In one sentence

In Yuan v. Eightfold AI, Judge Martinez-Olguin denied Eightfold’s motion to dismiss, ruling Massachusetts law governs Yuan’s state-law claims.

Who this affects

Tanggang “Dan” Yuan’s Massachusetts state-law claims against Eightfold AI Inc. were allowed to proceed past Eightfold’s motion to dismiss.

What happened

In Yuan v. Eightfold AI Inc., Tanggang “Dan” Yuan alleged that Eightfold violated Massachusetts laws concerning sick time, paid family and medical leave, and wages. Yuan worked remotely from Massachusetts, lived there throughout his employment, and was terminated after requesting leave related to the premature birth and medical treatment of his twins.

Eightfold argued that Yuan’s employment agreement required California law and that his Massachusetts claims therefore should be dismissed. The court found that the laws of Massachusetts and California could provide different damages and other remedies. It also found that the agreement’s California-law provision did not clearly refer to statutory claims and that Massachusetts had the stronger connection to the dispute because Yuan worked and lived there and Eightfold withheld Massachusetts taxes.

Judge Araceli Martinez-Olguin denied Eightfold’s motion to dismiss. The court concluded that Eightfold had not shown that California law governed the dispute, so Yuan’s Massachusetts claims were not dismissed at this stage.

Case
Yuan v. Eightfold AI Inc. · No. 3:24-cv-04238
Judge
Martinez-Olguin
Date
May 30, 2025

Background

Tanggang “Dan” Yuan accepted a job offer from Eightfold AI Inc. in November 2021 and began working 11 days later. The opinion states that Eightfold’s principal place of business was in California, while Yuan lived and worked remotely from Massachusetts throughout his employment. Eightfold deducted Massachusetts state taxes from Yuan’s paychecks.

In May 2022, Yuan and his partner learned that their surrogate was pregnant with twins. The twins were born prematurely on November 7, 2022, and required extensive medical care and surgeries. Yuan contacted Eightfold’s human resources department about parental leave. He was initially told that he qualified for paid company parental leave, but four days later was told that he did not qualify, although he might qualify for Massachusetts Paid Family and Medical Leave. Four days after that, Eightfold informed him that his employment would end on December 30, 2022. The opinion states that Yuan continued working until his termination, including from the neonatal intensive care unit, and did not receive paid time off or sick leave.

Yuan’s amended complaint asserted claims under Massachusetts law involving sick time, paid family and medical leave, and wages. Eightfold moved under Federal Rule of Civil Procedure 12(b)(6), which allows dismissal when a complaint does not state a legally sufficient claim. Eightfold argued that the employment agreement’s California choice-of-law provision required application of California law and that Yuan’s Massachusetts claims therefore failed.

Court’s analysis

Because the case had been transferred under 28 U.S.C. § 1404(a) from federal court in Massachusetts, the court applied Massachusetts choice-of-law rules. The court first found an actual conflict between Massachusetts and California law because the potential damages and remedies differed. The opinion gives examples including Massachusetts treble damages and possible attorney’s fees, compared with more limited remedies under the California laws discussed by the court.

The employment agreement stated that California law governed disputes concerning the agreement, Yuan’s employment, or another relationship between Yuan and Eightfold. The court held that, under Massachusetts law, this provision was not decisive because it did not clearly refer to statutory claims. The court therefore applied Massachusetts’s functional choice-of-law approach, which considers the interests of the parties and the states and identifies the state with the most significant relationship to the dispute.

The court concluded that Massachusetts had the most significant relationship. Yuan began his employment there, lived there throughout his employment, and worked remotely from there. Massachusetts also had a strong policy interest in enforcing its wage laws. The court found that other factors, including the places where the agreement was signed or negotiated, either did not favor either state or were unclear. The court also rejected Eightfold’s argument that the contacts were so dispersed that it would be difficult to determine the applicable law.

Ruling

Judge Araceli Martinez-Olguin denied Eightfold’s motion to dismiss. The court held that Eightfold had not shown that California law governed the dispute and that dismissal of Yuan’s Massachusetts state-law claims was warranted. The order addressed whether the claims could proceed under the asserted Massachusetts law; it did not decide whether Yuan ultimately would prevail on those claims.
