Title Suit of Partition of a house property between two co-owners

A title suit on partition of a joint property having two co-owners with equal ownership has been filed by one of the two co-owners as plaintiff on 4th January 2021.just upon filing the case, the plaintiff has been granted a temporary ad-interim injunction under order 39 rule 1 & 2 read with section 151 of CPC, for a period of one month expiring on 3rd Feb 2021 without giving any opportunity to the defendant of being heard. But unfortunately the summon of the main case has not yet been served to the defendant by the Civil Court. But the injunction is continuing and hearing dates are being fixed by the Learned Court once in every month. I want to know what is the time limit for the Court to serve summon to the defendant. In case summon is not served to the defendant within 90 days from the date of filing the case, can the case be treated as dismissed / null and void ? Without any summon being served to the defendant and without any progress of the main partition suit how can the case /hearing of the injunction case continue for months together? Is it not a gross violation of the law of the land? It is also not understood how come a senior division Judge is allowing such illegal thing / affair of the business ? Is there any law /rule to point out this irregularity and dismiss /invalidate this sort of false case? If such laws exist in India please refer the same under which petition can be made to the Judge for invalidating the main title suit along with the injunction appeal
