It’s that time of year when few court decisions are issued, the quiet stretch after the holidays. Yet, on December 26, 2019, the Ninth Circuit Court of Appeals released an important ruling in Zuniga v. Commissioner of Social Security, a case that continues to shape how Social Security disability appeals are reviewed.
Let’s break it down. 👇
Background of the Case
Zuniga appealed the denial of her Social Security disability benefits after two remands from the district court. By the time the case reached the Ninth Circuit, three major issues were at stake:
The credibility of subjective symptom testimony
The weight given to medical opinions
Compliance with remand orders
1. Credibility of Subjective Symptom Testimony
Zuniga argued that the Administrative Law Judge (ALJ) unfairly discredited her testimony about the severity of her symptoms.
Using the two-step Vasquez test, the ALJ:
Acknowledged that Zuniga’s impairments could cause her symptoms.
Found inconsistencies between her statements, daily activities, and the medical evidence.
These inconsistencies led the ALJ to discount her credibility — a reminder that even consistent medical complaints must align with daily functioning and objective findings.
2. Weight of Medical Opinions
The ALJ also rejected opinions from Zuniga’s treating physicians—Drs. Rubin, Boorstein, and Lee—citing:
Lack of objective medical support
Overreliance on Zuniga’s self-reported symptoms
Contradictions from daily activities and notes from a treating pharmacist
This demonstrates how courts continue to give deference to the ALJ’s discretion in weighing evidence, especially when treatment notes or daily activities appear inconsistent with reported limitations.
3. Compliance with Remand Orders
Zuniga further argued that the ALJ failed to comply with prior district court remand instructions — particularly regarding conflicting medical reports.
However, the Ninth Circuit upheld the ALJ’s decision, concluding that the remand instructions were adequately followed and that the findings were supported by substantial evidence.
Why Zuniga v. Commissioner Matters
This case is a masterclass in appellate deference. It highlights:
The limited scope of appellate review in Social Security cases
The importance of consistent medical documentation
How daily activities can significantly influence credibility and outcomes
In short, when the ALJ’s decision is supported by “substantial evidence,” appellate courts rarely overturn it.
Q&A: Lessons for Practitioners
Q: What can claimants learn from this case?
A: Ensure medical documentation aligns with claimed limitations. Any inconsistencies — even small ones — can weaken credibility.
Q: How can attorneys strengthen appeals?
A: Focus on building a clear record that bridges subjective testimony with objective findings. Reconcile any discrepancies early in the process.
Q: What role do daily activities play?
A: They often serve as a reality check for credibility. Activities suggesting higher functional ability can undermine claims of severe impairment.
Final Takeaway
Zuniga v. Commissioner of Social Security underscores the importance of cohesive, evidence-based advocacy in disability cases. Whether preparing a hearing brief or an appellate argument, practitioners should focus on aligning:
Claimant testimony
Medical opinions
Objective findings
