A Teamsters pension fund is urging the Delaware bankruptcy court to reject Yellow Corp.'s liquidation plan, arguing the trucking company is reserving potential arguments against the fund's $17.8 million claim that have already been resolved and discharged.

In an objection filed Wednesday, Local 705 International Brotherhood of Teamsters Pension Fund told the court that Yellow had said it was not pursuing an argument that the fund's claim against the company was subordinated, and therefore should not be allowed to reserve the right to pursue that position in its plan.

Yellow filed for bankruptcy in 2023 with $1.5 billion in debt, amid a highly contentious dispute with the Teamsters, which represents roughly 22,000 of the company's 30,000 workers.

A Delaware bankruptcy judge approved the debtor's latest disclosure statement in September 2025, allowing it to solicit votes on the Chapter 11 liquidation plan.

In its filing, the pension challenged the plan's reservation of the right to assert that the $17.8 million the fund alleged it is owed due to Yellow's withdrawal from its pension plan are subordinated to other unsecured claims in the case.

The fund contended that the company had "ample" opportunity to raise this argument during its objection to the fund's claims in the bankruptcy. The court has ruled on the objection, and therefore Yellow is barred from raising that argument in the future, the pension said.

It also alleged during discovery on the claim dispute in 2024 that Yellow stated it was only disputing whether the fund claim should be discounted to the present value of its pension plan contributions. The fund stopped taking discovery on other potential claim objections as a result, and Yellow should not be allowed to pursue those objections, it said.

Counsel for the fund and the debtor did not immediately respond to requests for comment Thursday.

The Teamsters fund is represented by William D. Sullivan and William A. Hazeltine of Sullivan Hazeltine Allinson LLC, Stephen J. Rosenblat of Baum Sigman Auerbach & Newman Ltd. and John S. Delnero of Pedersen & Houpt.

The debtors are represented by Laura Davis Jones, Timothy P. Cairns, Peter J. Keane and Edward Corma of Pachulski Stang Ziehl & Jones LLP, and Patrick J. Nash Jr., Shirley Chan and Allyson B. Smith of Kirkland & Ellis LLP.

The case is In re: Yellow Corp., case number 1:23-bk-11069, in the U.S. Bankruptcy Court for the District of Delaware.
