NOT FOR PUBLICATION UNITED STATES COURT OF APPEALS FILED FOR THE NINTH CIRCUIT DEC 15 2009 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS STACEY M. BROWN, No. 08-17357 Plaintiff - Appellant, D.C. No. 2:07-cv-00638-CMK v. MEMORANDUM * MICHAEL J. ASTRUE, Commissioner of Social Security, Defendant - Appellee. Appeal from the United States District Court for the Eastern District of California Craig Kellison, Magistrate Judge, Presiding Submitted December 11, 2009** San Francisco, California Before: O’SCANNLAIN, RAWLINSON and BEA, Circuit Judges. Appellant Stacey Brown appeals the district court’s entry of summary judgment in favor of the Commissioner. * This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3. ** The panel unanimously finds this case suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). Substantial evidence supports the ALJ’s adverse credibility finding because he properly relied upon medical records of Brown’s examining physician, Dr. Chee, that contradicted Brown’s testimony regarding the severity of her symptoms. See Carmickle v. Comm’r, Soc. Sec. Admin., 533 F.3d 1155, 1161 (9th Cir. 2008) (concluding that the ALJ’s adverse credibility determination was proper when it relied on the examining physician’s contradictory opinion). Because this is a valid basis supporting the ALJ’s decision, any error the ALJ made in improperly considering other evidence was harmless. See Bray v. Comm’r of Soc. Sec. Admin., 554 F.3d 1219, 1227 (9th Cir. 2009). The ALJ’s assessment of Brown’s RFC was proper because once an adverse credibility determination is made, an ALJ is not required to credit that testimony in assessing a claimant’s RFC. See Bayliss v. Barnhart, 427 F.3d 1211, 1215, 1217 (9th Cir. 2005). AFFIRMED. 2
