In contrast, in jurisdictions with very weak respect for precedent, fine questions of law are redetermined anew each time they arise, making consistency and prediction more difficult, and procedures far more protracted than necessary because parties cannot rely on written statements of law as reliable guides. In jurisdictions that do not have a strong allegiance to a large body of precedent, parties have less "a priori" guidance (unless the written law is very clear and kept updated) and must often leave a bigger "safety margin" of unexploited opportunities, and final determinations are reached only after far larger expenditures on legal fees by the parties.
