The secret to a successful personal injury practice may rest equally on the cases that are accepted and those that are not. The vast majority of serious injury cases do not present with the four sides of the perfect square necessary for success-liability, causation, damages and coverage-completed and aligned. We, as lawyers, analyze the cases, identify the problems and find practical solutions. If the client does not have a clear liability case, we must figure out rather quickly whether there are both the facts and the legal theories which will support recovery. This difficult initial decision is particularly challenging when it comes to premises liability cases.
