On April 27, 2023, the Florida Supreme Court issued an opinion in which it further amended Fla. R. Civ. P. 1.530 to require motions for rehearing to preserve for appeal challenges based upon a trial court’s “failure to make required findings of fact” (rather than “the sufficiency of trial court’s findings”). The rule took effect immediately and is now applicable in all instances, not just to final judgments.
