Recent Defense Verdict(s)

Plaintiff alleged falling along a newly constructed Delivery Drop Off lane and claimed it was defective which caused her to fall. Corey and his partner, Diane Robben, successfully argued the Delivery Drop Off Lane was reasonably safe as constructed and the plaintiff’s fall was an accident and due to her failure to keep a careful lookout.
