Slip Opinion
Cal. Ct. App.Jun 26, 2025Background
- Sophie Shen sued her brother Weiping Xia over her $1.2 million investment in Western Water Corporation (WWC), claiming Xia promised her a 45% ownership interest but failed to pay her share from a $100 million sale of the company.
- Shen alleged Xia did not inform her of the sale or distribute sales proceeds; after learning of the sale in 2018, she initiated litigation.
- After a 15-day trial, Shen prevailed on her conversion claim and was awarded $21 million in damages; there were also findings relevant to a promised $10 million settlement, but Shen ultimately elected remedies on the conversion claim.
- Xia filed postjudgment motions for a new trial, terminating sanctions for alleged discovery violations (specifically, Shen's failure to timely produce certain WeChat messages), and to stay enforcement of the judgment.
- The trial court denied all Xia's postjudgment motions except for monetary sanctions relating to the costs of filing the motion over discovery violations, finding the nondisclosure was not willful.
- Xia appealed, principally contesting the denial of his motions for new trial, sanctions, and the admission of bank account evidence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether newly disclosed WeChat texts warranted new trial | Not newly discovered; defendant had opportunity to use at trial | Texts were critical new evidence withheld during discovery | Not newly discovered—defendant chose not to admit them |
| Whether Shen's nondisclosure amounted to proceeding irregularity | No material prejudice; content not outcome determinative | Withholding prejudiced ability to fully defend at trial | No prejudice or material effect on defendant's rights |
| Whether discovery violation was willful, meriting terminating sanctions | Mistake, not willful concealment | Nonproduction was intentional and harmful | No evidence of willfulness; monetary sanction only |
| Admissibility of evidence regarding bank account Xia controlled | Relevant to show control over sale proceeds | Prejudicial, lacked sufficient relevance | Relevant and probative; no abuse of discretion in admission |
