Plaintiffs called [Bob Rinaldi](https://expertwitnessprofiler.com/expert-witness/Bob-Rinaldi/1574703) as an expert on industry standards in the field of equipment financing and leasing. Defendants objected during trial to the relevance of his testimony to the ultimate legal question of whether the AFA’s “absolute and unconditional” clause requires payment of the entire balance. ## **Equipment Financing Expert Witness** [Bob Rinaldi](https://expertwitnessprofiler.com/expert-witness/Bob-Rinaldi/1574703) began his career in the equipment finance and leasing industry in or about 1984. In 2018, he founded Rinaldi Advisory Services. He has also been a member of and held various leadership positions in industry trade groups, including Equipment Leasing and Financing Association (ELFA) and National Equipment Finance Association (NEFA).

But the Court may, to the extent that it reaches parol evidence, consider Rinaldi’s opinion that “absolute and unconditional” clauses are, in fact, customary in the equipment leasing and financing industry, and his opinion about how such terms are commonly understood. ## **Held** In sum, the Court overruled Defendants’ objection to Bob Rinaldi’s testimony. ## **Key Takeaway** While an expert is not permitted to offer his opinion on how, as a matter of law, a contract should be construed, it should be noted that expert testimony may be allowed when it addresses custom and practice in a particular trade as it relates to a contract dispute. ## **Case Details:** --- ## **You Might Also Like** ![Industrial Hygiene Expert's Contaminated House Theory Admitted](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/05/blog-pic-640X480-2026-05-22T191941.479.jpg) [**Industrial Hygiene Expert’s Contaminated House Theory Admitted**](https://expertwitnessprofiler.com/equipment-financing-expert-allowed-to-opine-on-custom-and-practice/industrial-hygiene-experts-contaminated-house-theory-admitted)![Correctional Healthcare Expert Was Allowed to Opine on Drug Addiction](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/05/blog-pic-640X480-2026-05-22T174929.135.jpg) [**Correctional Healthcare Expert Was Allowed to Opine on Drug Addiction**](https://expertwitnessprofiler.com/equipment-financing-expert-allowed-to-opine-on-custom-and-practice/correctional-healthcare-expert-was-allowed-to-opine-on-drug-addiction)![Accident Reconstruction Expert Not Allowed to Opine on Statutory Violation](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/05/blog-pic-640X480-2026-05-22T142444.026.jpg) [**Accident Reconstruction Expert Not Allowed to Opine on Statutory Violation**](https://expertwitnessprofiler.com/equipment-financing-expert-allowed-to-opine-on-custom-and-practice/accident-reconstruction-expert-not-allowed-to-opine-on-statutory-violation)![Fire Investigation Expert Was Allowed to Opine on UL Listing](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/05/blog-pic-640X480-2026-05-21T150819.636.jpg) [**Fire Investigation Expert Was Allowed to Opine on UL Listing**](https://expertwitnessprofiler.com/equipment-financing-expert-allowed-to-opine-on-custom-and-practice/fire-investigation-expert-was-allowed-to-opine-on-ul-listing)![Pulmonary Medicine Expert's COPD Opinions Admitted](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/05/blog-pic-640X480-2026-05-20T195112.411.jpg) [**Pulmonary Medicine Expert’s COPD Opinions Admitted**](https://expertwitnessprofiler.com/equipment-financing-expert-allowed-to-opine-on-custom-and-practice/pulmonary-medicine-experts-copd-opinions-admitted)
