Ors. (1979) 4 SCC 389, (2) Parsion Devi & Ors. Vs. Sumitri Devi & Ors. of Supreme Court dated 14th October, 1997 and (3) Thungabhadra Industries Ltd. Vs. The Government of Andhra Pradesh 1964 AIR 1372 . In each of them the distinction between an error on merits and an error on the face of record has been considered. An erroneous decision is held not reviewable but an error apparent on the face of the record is. As regards to the maintainability of the Review Petition under Order 47 of the CPC, the Counsel on behalf of respondent-wife drew my attention to 3 judgments; (1) K. L. Nandakumaran Nair Vs. K. I. Philip & Ors. (2001) 8 SCC 537, (2) Rajender Singh Vs. Lt. Governor, Andaman & Nicobar Islands & Ors. AIR 2006 SC 75 and (3) Sri Krishna Banwari Lal & Ors. Vs. Behari Lal Sri Krishna & Anr. AIR 1964 All 516 . In these judgments the parameters of when a Review Petition can be entertained has been set out. A reading of the 3 judgments together would show that when the Court has totally ignored the pleadings or has not dealt with a document which is brought on record and completely overlooked it and failed to consider it, it can review its own order. In the judgment in the case of Rajender Singh (supra) the Supreme Court has considered all these various aspects in para 15 of its order. In that case the Supreme Court considered that various materials which were placed on record were ignored and which if considered would have justified the claim of the appellant therein. That was the case where certain documents were not in possession of the parties which were shown at the time of the review and certain documents which were relied upon by the appellant were shown not to have been considered at all. The reasoning in para 15 would show that when a bulky compilation of 384 pages is placed before the Court and only page 3 thereof is considered, a Review Petition would be maintainable.
