You know that the deadline to appeal may be extended if you file a posttrial motion. But beware: the extension does not apply if your posttrial motion turns out to be “invalid.” That very nearly happened in Arega v. Bay Area Rapid Transit Dist. (D1d3 Sep. 14, 2022 no. A163266) -- Cal.Rptr.3d --- (2022 WL 4232631) after the filed a motion to vacate under Code of Civil Procedure section 473(b) on grounds of inadvertence, surprise, mistake, or excusable neglect.
Fortunately for the appellants, the Court of Appeal held that a section 473 motion to vacate is still “valid” to extend the time to appeal, so long as it is filed within section 473’s outer six-month deadline. And that is the case even if the trial court denies the section 473 motion for not being filed sooner.
Comment: Posttrial procedure gets confusing, and dangerous. If this were a motion for new trial, my advice would be: file the appeal now. That is because you get the best of both worlds: you have safely preserved your right to appeal, and because the motion for new trial is a collateral proceeding, the trial court may hear and decide it despite the pending appeal. Win-win.
But the same is not necessarily true with all posttrial motions. On JNOV motions, there is a split of authority. And motions to vacate cannot be heard when an appeal is pending.
So it is very important to carefully and timely prepare and file posttrial motions if you are relying on them to extend the time to appeal.
