Here is an under-appreciated consideration in appellate procedure: If you are the party that prevailed at trial, and you collect on your judgment pending appeal, what's the worst that could happen? Would it surprise you to learn that the prevailing plaintiff could be ordered to make restitution "of all property and rights lost by the erroneous judgment or order," and could even have a money judgment imposed against it under Code of Civil Procedure section 908? This includes legal interest. And if enforcing the judgment caused the appellant to lose business profits, the judgment creditor can be liable for those losses, too.
That is very nearly what happened to the respondent in Dr. Leevil, LLC v. Westlake Health Care Ctr. (D2d6 Mar. 17, 2021) no. B304339 (non-pub.). A judgment-creditor absolutely can be liable in restitution to the judgment-debtor. And it would have here, too, had the appellant not stipulated to the remedy – a $5.7 million mistake. Ouch.
