The opinion of the court was delivered by: Rosalyn M. Chapman United States Magistrate Judge
Plaintiff Claude Bonner, Jr., filed a complaint on February 9, 2009, seeking review of the Commissioner's decision denying his application for disability benefits. On June 30, 2009, the Commissioner answered the complaint, and on August 13, 2009, the parties filed a joint stipulation.
On September 20, 2006, plaintiff, who was born on April 21, 1967, applied for disability benefits under the Supplemental Security Income ("SSI") program of Title XVI of the Social Security Act ("Act"), claiming an inability to work since March 1, 2004, due to depression, hearing voices, and suicide attempts. Certified Administrative Record ("A.R.") 111-13, 375-77. The plaintiff's application was initially denied on February 27, 2007, and was denied again on May 23, 2007, following reconsideration. A.R. 46-52, 56-60. The plaintiff then requested an administrative hearing, which was held before Administrative Law Judge Mason D. Harrell, Jr. ("the ALJ") on July 1, 2008. A.R. 18-43, 63. On August 14, 2008, the ALJ issued a decision finding plaintiff is not disabled. A.R. 4-17. The plaintiff appealed the decision to the Appeals Council, which denied review on December 8, 2008. A.R. 1-3.
The Court, pursuant to 42 U.S.C. § 405(g), has the authority to review the decision denying plaintiff disability benefits to determine if his findings are supported by substantial evidence and whether the Commissioner used the proper legal standards in reaching his decision. Vasquez v. Astrue, 572 F.3d 586, 591 (9th Cir. 2009); Vernoff v. Astrue, 568 F.3d 1102, 1105 (9th Cir. 2009).
The claimant is "disabled" for the purpose of receiving benefits under the Act if he is unable to engage in any substantial gainful activity due to an impairment which has lasted, or is expected to last, for a continuous period of at least twelve months. 42 U.S.C. § 1382c(a)(3)(A); 20 C.F.R. § 416.905(a). "The claimant bears the burden of establishing a prima facie case of disability." Roberts v. Shalala, 66 F.3d 179, 182 (9th Cir. 1995), cert. denied, 517 U.S. 1122 (1996); Smolen v. Chater, 80 F.3d 1273, 1289 (9th Cir. 1996).
The Commissioner has promulgated regulations establishing a five-step sequential evaluation process for the ALJ to follow in a disability case. 20 C.F.R. § 416.920. In the First Step, the ALJ must determine whether the claimant is currently engaged in substantial gainful activity. 20 C.F.R. § 416.920(b). If not, in the Second Step, the ALJ must determine whether the claimant has a severe impairment or combination of impairments significantly limiting him from performing basic work activities. 20 C.F.R. § 416.920(c). If so, in the Third Step, the ALJ must determine whether the claimant has an impairment or combination of impairments that meets or equals the requirements of the Listing of Impairments ("Listing"), 20 C.F.R. § 404, Subpart P, App. 1. 20 C.F.R. § 416.920(d). If not, in the Fourth Step, the ALJ must determine whether the claimant has sufficient residual functional capacity despite the impairment or various limitations to perform his past work. 20 C.F.R. § 416.920(f). If not, in Step Five, the burden shifts to the Commissioner to show the claimant can perform other work that exists in significant numbers in the national economy. 20 C.F.R. § 416.920(g). Moreover, where there is evidence of a mental impairment that may prevent a claimant from working, the Commissioner has supplemented the five-step sequential evaluation process with additional regulations addressing mental impairments.*fn1 Maier v. Comm'r of the Soc. Sec. Admin., 154 F.3d 913, 914-15 (9th Cir. 1998) (per curiam).
Applying the five-step sequential evaluation process, the ALJ found plaintiff has not engaged in substantial gainful activity since September 20, 2006, his application date. (Step One). The ALJ then found plaintiff has the severe impairments of: "a psychotic disorder, [Listing] 12.03; a personality disorder, not otherwise specified, under [Listing] 12.08; and mixed substance abuse with evidence of alcohol use" (Step Two); however, plaintiff does not have an impairment or combination of impairments that meets or equals a Listing. (Step Three). The ALJ then found plaintiff can perform his past relevant work as a hand packer; therefore, he is not disabled. (Step Four). Alternately, the ALJ determined plaintiff is not disabled because he can perform a significant number of jobs in the national economy. (Step Five).
"'In Social Security cases, the ALJ has a special duty to fully and fairly develop the record and to assure that the claimant's interests are considered.'" Smolen, 80 F.3d at 1288 (citation omitted); Widmark v. Barnhart, 454 F.3d 1063, 1068 (9th Cir. 2006); see also Higbee v. Sullivan, 975 F.2d 558, 561 (9th Cir. 1992) (per curiam) ("We have long recognized that the ALJ is not a mere umpire at [an administrative hearing], but has an independent duty to fully develop the record...."). This duty exists regardless of whether the claimant is represented by counsel, Celaya v. Halter, 332 F.3d 1177, 1183 (9th Cir. 2003); Tonapetyan v. Halter, 242 F.3d 1144, 1150 (9th Cir. 2001), and it is "heightened where the claimant may be mentally ill and thus unable to protect h[is] own interests." Tonapetyan, 242 F.3d at 1150; Higbee, 975 F.2d at 562. "Ambiguous evidence, or the ALJ's own finding that the record is inadequate to allow for proper evaluation of the evidence, triggers the ALJ's duty to 'conduct an appropriate inquiry.'" Tonapetyan, 242 F.3d at 1150 (citations omitted); Webb v. Barnhart, 433 F.3d 683, 687 (9th Cir. 2005).
Plaintiff, who was represented by counsel at the administrative hearing, A.R. 18-43, contends the ALJ failed to properly develop the record because he did not request any information about the Social Security Administration's ("SSA") prior grant of, as well as any suspension(s) or termination of, SSI benefits to plaintiff, and plaintiff testified about receiving such benefits (A.R. 22). Jt. Stip. at 12:13-14:24, 15:24-16:4. Under the circumstances of this case, the Court agrees.
Under Social Security regulations, "a claimant's benefits are suspended upon incarceration, and after 12 months of continuous suspension, benefits are terminated." Stubbs-Danielson v. Astrue, 539 F.3d 1169, 1172 (9th Cir. 2008); 20 C.F.R. §§ 416.1325, 416.1335; see also Brennan v. Astrue, 501 F. Supp. 2d 1303, 1308-09 (D. Kan. 2007) ("Payment of SSI benefits is suspended effective with the first full month an individual is a resident of a public institution[,]... [and] benefits will be terminated 'following 12 consecutive months of benefit suspension for any reason... effective with the start of the 13th month after the suspension began.'" (citations omitted)). However, if a claimant is incarcerated for less than 12 consecutive months, "[b]enefits for which payments have been suspended will ...
