AMI (P) and Alcoa (D) entered into a contract to design and fabricate an automated greenline handling system. During the construction, P submitted invoices for work not included in the contract. D processed the invoices for payment. They eventually disagreed over two invoices totaling about $500,000. P submitted them to the attention of D’s procurement manager at the end of the project. The manager then consulted the employees involved, and a meeting was held in which handwritten contemporaneous notes were kept. P sued D for the unpaid invoices and D moved in limine to exclude portions of the memoranda and a letter involving those meetings. The district court ruled portions of 13 items inadmissible.
