The opinion of the court was delivered by: Paul L. Abrams United States Magistrate Judge
MEMORANDUM OPINION AND ORDER
Plaintiff filed this action on September 3, 2010, seeking review of the Commissioner's denial of her application for Supplemental Security Income payments. The parties filed Consents to proceed before the undersigned Magistrate Judge on October 27, 2010, and November 23, 2010. Pursuant to the Court's Order, the parties filed a Joint Stipulation on June 6, 2011, that addresses their positions concerning the disputed issues in the case. The Court has taken the Joint Stipulation under submission without oral argument.
Plaintiff was born on April 14, 1960. [Administrative Record ("AR") at 26, 56, 138.] She has an eleventh grade education, some vocational training, and has past relevant work experience as, among other things, a home care provider, noon aide, recovery associate, waitress, and sales associate. [AR at 22, 26, 33-35, 112-13, 116, 118-23, 199.]
On March 31, 2007, plaintiff protectively filed her application for Supplemental Security Income payments, alleging that she has been disabled since March 23, 2007, due to hepatitis C, an enlarged liver, depression, fibromyalgia, and other impairments. [AR at 56, 90-98, 111-12, 125, 131, 141.] After her application was denied initially and upon reconsideration, plaintiff requested a hearing before an Administrative Law Judge ("ALJ"). [AR at 60-63, 65-72.] A hearing was held on September 9, 2009, at which time plaintiff appeared with her representative*fn1 and testified on her own behalf. [AR at 23-55.] A vocational expert also testified. [AR at 52-55.] On November 2, 2009, the ALJ determined that plaintiff was not disabled. [AR at 13-22.] The Appeals Council denied plaintiff's request for review on July 6, 2010. [AR at 1-3, 10.] This action followed.
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 ...
