Impracticable means inability to perform a specific course of action in practice, limiting feasibility and legal enforceability. Impracticable denotes that a proposed course of action or performance is not practicable in the available circumstances-incapable of being performed by the means employed or at command-so that, although theoretically possible, it is rendered unworkable, excessively difficult, or impossible in practice; the term is stronger than inexpedient and distinct from impractical, which denotes general unreasonableness.
