Statutory text
Bare law
(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.
Key takeaways
Substance over form
A mistake, defect or omission alone does not invalidate a substantially conforming assessment, notice, appeal or other listed proceeding.
Service challenge
Service cannot later be questioned if the addressee acted on the communication or did not raise it at or in an earlier proceeding.
Not a cure for every flaw
The section requires substantial conformity; it does not automatically validate a proceeding lacking legal substance.
