The lay evidence doctrine (Jandreau)

Key concept. Under the Federal Circuit’s decision in Jandreau v. Nicholson (2007), veterans are LEGALLY COMPETENT to testify about things they personally observed or experienced — without medical training. Pain, ringing in the ears, fatigue, sleep disturbance, memory loss, anxiety, panic attacks — these are all things VA must credit when reported by the veteran.

Why this matters

Some conditions, especially tinnitus and many mental health symptoms, are subjective. There is no medical test that can definitively prove or disprove them. The Lay Evidence Doctrine means your sworn statement describing the symptoms IS evidence — it does not need a doctor to validate it.

What lay evidence can establish

• Existence of symptoms (pain, ringing, fatigue, anxiety, etc.)
• Frequency and severity of symptoms
• Onset of symptoms (when they started)
• Continuity of symptoms over time (see continuity doctrine)
• Functional impact (what you can’t do because of the condition)
• Events you witnessed in service

What lay evidence CANNOT establish

• Medical diagnosis of a complex condition (“I have lumbar disc degeneration” — requires medical evidence)
• Medical nexus opinion (“My back pain was caused by carrying heavy rucks” — VA can credit the symptom history but needs a doctor to opine on causation)
