Lawyers know: Every case has a winner and a loser. Losses are due to the combination of facts and law, either of which might be unfavorable. Facts and law are static and case specific. Lawyers do not write the facts of a dispute, nor do they author the law upon which the dispute is resolved.
In the end, the legal system does not hold out legal professionals as guarantors of successful results. Calmly, deliberately, using the discovery and motions process very carefully, the legal malpractice attorney conveys rational perspective to the judges and juries who decide these claims.
