Mistaken idea “Impracticable means expensive or inconvenient”

Mistaken reasoning: This mistake treats implementation burden or old records as proof that retrospective application cannot be performed.

Updated Aug 21, 2026 Review due Nov 8, 2026

Why this is mistaken

Burden is not the definition. Document reasonable efforts and test whether the required application is impossible, depends on unsubstantiable historical intent, or requires estimates that cannot be separated from hindsight. The conclusion can differ by period.
