Grove v. Port Authority of Allegheny County

Summary

The Pennsylvania Supreme Court reviews whether the trial court committed reversible error by declining to instruct the jury on negligence per se and specified pedestrian-related Vehicle Code provisions. The Court holds that the Commonwealth Court did not identify a fundamental error or prejudicial omission warranting a new trial, where the jury found the plaintiff negligent and apportioned causal negligence equally between the parties. The decision addresses negligence per se, comparative negligence, factual cause, and harmless error in jury instructions.

Holdings

1. The omission was harmless error because the jury found Grove negligent. A negligence per se instruction concerns duty and breach, and does not control the separate inquiries of factual cause or comparative-fault apportionment.
2. The Commonwealth Court erred by ordering a new trial without affirmatively finding a fundamental error or actual prejudice; speculation that the instructions could have influenced the jury was insufficient.

Questions Presented

1. Whether the trial court's failure to give a negligence per se instruction based on Vehicle Code provisions governing pedestrian duties and the overtaking of vehicles constituted prejudicial error.
2. Whether the absence of the negligence per se instruction could affect the jury's apportionment of factual cause or comparative negligence after the jury found Grove negligent.
3. Whether the Commonwealth Court abused its discretion or committed legal error by ordering a new trial based on the instructional omission.
