In which one of the following cases was it held that “only in case of triple Talaq Halala is mandatory…

In "Mrs. Sabah Adnan Sami v. Adnan Sami" (2010) it was held that halala, an intervening marriage, is required before the same couple remarry only where the earlier divorce was by triple talaq; where the divorce was a single irrevocable pronouncement, they could remarry without it. The other cases listed did not lay down this proposition.

Current law: Instant irrevocable triple talaq was invalidated in Shayara Bano (2017) and is void and illegal under section 3 of the 2019 Act; an ineffective pronouncement does not require an intervening marriage to restore a marriage it never dissolved. For covered Uttarakhand UCC persons, section 29 permits dissolution only under its statutory Part I process and section 30 governs remarriage after decree finality, subject to applicability/exclusions.
