Rectification of mistakes apparent from the record: updated authority scope, procedural safeguards, and prescribed timelines ensure corrective relief.
Clause 287 empowers income-tax authorities to rectify mistakes apparent from the record by amending orders and specified intimations, subject to the exclusion of matters already considered in appeal or revision. Rectification may be initiated suo motu or on application, but any amendment increasing liability requires prior notice and a reasonable opportunity to be heard and must be made by written order. Reductions of liability trigger refund obligations, increases trigger prescribed demand notices, and the power is constrained by a prescribed limitation period and a statutory timeline for disposal of applications.
