1. If any Court before which a confession or other statement of an accused person recorded, or purporting to be recorded under section 164 or section 281, is tendered, or has been received, in evidence finds that any of the provisions of either of such sections have not been complied with by the Magistrate recording the statement, it may, notwithstanding anything contained in section 91 of the Indian Evidence Act, 1872 (1 of 1872), take evidence in regard to such non-compliance, and may, if satisfied that such non-compliance has not injured the accused in his defence on the merits and that he duly made the statement recorded, admit such statement.
2. The provisions of this section apply to Courts of appeal, reference and revision.

1. No finding sentence or order by a Court of competent jurisdiction shall be deemed invalid merely on the ground that no charge was framed or on the ground of any error, omission or irregularity in the charge including any misjoinder of charge, unless, in the opinion of the Court of appeal, confirmation or revision, a failure of justice has in fact been occasioned thereby.
2. If the Court of appeal, confirmation or revision is of opinion that a failure of justice has in fact been occasioned, it may
   1. in the case of an omission to frame a charge, order that a charge be framed and that the trial be recommenced from the point immediately after the framing of the charge.
   2. in the case of an error, omission or irregularity in the charge, direct a new trial to be had upon a charge framed in whatever manner it thinks fit:
      
      Provided that if the Court is of opinion that the facts of the case are such that no valid charge could be preferred against the accused in respect of the facts proved, it shall quash the conviction.

1. Subject to the provisions hereinbefore contained, on finding sentence or order passed by a Court of competent jurisdiction shall be reversed or altered by a Court of appeal, confirmation or revision on account of any error, omission or irregularity in the complaint, summons, warrant, proclamation, order, judgment or other proceedings before or during trial or in any inquiry or other proceedings under this Code, or any error, or irregularity in any sanction for the prosecution unless in the opinion of that Court, a failure of justice has in fact been occasioned thereby.
2. In determining whether any error, omission or irregularity in any proceeding under this Code, or any error, or irregularity in any sanction for the prosecution has occasioned a failure of justice, the Court shall have regard to the fact whether the objection could and should have been raised at an earlier stage in the proceedings.

No attachment made under this Code shall be deemed unlawful, nor shall any person making the same be deemed a trespasser, on account of any defect or want or form in the summons, conviction, writ of attachment or other proceedings relating thereto.
