified that an appeal would not be taken in good faith.

Background

Kasib Shamsideen, proceeding without a lawyer, filed a petition under 28 U.S.C. § 2255 seeking to vacate, set aside, or correct his conviction for unlawfully possessing a firearm after a felony conviction, in violation of 18 U.S.C. § 922(g)(1). A jury convicted him in 2004, and the court sentenced him in 2005 to 39 months’ imprisonment and three years of supervised release.

The petition relied on the Supreme Court’s 2019 decision in Rehaif v. United States. That decision held that, for a conviction under § 922(g)(1), the government must prove that the defendant knew he possessed a firearm and knew he belonged to the category of people prohibited from possessing one.

Court’s Analysis

The court identified three independent reasons for rejecting the petition.

First, the petition was untimely. Section 2255 generally gives a defendant one year to file a petition, subject to specified exceptions. The court held that Rehaif did not recognize a new constitutional right made retroactive to cases challenging final convictions. The court further held that the petition would still have been filed too late even if Rehaif qualified for that exception, because Shamsideen waited more than two years after the decision to file and identified no government action or newly discovered fact that prevented an earlier filing.

Second, the claim was procedurally defaulted. Procedural default generally prevents a defendant from raising a claim in a post-conviction petition when the defendant did not raise it on direct appeal. The court found that Shamsideen had not shown cause for failing to raise the argument earlier, actual prejudice from the alleged error, or factual innocence. The court rejected the argument that the claim’s likely futility before Rehaif excused the omission. It also found no actual prejudice because Shamsideen had previously received prison sentences exceeding one year for felony convictions, including a 1995 weapons conviction and a 1999 arson conviction. The court concluded that these convictions showed he knew he was a prohibited person under § 922(g)(1).

Third, the court reached the merits and found no basis for relief. Even assuming the government had not adequately proved Shamsideen’s knowledge of his prohibited status at trial, the court held that reliable evidence established that he knew about at least one felony conviction punishable by more than one year in prison. The court noted that the government had identified his prior felony convictions when charging him.

Disposition

The court dismissed the petition with prejudice. It declined to issue a certificate of appealability because Shamsideen had not made a substantial showing that a constitutional right was denied. The court also certified under 28 U.S.C. § 1915(a)(3) that an appeal from the judgment on the merits would not be taken in good faith. The clerk was directed to enter judgment for the United States, close the civil case, and mail the order to Shamsideen.
