Ask why a medical-negligence claim failed and you'll often hear "no breach." Look closer and the more common culprit is causation — the element most likely to be under-examined at the point a firm decides to commit.
Breach is necessary, not sufficient
Establishing that care fell below the standard is where assessment instinctively starts, and it matters. But a clear breach proves nothing on its own. A defendant can accept the care was substandard and still defeat the claim — if that substandard care didn't cause the harm.
Causation is where claims live or die
The question is deceptively simple: would the harm have occurred anyway? In many matters the underlying condition, its natural progression, or an intervening event would have produced the same outcome regardless of the breach. Causation has to be reasoned through the clinical facts — not assumed because a breach is obvious. It is the most demanding part of the analysis, and the one most often shortchanged when time is tight.
The standard of care sets the bar for both
Breach and causation are each measured against what a competent practitioner would have done, and what would reasonably have followed. Establishing that benchmark — and where the care sat against it — is clinical work as much as legal work, which is why a view formed without medical input is only ever half-formed.
Three failure modes to catch early
- A strong breach with weak causation — emotionally compelling, legally fragile.
- A real injury with an innocent cause — harm did occur, but not because of the breach.
- An incomplete record — the merits can't be judged at all, so the claim is run, or declined, blind.
Each is avoidable — but only if the hard questions are asked before the firm is committed, not after.
Assess causation first, honestly
The practical lesson from how claims actually fail: resolve causation early, and resist the pull of an obvious breach. A claim that survives an honest causation analysis is worth your time. One that doesn't was always going to cost more to learn that later.
