Decision pattern

Over your 9 years on the bench, Judge Harrell has seen his approval rates fluctuate, moving from a low of 53% in 2017 to a peak of 73% in 2020. Following a period of adjustment in 2022, his approval rate has stabilized at 69% throughout 2023 and into 2024. This recent trend shows a return to higher approval levels compared to his earlier career years. The current pattern reflects a steady approach to evaluating evidence in your disability claim.

Preparing for an SSDI hearing

The guidance below applies to any SSDI hearing, not specifically to Judge Harrell Jr.'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.
