III. PRIOR ADMINISTRATIVE PROCEEDINGS
Plaintiff filed for a period of disability and disability insurance benefits ("DIB") on February 13, 2007, alleging disability since December 15, 2006. [AR 44, 85.] After Plaintiff's application was initially denied on September 19, 2007, she requested an administrative hearing, which was held before an Administrative Law Judge ("ALJ") on May 11, 2009.*fn1 [AR 27-43, 47-52, 55.] Plaintiff appeared with counsel, and testimony was taken from Plaintiff and vocational expert Gregory Jones. [AR 27-43.] The ALJ issued a decision denying benefits on August 21, 2009. [AR 11-22.] On September 18, 2009, Plaintiff sought review with the Appeals Council and submitted additional evidence. [AR 5-7.] When the Appeals Council denied review on July 30, 2010, the ALJ's decision became the Commissioner's final decision. [AR 1-4.]
Under 42 U.S.C. § 405(g), a district court may review the Commissioner's decision to deny benefits. The Commissioner's (or ALJ's) findings and decision should be upheld if they are free of legal error and supported by substantial evidence. However, if the court determines that a finding is based on legal error or is not supported by substantial evidence in the record, the court may reject the finding and set aside the decision to deny benefits. See Aukland v. Massanari, 257 F.3d 1033, 1035 (9th Cir. 2001); Tonapetyan v. Halter, 242 F.3d 1144, 1147 (9th Cir. 2001); Osenbrock v. Apfel, 240 F.3d 1157, 1162 (9th Cir. 2001); Tackett v. Apfel, 180 F.3d 1094,1097 (9th Cir. 1999); Reddick v. Chater, 157 F.3d 715, 720 (9th Cir. 1998); Smolen v. Chater, 80 F.3d 1273, 1279 (9th Cir. 1996); Moncada v. Chater, 60 F.3d 521, 523 (9th Cir. 1995)(per curiam).
"Substantial evidence is more than a scintilla, but less than a preponderance." Reddick, 157 F.3d at 720. It is "relevant evidence which a reasonable person might accept as adequate to support a conclusion." Id. To determine whether substantial evidence supports a finding, a court must review the administrative record as a whole,"weighing both the evidence that supports and the evidence that detracts from the Commissioner's conclusion." Id. "If the evidence can reasonably support either affirming or reversing," the reviewing court "may not substitute its judgment" for that of the Commissioner. Reddick, 157 F.3d at 720-721; see also Osenbrock, 240 F.3d at 1162.
