*11 SUMMARY ORDER
Petitioner Nicercio Jose Procopio, a citizen of Brazil, petitions for review of the April 8, 2007 BIA order affirming the September 2, 2005 decision of Immigration Judge (“IJ”) Michael W. Straus, denying his application for cancellation of removal under section 240A(b) of the Immigration and Nationality Act (“INA”), 8 U.S.C. § 1229b(b), and ordering him removed to Brazil. In re Procopio, A98 038 901 (B.I.A. Apr. 3, 2007), affg No. A98 038 901 (Immig.Ct.Hartford, Conn. Sept. 2, 2005). We assume the parties’ familiarity with the underlying facts and procedural history of the case.
Procopio argues that the BIA erred in denying his application for cancellation of removal because it applied the wrong standard for “exceptional and extremely unusual hardship” under 8 U.S.C. § 1229b(b)(l)(D). Although we lack jurisdiction to review “exceptional and extremely unusual hardship” determinations by the BIA because they are discretionary judgments, see Barco-Sandoval v. Gonzales, 516 F.3d 35, 39 (2d Cir.2008), we retain jurisdiction under the REAL ID Act to review “constitutional claims or questions of law,” 8 U.S.C. § 1252(a)(2)(D). “[T]he argument that a discretionary decision was ‘based on a legally erroneous standard’ raises a ‘question of law”.... ” Barco-Sandoval, 516 F.3d 35, 40. However, as we held in Barco-Sandoval, Procopio’s legal argument that the IJ erroneously applied the standard from Matter of Monreal-Aguinaga, 23 I. & N. Dec. 56 (B.I.A.2001), and not the standard from Matter of Reciñas, 23 I. & N. Dec. 467 (B.I.A.2002), “is so insubstantial and frivolous as to be inadequate to invoke federal-question jurisdiction.” Barco-Sandoval, 516 F.3d 35, 40 (“Reciñas is so obviously an application of Monreal-Aguinaga, leaving the latter’s standard intact, that [the petitioner’s] argument that the agency incorrectly relied on Monreal-Aguinaga rather than Reciñas in denying his application for cancellation of removal does not even reach the level of being colorable.”).
We likewise lack jurisdiction to review Procopio’s next argument that, in making its discretionary determination, the agency failed to properly consider all of his evidence, including testimony from his expert witness, such that he was denied due process of law. In certain circumstances, an IJ’s fact-finding may be flawed by an error of law, “such as might arise where the IJ states that his decision was based on petitioner’s failure to testify to some pertinent fact when the record of the hearing reveals unambiguously that the petitioner did testify to that fact.” Xiao Ji Chen v. U.S. Dep’t of Justice, 471 F.3d 315, 329 (2d Cir.2006). However, “regardless of the rhetoric employed in the petition,” where, as here, the petitioner “merely quarrels over the correctness of the factual findings or justification for the discretionary choices,” we lack jurisdiction to review the agency’s determination. Id.
Finally, we lack jurisdiction to review Procopio’s contention that a three-member panel of the BIA, rather than a single member, should have decided his case before the agency. See Kambolli v. Gonzales, 449 F.3d 454, 465 (2d Cir.2006) (“[W]e lack jurisdiction to review a claim that a single BIA member erred in deciding to resolve unilaterally an appeal of an IJ’s order and not to refer the case to a three-member BIA panel.”).
For the foregoing reasons, the petition for review is DISMISSED. The motion for stay of deportation is DENIED as moot.
