For the Respondents:

Based on the provided legal document, the key points are as follows:

1. The case concerns the admissibility of evidence presented by a non-litigating spouse on behalf of a litigating spouse in a civil proceeding (!) (!) .

2. The petitioner, the plaintiff, sought permission for her husband to adduce evidence on her behalf, which was initially rejected by the trial court (!) (!) .

3. The trial court's reasoning was that a person cannot give evidence on behalf of another, and that the husband could only be cited as a witness and examined as such (!) .

4. The appellate court emphasized that under the relevant provisions of the Evidence Act, a non-litigating spouse is competent to testify for the litigating spouse without requiring a separate power of attorney (!) (!) .

5. The court clarified that the competency of a witness refers to their capacity and qualification to give evidence, and that Section 120 of the Evidence Act permits spouses to testify for each other in civil cases without additional authorization (!) (!) .

6. The appellate court found that the trial court failed to consider Section 120 of the Evidence Act, which led to an unjustified rejection of the petition. Consequently, the order was set aside, and the petition was allowed (!) (!) .

7. The decision underscores that a spouse's testimony is admissible and sufficient to support the case without the need for a power of attorney or specific authorization, provided the spouse is competent under the law (!) (!) .
