In Westfield Ins. Group v. Pure Renovations, LLC, 2019-Ohio-4773, 2019 Ohio App. LEXIS 4829, the Court of Appeals of Ohio considered whether the lower court properly granted the defendant’s summary judgment motion. In its motion, the defendant argued that the plaintiff could not prove that the defendant’s conduct was the proximate cause of the fire at issue because the plaintiff’s liability expert identified two possible causes of the fire. The Court of Appeals, finding issues of fact remain as to whether the defendant was solely responsible for both possible causes, reversed the summary judgment ruling. This case establishes that, in Ohio, if all likely causes implicate solely the defendant’s alleged negligent conduct, a plaintiff’s inability to identify, definitively, one cause of a loss does not necessarily preclude the plaintiff from establishing proximate cause.
