Metropolitan Magistrate Vijeta Singh rejected Jolly's plea to be allowed to intervene in the court proceeding and oppose the police application. Jolly had made the plea saying he had been directly affected in the matter as he had lost the 2008 assembly polls against Dikshit.
The magistrate dismissed his plea saying "the applicant (Jolly) has failed to satisfy the court in regard of his locus standi (to intervene)".
The court also said it would decide later whether the plea for withdrawal of case against Dikshit is as per the law.
The court, which was also scheduled to pronounce its order on Delhi police's plea for withdrawal of case against Dikshit, has now listed the matter for further arguments on April 28.
The magistrate, on the last date of hearing, had reserved the order on the application by Delhi Police saying she was "prima facie" satisfied that the plea for withdrawal of the case was maintainable and could be heard upon.
Jolly, in his plea filed by lawyer Anil Soni, had opposed Delhi Police decision to withdraw the case registered for the alleged violation of the Model Code of Conduct by Dikshit during the election, saying the code is same for everyone.
