Finin2min Summary - Section in 2 Minutes

Prevents proceedings from failing merely for mistake, defect or omission where they are in substance consistent with the Act and no prejudice is caused; it does not cure lack of jurisdiction or denial of natural justice.

Exact operative text

160. Assessment proceedings, etc., not to be invalid on certain grounds.-(1) No assessment, re-assessment, adjudication, review, revision, appeal, rectification, notice, summons or other proceedings done, accepted, made, issued, initiated, or purported to have been done, accepted, made, issued, initiated in pursuance of any of the provisions of this Act shall be invalid or deemed to be invalid merely by reason of any mistake, defect or omission therein, if such assessment, re-assessment, adjudication, review, revision, appeal, rectification, notice, summons or other proceedings are in substance and effect in conformity with or according to the intents, purposes and requirements of this Act or any existing law. (2) The service of any notice, order or communication shall not be called in question, if the notice, order or communication, as the case may be, has already been acted upon by the person to whom it is issued or where such service has not been called in question at or in the earlier proceedings commenced, continued or finalised pursuant to such notice, order or communication.

No direct Rule certified in Phase 1. Check notifications, circulars, forms and corresponding State law.

The mapping is a legal concordance, not a round-robin related-link list. It is limited to instruments certified in this phase.

Practical example

A notice quotes an incorrect sub-clause but clearly states facts, demand and jurisdiction and causes no prejudice. The substance-over-form saving is examined.

Professional alert

This curing provision cannot repair absence of jurisdiction, limitation failure or material denial of hearing.
