MEMORANDUM OPINION AND ORDER
Plaintiff filed this action on July 25, 2011, seeking review of the Commissioner's denial of her applications for disabled widow's Insurance Benefits and Disability Insurance Benefits. The parties filed Consents to proceed before the undersigned Magistrate Judge on August 10, 2011, and August 16, 2011. Pursuant to the Court's Order, the parties filed a Joint Stipulation on March 26, 2012, that addresses their positions concerning the disputed issue in the case. The Court has taken the Joint Stipulation under submission without oral argument.
Plaintiff was born on January 6, 1956. [Administrative Record ("AR") at 67.] She completed two years of college, and has past relevant work experience as an assistant store manager, a deli manager, and an in-home care provider. [AR at 156, 159, 179, 185-87.]
Plaintiff filed an application for disabled widow's Insurance Benefits on January 11, 2008, and an application for Disability Insurance Benefits on July 27, 2009, alleging that she has been unable to work since February 28, 2006, due to problems with her shoulder, back, and elbow, mental problems, and anxiety.*fn1 [AR at 17, 68-72, 112-15, 138-45, 154-60, 164-70.] After her applications were denied initially, plaintiff requested a hearing before an Administrative Law Judge ("ALJ"). [AR at 37-38, 68-74.] A hearing was held on October 13, 2009, at which time plaintiff appeared with counsel and testified on her own behalf. [AR at 39-66.] A vocational expert ("VE") also testified. [AR at 59-65.] On November 16, 2009, the ALJ determined that plaintiff was not disabled. [AR at 17-25.] On March 10, 2011, the Appeals Council denied plaintiff's request for review. [AR at 3-7, 13.] This action followed.*fn2
Pursuant to 42 U.S.C. § 405(g), this Court has authority to review the Commissioner's decision to deny benefits. The decision will be disturbed only if it is not supported by substantial evidence or if it is based upon the application of improper legal standards. Moncada v. Chater, 60 F.3d 521, 523 (9th Cir. 1995); Drouin v. Sullivan, 966 F.2d 1255, 1257 (9th Cir. 1992).
In this context, the term "substantial evidence" means "more than a mere scintilla but less than a preponderance -- it is such relevant evidence that a reasonable mind might accept as adequate to support the conclusion." Moncada, 60 F.3d at 523; see also Drouin, 966 F.2d at 1257. When determining whether substantial evidence exists to support the Commissioner's decision, the Court examines the administrative record as a whole, considering adverse as well as supporting evidence. Drouin, 966 F.2d at 1257; Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989). Where the evidence is susceptible to more than one rational interpretation, the Court must defer to the decision of the Commissioner. Moncada, 60 F.3d at 523; Andrews v. Shalala, 53 F.3d 1035, 1039-40 (9th Cir. 1995); Drouin, 966 F.2d at 1258.
IV. THE EVALUATION OF DISABILITY
Persons are "disabled" for purposes of receiving Social Security benefits if they are unable to engage in any substantial gainful activity owing to a physical or mental impairment that is expected to result in death or which has lasted or is expected to last for a continuous period of at least twelve months. 42 U.S.C. § 423(d)(1)(A); Drouin, 966 F.2d at 1257.
A. THE FIVE-STEP EVALUATION PROCESS
The Commissioner (or ALJ) follows a five-step sequential evaluation process in assessing whether a claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920; Lester v. Chater, 81 F.3d 821, 828 n.5 (9th Cir. 1995, as amended April 9, 1996). In the first step, the Commissioner must determine whether the claimant is currently engaged in substantial gainful activity; if so, the claimant is not disabled and the claim is denied. Id. If the claimant is not currently engaged in substantial gainful activity, the second step requires the Commissioner to determine whether the claimant has a "severe" impairment or combination of impairments significantly limiting her ability to do basic work activities; if not, a finding of non-disability is made and the claim is denied. Id. If the claimant has a "severe" impairment or combination of impairments, the third step requires the Commissioner to determine whether the impairment or combination of impairments meets or equals an impairment in the Listing of Impairments ("Listing") set forth at 20 C.F.R., Part 404, Subpart P, Appendix 1; if so, disability is conclusively presumed and benefits are awarded. Id. If the claimant's impairment or combination of impairments does not meet or equal an impairment in the Listing, the fourth step requires the Commissioner to determine whether the claimant has sufficient "residual functional capacity" to perform her past work; if so, the claimant is not disabled and the claim is denied. Id. The claimant has the burden of proving that she is unable to perform past relevant work. Drouin, 966 F.2d at 1257. If the claimant meets this burden, a ...
