District and Session Judge P C Jain rejected the application. After hearing the final arguments on the application on May 10, the court had reserved judgement for today.
The court also extended his judicial custody till May 19.
In the application, Rathore had said that his detention in the case was illegal as there were no grounds for his detention so it should be cancelled.
Rathore, a former BJP minister, was arrested by the CBI on April 5 in connection with the Dara Singh fake encounter case of October 2006.
