The first question any trial attorney must be able to answer is: What is the theory of my case at trial? Once you've answered that, the next question to consider is: What is the theory of my case on appeal? The attorneys in Mahanuntawong v. Kittithanyaphak (D1d1 Jul. 9, 2021) no. A158610 (nonpub. opn.) had a pretty good answer to that question, but it came too late, and so the court held it was waived.
The court held the appellant forfeited any challenge to defects in the statement of decision by failing to object in the trial court, and forfeited the arguments that the award was excessive because it was not raised in a motion for new trial.
The moment a verdict or tentative decision is released is when an appellate strategy can take shape. But appellate issues may be waived beginning just days later, such as failing to cultivate the statement of decision, or failing to raise key issues in a new trial motion. This is a crucial time to consult appellate counsel.
