The Pennsylvania Supreme Court interpreted the scope of Section 331, which provides for service against non-resident owners of real estate, and concluded the word "involved" as used in the statute does not require a causal connection between the accident or injury and the real estate, but only the occurrence of the accident or injury on the real estate.
