That’s what I have mentioned. Firstly, DJ must be presumed to have such inherent power. I have seen provisions in Cr.P.C. for rectification of errors in an order of the court, but I have not come across any provision in Cr.P.C. which permits rectification of errors in the revision petition itself. At the same time, I have seen courts permitting such rectification by moving an application for amendment (specially in the supreme court and high court).
Secondly, I have also advised you to check the rules made by your High Court which govern the criminal cases. Since the Cr.P.C. does not appear to be having such provisions, may be the relevant rules in your state may have some. So, better examine.
Thirdly, I said that if nothing helps, i.e., if the DJ refuses to allow you to amend your revision petition, then what other remedy have you got except to challenge the order of the DJ in High Court under Section 482 Cr.P.C., irrespective of whether it is a small thing or big thing? You have yourself mentioned that if the errors are not corrected, the petition becomes absurd. In such a situation, when the DJ does not permit you to amend, you have to take a call as to whether it is a small thing to ignore it (i.e., pursue the same revision petition with the same errors), or to consider it as a big thing and challenge the order of the DJ (refusing to amend petition) before HC.
Since I am replying the query in the abstract, i.e., without knowing the full facts, this is what I can state in the given circumstances.
