In Howington v. Taiwan Semiconductor Manufacturing Co., Ltd., Judge DeMarchi ordered partial discovery production, excluding immigration-status data and denying requests 3–4.

Who this affects

The order affects the plaintiffs, TSMC and its named defendant entities, and applicants and employees whose information may appear in the requested records. TSMC must produce most data covered by RFPs 1 and 2 but need not produce the specified visa-related fields or data responsive to RFPs 3 and 4.

What happened

Howington v. Taiwan Semiconductor Manufacturing Co., Ltd. is a putative class action in which the plaintiffs allege that the defendants discriminated against people who are not East Asian, Taiwanese, Chinese, or citizens of Taiwan or China. They bring claims under 42 U.S.C. § 1981 and Title VII concerning hiring, promotion, termination, and workplace conditions.

The plaintiffs asked for applicant and employee information from four document requests, including demographic, hiring, promotion, performance, and termination data. The defendants objected that the information was difficult to access, should be limited to named plaintiffs, and included private information about other people, especially immigration-related information.

Judge Virginia K. DeMarchi ordered the defendants to produce data responsive to Requests 1 and 2, except for visa type and whether the defendants sought permanent labor certification or a green card for an employee. The judge did not require production responsive to Requests 3 and 4 and required the permitted production to be substantially complete by September 19, 2025.

Background

The plaintiffs filed a putative class action alleging that Taiwan Semiconductor Manufacturing Co. Ltd., TSMC North America, TSMC Technology, Inc., TSMC Arizona Corporation, and TSMC Washington, LLC (collectively, “TSMC” or “defendants”) engaged in an intentional pattern and practice of employment discrimination. The alleged discrimination concerned race, national origin, and citizenship, including discrimination in hiring, staffing, promotion, and retention or termination. The plaintiffs also alleged a hostile work environment. They asserted class claims under 42 U.S.C. § 1981 and Title VII, including disparate-treatment, disparate-impact, and hostile-work-environment claims. Certain named plaintiffs also asserted individual claims.

Discovery dispute

The parties asked the court to resolve a dispute concerning four requests for production, or RFPs, seeking applicant and employee data. RFP 1 sought information about people who applied for positions in the United States, including identity, race, national origin, citizenship, visa type, application details, interviews, offers, hiring, and information about people ultimately hired. RFP 2 sought information about United States employees, including identity, race, national origin, citizenship, visa type, employment history, positions, job levels, promotions, performance ratings, performance-improvement plans, and termination or resignation information.

RFP 3 sought information about employees for whom TSMC sought visas. RFP 4 sought information about employees for whom TSMC filed an Application for Permanent Employment Certification, known as a PERM application, or a green-card application.

The plaintiffs said the information was needed for statistical analyses supporting their pattern-or-practice claims and was available in standard human-resources data sources or existing Excel files. TSMC argued that the data was not readily accessible, that production should be limited to the named plaintiffs, and that the requests sought confidential information about thousands of people, including immigration-status information.

Court’s analysis

The court applied the discovery standard in Federal Rule of Civil Procedure 26(b)(1), which permits discovery of nonprivileged information relevant to a claim or defense and proportional to the needs of the case. The court was not persuaded that TSMC lacked standard applicant and employee data in readily accessible forms. It also rejected limiting production to the named plaintiffs, reasoning that such a limitation would not allow the plaintiffs to develop statistical evidence about disparities in hiring, staffing, promotion, and retention or termination decisions.

For RFPs 1 and 2, the court found that the requested information other than certain immigration-related data was reasonably necessary for the plaintiffs’ statistical analyses. The court recognized that the data included personally identifiable information about nonparties but found that their privacy interests could be protected by limiting access to the plaintiffs’ counsel and appropriate experts under the protective order, with safeguards against disclosure and use for purposes unrelated to the identified statistical analyses.

The court concluded that the plaintiffs had not explained why they needed each applicant’s or employee’s “visa type” or information about whether TSMC sought permanent labor certification or a green card for an employee. The court treated immigration status as sensitive information and found that the plaintiffs’ claims concerned race, national origin, and citizenship—not visa type or immigration status. For the same reason, the court found that the plaintiffs had not explained why they needed the detailed visa, PERM, and green-card information sought by RFPs 3 and 4.

Order

The court ordered TSMC to produce data from its human-resources data sources and Excel files responsive to RFPs 1 and 2, except for data showing visa type or whether TSMC sought a permanent labor certification or green card on an employee’s behalf. TSMC’s production had to be substantially complete by September 19, 2025. If TSMC claimed that it did not have or could not access an item within the permitted scope, it had to identify the item and explain why it could not be produced. The court stated that remaining disputes could be brought to its attention.

The court denied the plaintiffs’ request to compel production responsive to RFPs 3 and 4 and stated that TSMC was not required to produce that data. The order was entered by Judge Virginia K. DeMarchi, United States Magistrate Judge.
