Patel v. Mukasey, 526 F.3d 800, ___ (5th Cir. Apr. 29, 2008) (the elements of the federal offense of misprision of a felony, in violation of 18 U.S.C. 4, were described as "(1) knowledge that a felony was committed; (2) failure to notify the authorities of the felony; and (3) an affirmative step to conceal the felony. See United States v. Adams, 961 F.2d 505, 508 (5th Cir.1992). "[U]nder the misprision statute, the defendant must commit an affirmative act to prevent discovery of the earlier felony." Id. "Mere failure to make known does not suffice." Id. at 508-09 (citation omitted).

Atunnise v. Mukasey, 523 F.3d 830 (7th Cir. Apr. 30, 2008) (case remanded to allow immigration judge to reconsider petitioner's eligibility for a waiver of inadmissibility under INA 212(d)(3) where flaw in form DS-156 did not allow petitioner to correctly answer a question regarding her immigration status or the consular office to realize that she needed to apply for a waiver, and IJ failed to alert her to all the avenues of relief or afford her an opportunity to apply).

Patel v. Mukasey, 526 F.3d 800, ___ (5th Cir. Apr. 29, 2008) ("Moreover, unlike the federal aiding and abetting statute involved in James, the federal misprision of a felony statute defines a separate offense, distinct from the underlying felony. See James, 464 F.3d at 510 n. 24 (citing Londono-Gomez v. INS, 699 F.2d 475, 476 (9th Cir.1983)). Thus, the fact that Patel was specifically indicted for misprision of a bank fraud is irrelevant to our inquiry of whether the statutory definition of the offense itself necessarily entails fraud or deceit.").
