Kaiser Aluminum Warrick, LLC v. US Magnesium LLC

Background

Kaiser Aluminum Warrick, LLC alleged that U.S. Magnesium, LLC breached a 2020 contract to supply magnesium. U.S. Magnesium asserted a force-majeure defense, arguing that unexpected equipment failures and related problems made it impossible to perform. The opinion identifies a broken turbine blade and a lightning strike that disabled a generator as among the events that led to downstream effects and ultimately caused U.S. Magnesium to stop producing magnesium in spring 2022. Fact discovery was scheduled to close on August 31, 2023.

Discovery Dispute

Kaiser sought discovery about the equipment failures, their causes, and the maintenance and repair of the affected equipment, including related expenditures. The court stated that this information was relevant to whether the failures were unforeseeable and beyond U.S. Magnesium’s reasonable control, which are requirements of the asserted force-majeure defense.

Kaiser also requested broader corporate financial information, including company-wide financial statements, the general ledger, and the trial balance from 2018 to the present. Kaiser intended to argue that U.S. Magnesium had not spent enough on maintenance and repairs and instead had invested in a lithium plant and paid dividends to its parent company, Renco Group Inc. U.S. Magnesium opposed this broader discovery as irrelevant and disproportionate.

Court’s Analysis

Under Federal Rule of Civil Procedure 26(b)(1), discovery may cover nonprivileged information relevant to a claim or defense and proportional to the needs of the case. The court explained that discovery relevance is broader than trial admissibility, but that courts may limit discovery when its burden or expense outweighs its likely benefit.

The court noted that U.S. Magnesium was not claiming it lacked the financial ability to pay for repairs and maintenance. Instead, U.S. Magnesium relied on the unusual nature of the equipment failure, which its engineers had never seen before, and on the unexpected lightning strike and resulting effects. The court concluded that information about investment in and spending on maintenance and repairs was relevant and discoverable. By contrast, decisions about investing in a lithium plant or issuing dividends were well beyond what was relevant to determining whether the equipment failures were unforeseeable and beyond U.S. Magnesium’s control. The court also found that any marginal relevance of the company-wide financial information did not make the information proportional to the needs of the case.

Disposition

The court denied Kaiser’s motion to compel production of U.S. Magnesium’s corporate-wide financial statements, general ledger, and trial balance. The order did not state that all of Kaiser’s discovery requests were denied; it distinguished the denied corporate-wide financial discovery from information about maintenance and repair spending.

Judge

The order was signed by Katharine H. Parker, United States Magistrate Judge.
