MEMORANDUM OPINION AND ORDER REVERSING DECISION OF THE COMMISSIONER OF SOCIAL SECURITY AND REMANDING FOR FURTHER PROCEEDINGS PROCEEDINGS
On June 27, 2012, Sheera Jean-Marie ("Plaintiff" or "Claimant") filed a complaint seeking review of the decision by the Commissioner of Social Security ("Commissioner") denying Plaintiff's applications for Social Security Disability Insurance benefits and Supplemental Security Income Disability benefits. The Commissioner filed an Answer on October 15, 2012. On December 28, 2012, the parties filed a Joint Stipulation ("JS"). The matter is now ready for decision.
Pursuant to 28 U.S.C. § 636(c), both parties consented to proceed before this Magistrate Judge. After reviewing the pleadings, transcripts, and administrative record ("AR"), the Court concludes that the Commissioner's decision must be reversed and remanded for further proceedings in accordance with this Memorandum Opinion and Order and with law.
Plaintiff is a 35 year old female who applied for Social Security Disability Insurance benefits on July 19, 2007, and for Supplemental Security Disability Income benefits on July 24, 2007, alleging disability beginning March 1, 2001. (AR 18.) Plaintiff did not engage in substantial gainful activity from the March 1, 2001, alleged onset date of disability through December 30, 2009. (AR 21.)
Plaintiff's claims were denied initially on November 9, 2007, and affirmed in an unfavorable decision dated February 26, 2009. (AR 18.)
On June 12, 2009, the Appeals Council vacated the February 26, 2009, unfavorable decision and remanded the case to obtain a State Agency mental consultative examination ("CE"), as well as for further evaluation of Plaintiff's substantial gainful activity and the severity of her impairments. (AR 18.)
Accordingly, a hearing was held before Administrative Law Judge ("ALJ") David G. Marcus on May 25, 2010, in Downey, California. (AR 18.) Claimant appeared and testified at the hearing. (AR 18.) Plaintiff was represented by counsel. (AR 18.) Vocational expert ("VE") Randi Langford-Hetrick also appeared and testified at the hearing. (AR 18.) The ALJ issued a partially favorable decision on August 4, 2010. (AR 18-28.)
As reflected in the Joint Stipulation, Plaintiff raises the following disputed issues as the grounds for reversal and remand:
1. Whether the ALJ disability determination for the period July 20, 2007, through November 30, 2009, is supported by substantial evidence.
2. Whether the ALJ's credibility determination is supported by substantial evidence.
Under 42 U.S.C. § 405(g), this Court reviews the ALJ's decision to determine whether the ALJ's findings are supported by substantial evidence and free of legal error. Smolen v. Chater, 80 F.3d 1273, 1279 (9th Cir. 1996); see also DeLorme v. Sullivan, 924 F.2d 841, 846 (9th Cir. 1991) (ALJ's disability determination must be supported by substantial evidence and based on the proper legal standards).
Substantial evidence means "'more than a mere scintilla,' but less than a preponderance." Saelee v. Chater, 94 F.3d 520, 521-22 (9th Cir. 1996) (quoting Richardson v. Perales, 402 U.S. 389, 401 (1971)). Substantial evidence is "such relevant evidence as a reasonable mind might accept as adequate to support a conclusion." Richardson, 402 U.S. at 401 (internal quotation marks and citation omitted).
This Court must review the record as a whole and consider adverse as well as supporting evidence. Robbins v. Soc. Sec. Admin., 466 F.3d 880, 882 (9th Cir. 2006). Where evidence is susceptible to more than one rational interpretation, the ALJ's decision must be upheld. Morgan v. Comm'r of the Soc. Sec. Admin., 169 F.3d 595, 599 (9th Cir. 1999). "However, a reviewing court must consider the entire record as a whole and may not affirm simply by isolating a 'specific quantum of supporting evidence.'" Robbins, 466 F.3d at 882 (quoting Hammock v. Bowen, 879 F.2d 498, 501 (9th Cir. 1989)); see also Orn v. Astrue, 495 F.3d 625, 630 (9th Cir. 2007).
THE SEQUENTIAL EVALUATION
The Social Security Act defines disability as the "inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or . . . can be expected to last for a continuous period of not less than 12 months." 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A). The Commissioner has established a five-step sequential process to determine whether a claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920.
The first step is to determine whether the claimant is presently engaging in substantial gainful activity. Parra v. Astrue, 481 F.3d 742, 746 (9th Cir. 2007). If the claimant is engaging in substantial gainful activity, disability benefits will be denied. Bowen v. Yuckert, 482 U.S. 137, 140 (1987). Second, the ALJ must determine whether the claimant has a severe impairment or combination of impairments. Parra, 481 F.3d at 746. An impairment is not severe if it does not significantly limit the claimant's ability to work. Smolen v. Chater, 80 F.3d 1273, 1290 (9th Cir. 1996). Third, the ALJ must determine whether the impairment is listed, or equivalent to an impairment listed, in 20 C.F.R. Pt. 404, Subpt. P, Appendix I of the regulations. Parra, 481 F.3d at 746. If the impediment meets or equals one of the listed impairments, the claimant is presumptively disabled. Bowen v. Yuckert, 482 U.S. at 141. Fourth, the ALJ must determine whether the impairment prevents the claimant from doing past relevant work. Pinto v. Massanari, 249 F.3d 840, 844-45 (9th Cir. 2001). Before making the step four determination, the ALJ first must determine the claimant's residual functional capacity ("RFC").*fn1 20 C.F.R. § 416.920(e). The RFC must consider all of the claimant's impairments, including those that are not severe. 20 C.F.R. §§ 416.920(e), 416.945(a)(2); Social Security Ruling ("SSR") 96-8p. If the claimant cannot perform his or her past relevant work or has no past relevant work, the ALJ proceeds to the fifth step and must determine whether the impairment prevents the claimant from performing any other substantial gainful activity. Moore v. Apfel, 216 F.3d 864, 869 (9th Cir. 2000).
The claimant bears the burden of proving steps one through four, consistent with the general rule that at all times the burden is on the claimant to establish his or her entitlement to benefits. Parra, 481 F.3d at 746. Once this prima facie case is established by the claimant, the burden shifts to the Commissioner to show that the claimant may perform other gainful activity. Lounsburry v. Barnhart, 468 F.3d 1111, 1114 (9th Cir. 2006). To support a finding that a claimant is not disabled at step five, the Commissioner must provide evidence demonstrating that other work exists in significant numbers in the national economy that the claimant can do, given his or her RFC, age, education, and work experience. 20 C.F.R. § 416.912(g). If the Commissioner cannot meet this burden, then the claimant is disabled and entitled to benefits. Id.
In this case, the ALJ determined at step one of the sequential process that Plaintiff did not engage in substantial gainful activity from the March 1, 2001, alleged onset date of disability through December 30, 2009. (AR 21.)
At step two, the ALJ determined that prior to July 20, 2007, Plaintiff had not had any medically determinable impairments and, thus, was "not disabled" on July 20, 2007, the date last insured. (AR 21-22. ) The ALJ also determined that since July 20, 2007, Plaintiff has had the following severe ...
