MEMORANDUM ***

Petitioners Samvel Mkhoyan and Liana Grigoryan seek review of a final order of removal issued by the Board of Immigration Appeals (BIA). The BIA affirmed the Immigration Judge’s (IJ) adverse credibility determination and denial of their application for asylum, withholding of removal, and relief under the Convention Against Torture (CAT). 1

1. Substantial evidence supports the IJ’s adverse credibility determination given Mkhoyan’s implausible explanations for the factual inconsistencies in his testimony and his failure to provide corroborating evidence. See Shrestha v. Holder, 590 F.3d 1034, 1047-48 (9th Cir. 2010).

2. Substantial evidence supports denial of Mkhoyan’s asylum application, because he failed to establish that his mistreatment constituted persecution and was on account of his political opinion. Although Mkhoyan was detained overnight and beaten by the police, we have held that single, isolated encounters with the authorities do not constitute past persecution. See Prasad v. INS, 47 F.3d 336, 339 (9th Cir. 1995); Gu v. Gonzales, 454 F.3d 1014, 1018, 1020-21 (9th Cir. 2006). Further, the evidence does not compel a finding that his political opinion was a central reason for his mistreatment, given that he was detained for refusing to vacate the military base. See Zhiqiang Hu, 652 F.3d at 1017.

3. Because Mkhoyan failed to establish eligibility for asylum, his application for withholding of removal also fails. See Barrios v. Holder, 581 F.3d 849, 854 (9th Cir. 2009), as amended (“[A]n alien who *638 fails to satisfy the lower standard of proof required to establish eligibility for asylum necessarily fails to establish eligibility for withholding of removal.”) (citation omitted).

4. Because Mkhoyan’s application for CAT relief was premised on the same evidence as his asylum and withholding of removal claims, CAT relief was properly denied. See Cortez-Pineda v. Holder, 610 F.3d 1118, 1125 (9th Cir. 2010).

PETITION DENIED.
