Leffler v. Sharp

After leaving a bar to escape the heat and noise, Leffler (plaintiff) climbed through an open window onto an adjacent rooftop, ignoring a nearby locked glass door stenciled "NOT AN EXIT," and fell through the roof — an area that had once been a terrace but was closed off as unsafe. Leffler sued the bar owner and building owners (defendants), arguing he was an invitee or licensee rather than a trespasser; the defendants moved for summary judgment, which the trial court granted, and Leffler appealed.
