CrPC 318: Section 318 of the Criminal Procedure Code

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.
