EC 7-2.

The bounds of the law in a given case are often difficult to ascertain. The language of legislative enactments and judicial opinions may be uncertain as applied to varying factual situations. The limits and specific meaning of apparently relevant law may be made doubtful by changing or developing constitutional interpretations, inadequately expressed statutes or judicial opinions, and changing public and judicial attitudes. Certainty of law ranges from well-settled rules through areas of conflicting authority to areas without precedent.
