2. Mr.Ashish Surana and Mr.Rakesh Dubey, learned counsel for the petitioners, would submit that this Court in para-12 of the order under review has held that Revenue Book Circular has no force of law, but in view of the notification dated 23rd November, 2001 it can be said to be force of law. They would further submit that the Commissioner could not have been granted permission for review to the Collector, but the Commissioner has granted permission for review and on that basis, the Collector reviewed and set aside the order passed by the Additional collector permitting exchange of service land, which has rightly been set aside by the Board of Revenue and the writ petition as framed and filed by the State under Article 227 of the Constitution of India was not maintainable, which has been entertained and order under review has been passed. Therefore, the review petitions deserve to be allowed.
