The Code of Criminal Procedure, 1973
§318 — Procedure where accused does not understand proceedings
If the accused, though not of unsound mind, cannot be made to understand the proceedings, the Court may proceed with the inquiry or trial; and, in the case of a Court other than a High Court, if such proceedings result in a conviction, the proceedings shall be forwarded to the High Court with a report of the circumstances of the case, and the High Court shall pass thereon such order as it thinks fit.
