A division bench of Madras High Court passed this Judgment.

From Para 16, (How simple mistakes can turn evidence into trash!)

16. At this juncture, the learned Counsel for the petitioner would invite the attention of this Court to Ex-R.4 in H.M.O.P. No.702 of 2021 – Screenshot of Whatsapp Chat dated October 17, 2017, and would argue that the respondent herself admitted that everything is her fault and apologised to the petitioner about 10 days before making Ex-R.5 – Complaint and that in such a scenario, Ex-R.5 – Complaint could only be a false one. This Court has perused Ex-R.4 – Screenshot. It appears that the petitioner has received a message from a contact whom he has saved as “ANU”. The respondent has denied the said message in her cross-examination. The burden is upon the petitioner to prove Ex-R.4 –Screenshot. It is true that the Indian Evidence Act, 1872 would not be strictly applicable to family court matters, in view of Section 14 of the Family Courts Act, 1984. But, said Section 14 does not dispense with the burden of proof. The burden remains upon the petitioner. But the petitioner has failed to discharge the said burden. The petitioner has not taken any steps to prove that the said contact from which he received such a message, is his wife / respondent. Hence, the argument of the learned Counsel for the petitioner deserves to be rejected.

From Para 17,

17. Be that as it may, whether the averments contained in Ex- R.5 – Complaint are true or not is a matter for police investigation and the truth can be found only in the trial. But there was no investigation in the first place. The averments remain unestablished. The averments made in Ex-R.5 are of such nature that unless proved, they amount to defamation, which in turn constitutes to mental cruelty. If really the said averments are true, the respondent ought to have taken prudent steps to prove her averments when the petitioner failed to reunite with her. Unsubstantiated or uncorroborated defamatory averments made in Ex-R.5, causes stigma and mental agony to the petitioner as well as his family, and in the facts and circumstances of this case amounts to cruelty.

From Paras 20-21,

20. As elaborated above, the unestablished sexual allegations made by the respondent against the petitioner and his father, amounts to cruelty and thus, the petitioner has made out a case under Section 13 (1) (i-a) of H.M. Act. Points for consideration arising in these Civil Miscellaneous Appeals are answered accordingly. The petitioner is thus entitled to a Decree of divorce.
21. It is learnt that the petitioner is paying a maintenance of Rs.25,000/- to the respondent and his 8 year old child (who is under the custody of the respondent) every month. Considering the facts and circumstances of this case, especially the stand taken by the respondent that she is ready and willing to let go of the past and resume her marital life with the petitioner, this Court is of the view that though divorce is granted in favour of the petitioner, maintenance rights of the respondent shall remain unaffected.
