The plaintiffs, Mr. and Mrs. Stewart, hired architect William Gruber to design and oversee the construction of a multi-unit apartment complex. After the project was completed, the Stewarts alleged that the building suffered from multiple structural issues, including uneven flooring, cracked walls, and misaligned framing.

In the case of UGI Sunbury LLC v. A Permanent Easement for 1.7575 Acres, 949 F.3d 825 (3d Cir. 2020), the testimony of a Pipelines Expert Witness played a central role in evaluating claims for damages associated with a natural gas pipeline easement. This case addressed the admissibility and reliability of expert testimony related to property value diminution caused by perceived risks of pipeline proximity—commonly known as “stigma damages.”

Background of the Case

UGI Sunbury LLC, a natural gas company, constructed a 35-mile pipeline in central Pennsylvania. Under the Natural Gas Act, UGI obtained the legal right to take easements by eminent domain across several privately owned parcels of land. The dispute in this case arose from one such property, where the landowners claimed that the presence of the pipeline significantly diminished the value of their land—not due to physical damage, but because of public perception and fear related to the potential danger of a high-pressure natural gas line.
