Matter of O'Sullivan, 10 I. & N. Dec. 320 (BIA 1963) (BIA can look behind facially valid conviction where state court wholly lacked authority to issue order).

Penuliar v. Mukasey, 523 F.3d 963 (9th Cir. Apr. 22, 2008) ("Finally, insofar as the IJ relied on the probation report to establish that Penuliar pled guilty to a "crime of violence," he was in error. See, e.g., United States v. Vidal, 504 F.3d 1072, 1087 n.25 (9th Cir. 2007) (en banc) (citing United States v. Franklin, 235 F.3d 1165, 1171 (9th Cir. 2000)) (explaining that a presentence report, even when considered in conjunction with charging papers, is insufficient to establish what facts a defendant admitted in his plea).").

Acosta v. U.S. Att'y Gen., 524 F.3d 1191 (11th Cir. Apr. 16, 2008) (court lacked subject matter jurisdiction to hear petition for review of order denying continuance of removal proceedings, which presented only a "garden variety" abuse of discretion claim, rather than a constitutional claim or question of law sufficient to confer jurisdiction under 8 U.S.C. 1252(a)(2)(C) and (D)).

Acosta v. U.S. Att'y Gen., 524 F.3d 1191 (11th Cir. Apr. 16, 2008) (court of appeal lacked subject matter jurisdiction to hear petition for review because petitioner's conviction was a crime "related to a controlled substance" under 8 U.S.C. 1182(a)(2)(A)(i)(II); and (2)).

Burgess v. United States, ___ U.S. ___, ___,(Apr. 16, 2008) ("Notably, [21 U.S.C.] 802(44) includes foreign offenses punishable by more than one year, while 802(13) includes only federal and state offenses. Incorporation of 802(13) into 841(b)(1)(A) would exclude enhancement based on a foreign offense, notwithstanding the express inclusion of foreign offenses in 802(44)'s definition of "felony drug offense." Furthermore, some States and many foreign jurisdictions do not label offenses as felonies or misdemeanors.").

Piedrahita v. Mukasey, 524 F.3d 142 (1st Cir. Apr. 28, 2008) (petition for review denied where petitioner failed to raise relevant issues in his opening brief, and addressed a dispositive issue in an incoherent and perfunctory manner).

Ortiz-Magana v. Mukasey, 523 F.3d 1042 (9th Cir. Apr. 28, 2008) (noncitizen failed to establish a reasonable probability that the state would apply the statute of conviction outside the definition of the ground of deportation in the aiding and abetting an assault with a deadly weapon, aggravated felony crime of violence context, since he presented no evidence that California has applied aiding and abetting assault outside the generic definition of a crime of violence).

United States v. Aguila-Montes de Oca, 523 F.3d 1071 (9th Cir. Apr.

United States v. Aguila-Montes de Oca, 523 F.3d 1071 (9th Cir. Apr. 28, 2008) ("In another recent en banc decision of our court, the defendant Vidal did not plead guilty "as charged." United States v. Vidal, 504 F.3d 1072, 1087 (9th Cir. 2007). As a result, our en banc court had "no way of knowing what conduct Vidal admitted when he pled guilty to conduct that was not identical to that charged in Count One of the Complaint." Id. at 1088.

Martinez v. INS, 523 F.3d 365 (2d Cir. Apr. 23, 2008) (application of the stop-time rule under INA 240A(d)(1)(B), 8 U.S.C. 1229b(d)(1)(B), as applied to a conviction occurring before IIRAIRA effective date was not impermissibly retroactive).
