Decision pattern

Since 2016, Judge Chau has issued 2,541 decisions. His approval rate has trended upward over the last decade, moving from 53% in 2016 to 74% in the most recent reporting period. This record reflects his consistent approach to evaluating evidence in disability claims.

Preparing for an SSDI hearing

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