There is an important point of trial practice about filing dispositive motions in limine in Tung v. Chicago Title (D1d3 Apr. 28, 2021) no. A151526 (published). That point is: Don't. The same point is made about relying on nonstatutory motions for judgment on the pleadings: Here is the quote to put in your opposition: "[W]e caution trial judges to be wary when choosing to decide an in limine motion that, no matter how captioned, functions as a nonstatutory motion for judgment on the pleadings, particularly when the motion is filed on the eve of trial. Doing so, under circumstances like those presented here, is a recipe for reversal."
Finally, there is also an excellent tip for expediting an appeal of an early catastrophic trial ruling and avoiding judgment collection pending appeal: dismissing remaining trivial claims (with prejudice), and stipulating to the prevailing party's fees and costs providing enforcement is to be stayed pending appeal. This was a shrewd move by appellant's counsel here, who served their client well.
