ALJs are independent decisionmakers; aggregate statistics describe past patterns, not predictions of how any individual case will be decided. Information here is provided for hearing preparation, not as legal advice.
Approval rates
Comparing a judge's performance requires looking at both lifetime averages and recent trends. While the Chicago Hearing Office maintains a recent approval rate of 56%, your judge's latest reporting period shows an approval rate of 46%. With 19,986 lifetime decisions, the data provides a statistically significant look at his history on the bench. These figures reflect historical trends rather than a fixed outcome for your hearing.
Office- and national-level breakdowns of fully favorable vs denial rates aren't currently published by SSA in the per-office disposition data. The judge's own breakdown is the detail we have today.
Approval rate over time
Year-over-year approval rate across Judge Mellman's docket. Annual rates fluctuate with the mix of cases SSA assigns; the longer-run pattern is more informative than any single year.
Decision pattern
Over his 10-year tenure, your judge has seen his approval rates fluctuate. After starting at 31% in 2016, the rate climbed to a peak of 51% in 2024 before settling at 46% in the most recent period. This trend indicates a shift in his decision-making approach over time, moving away from the lower approval rates observed during his first few years. The recent data suggests a more moderate pattern compared to his early career.
Preparing for an SSDI hearing
The guidance below applies to any SSDI hearing, not specifically to Judge Mellman's bench. Judge-specific preparation guidance requires a corpus of public Appeals Council decisions involving each judge, which we haven't built yet.
- Bring a clean treating-physician record. Longitudinal primary-care or specialist notes spanning the disability period, with consistent symptom documentation, are typically the strongest evidence at hearing. A single month's records usually aren't enough.
- Don't rely on consultative exams alone. If your medical evidence is built primarily around a one-time CE finding, expect detailed questioning. Supplement with treating-source statements where possible.
- Prepare for daily-activity questions. Have honest, specific answers about a typical day. Answers that conflict with the medical record (in either direction) tend to hurt credibility.
- Expect transferable-skills probing. A vocational expert will usually testify about jobs available to someone with your limitations. Your representative should be prepared to cross-examine.
