Why File A Post-Trial Motion?
2. Preserve issues/avoid waiver for appeal. In many states, a defendant who lost at trial must raise certain issues by way of a post-trial motion in order to preserve the right to raise that issue on appeal. That is increasingly true of punitive damage verdicts the defendant believes are excessive under federal constitutional law. A growing number of courts around the country are concluding that an excessiveness challenge may only be raised on appeal if the defendant has first filed a new trial motion on that ground.
3. Create a record for appeal. The cardinal rule of appellate practice is: if it's not in the record, it doesn't count. (See Ch. 2A, Imre & Schiavelli, Preserving the Record for Appeal, California Civil Appellate Prcatice (CEB 2005). Often, filing a post-trial motion is the only way to get a critical fact, issue or error into the record. Otherwise, the appellate court probably won't not consider it, even if it wanted to.
4. Strategic advantages. Defendant’s settlement leverage is usually at its lowest point just after the jury has rendered a large verdict. Many plaintiffs consider a judgment, however exorbitant, to be “money in the bank.” Strong, tightly-constructed post-trial motions can help bring the opponent back down to earth, forcing plaintiffs’ counsel to confront the weaknesses in his or her case. And often, a post-trial motion serves a secondary strategic purpose: to get a preview of plaintiff’s arguments on appeal. This can provide a distinct tactical advantage when it comes to preparing the first appellate brief.
