Shakuntla Devi (predecessor of the petitioners). The reference was finally decided by the Reference Court vide judgment dated 6.10.1983.

When the matter came back to the Reference Court, Smt. Shakuntla Devi moved an application for becoming party in the reference, as earlier she did not submit any application either under Section 30 or Section 18 of the Act. Her application was allowed vide order dated 9.2.1983 and thereafter, the case was adjourned for evidence of the respective parties. When the evidence was in progress and respondents No.1 to 4 were producing certain documents, learned counsel for Smt. Shakuntla Devi objected for the same, to which learned counsel for respondents No.1 to 4 submitted that Smt. Shakuntla Devi has no locus standi in the case, as she did not file any reference either under Section 30 or Section 18 of the Act. After hearing learned counsel for the parties, vide order dated 22.5.1992, the Reference Court observed that Smt. Shakuntla Devi has no locus standi to raise such objection. This order has been challenged in the present revision petition.
