A reasonableness-only state for fees
Compare Washington to a state like New York, which applies a hard statutory sliding scale to medical malpractice attorney fees specifically. Washington has no equivalent figure anywhere in its rules — the fee simply must be reasonable under RPC 1.5, assessed case by case, for both ordinary personal injury and malpractice claims.
A consistent philosophy, not a coincidence
Washington struck down its own legislative noneconomic damages cap as unconstitutional in 1989, holding that the amount of damages is a question for the jury, not a statutory formula. That same resistance to legislative limits carries through to attorney fees: a 1995 bill to cap personal injury contingency fees by statute never passed either, leaving RPC 1.5's reasonableness standard as the sole governing rule on both fronts.
Two separate questions, both left uncapped
In a state that caps both damages and fees, the two questions interact: a fee percentage applies to a recovery that's already been reduced to a statutory ceiling. Washington's situation is simpler — neither cap exists for ordinary personal injury claims, so both the damages a claimant recovers and the percentage the attorney charges on that recovery are determined without a legislative ceiling on either end.
A narrow, genuine exception elsewhere
Washington does draw a real distinction for workers' compensation, where attorney fees are governed by a specific statute (RCW 51.52.120) rather than RPC 1.5's general standard. That exception doesn't extend to ordinary personal injury or medical malpractice contingency fees, which remain governed solely by the reasonableness test.
