Court not allowing HLRs to be brought on record. Waiving service suo moto. Threat of default dismiss

As Appellant I want to bring HLRs of deceased parties on record. Court not allowing this. Not allowing service on party ruled neccessary party by predecessor bench. Court waiving service on respondents suo moto after itself ordering issue of notice earlier. No change in circumstances meriting reversal of earlier stand. Forcing Appellant to start final hearing of Appeal without bringing HLRs on record on threat of "dismissal for default" using cover of 'High Court time bound". WP filed against this (Court intimated yet order is "adjourned for passing dismissal order") but dismissal will make WP infructious. Restoration Appln. If made before Appellate Court (dismissal court) will mean (1) payment of cost (2) arguing without HLRs on record. "Catch 22" situation. Can restoration Appln be made directly to High Court. If so, under which provision of law and any citations available on this. Matter at Mumbai. Looking forward to valuable advice from lawyers with knowledge / experience on such a situation.
