Administrative instruction power guides tax authorities, subject to non interference in individual cases and parliamentary oversight.
Clause 239 grants the Board a broad administrative instruction power to issue binding orders and directions to income tax authorities for uniform administration, subject to safeguards: it cannot direct outcomes in individual cases or interfere with appellate discretion. The clause permits targeted interventions-general or special orders for assessment and collection, condonation of belated claims by non appellate authorities, and relaxation of deduction requirements where default is beyond the assessee's control and compliance occurs before completion of assessment-and requires reasons and parliamentary laying of certain relaxation orders.
