Sprint Spectrum Realty Company, LLC v. Hartkopf, Jr.

Background

Sprint Spectrum Realty Company, LLC, the tenant, and William F. Hartkopf, Jr., the landlord, entered into a Personal Communication Services Site Agreement in or around August 1997. The agreement concerned Sprint’s use of space on Hartkopf’s roof for a personal communication services site. The parties later amended the agreement to permit installation and modification of certain components and to increase the rent.

Sprint asserted claims for declaratory judgment, breach of contract, breach of the duty of good faith and fair dealing, and specific performance. Hartkopf asserted counterclaims for declaratory relief, breach of contract, breach of the implied covenant of good faith and fair dealing, and unjust enrichment. The parties agreed that Sprint’s rooftop installation occupied more than 300 square feet, but disputed whether the agreement authorized that use and how much space above 300 square feet Sprint occupied.

Motion to Exclude Expert Testimony

In connection with summary judgment and trial preparation, Sprint moved under Federal Rule of Evidence 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc. to exclude the report and deposition testimony of Hartkopf’s expert, Neil K. Shirk. Shirk was a radio-frequency engineer with more than 30 years of engineering experience. Hartkopf retained him to analyze the operation, performance, configuration, and space requirements of electrical and electronic equipment installed on the rooftop.

Sprint argued that Shirk’s opinions were immaterial to the lease dispute and square-footage issue. It also argued that he was not qualified to interpret the lease, had not reviewed the Site Agreement, had not visited the property, relied on information lacking context, and used irrelevant radio-frequency setback information. Sprint further argued that his opinions were not based on sufficient reliable facts or data.

Legal Standard

Rule 702 permits expert testimony when specialized knowledge will help the fact finder understand the evidence or decide a disputed fact, the testimony rests on sufficient facts or data, the methods are reliable, and the expert reliably applied those methods to the case. The court described the two central considerations as relevance and reliability. Under Daubert, the court examines the principles and methods supporting an opinion rather than deciding whether the opinion itself is persuasive. Challenges that affect the testimony’s weight generally are for the jury rather than grounds for exclusion.

Court’s Analysis

The court found Shirk’s testimony relevant because he calculated how much rooftop space Sprint was using at particular times. Although the parties agreed that Sprint used more than 300 square feet, they disputed the precise amount above that threshold. The court also found Shirk’s opinions about radio-frequency setbacks relevant because they related to the space occupied by Sprint’s equipment in light of those regulations.

The court rejected Sprint’s argument that Shirk needed to interpret the lease. Hartkopf retained Shirk as an engineering expert, and his opinions addressed the factual question of how much space Sprint’s equipment occupied, not the meaning of the lease.

The court also found the opinions reliable. Shirk reviewed more than 22 drawing packages, photographs, structural calculations, radio-frequency-emissions reports, and reports concerning the rooftop space Sprint used. The drawing packages showed how equipment was configured, changed, removed, and reinstalled. The court concluded that these materials provided a scientifically valid basis for his opinions even though Shirk did not visit the roof. The court also ruled that the existence of allegedly contradictory material did not establish that his methods were unreliable. Those criticisms went to the weight of the testimony, not its admissibility.

Disposition

Judge Jacqueline Scott Corley denied Sprint’s motion to exclude Shirk’s expert report and deposition testimony. The court stated that the testimony was admissible, relevant, and reliable. The order disposed of Docket No. 90.
