In Daniel B. Martin v. Masters, Mates, & Pilots, Judge Lin denied remand, dismissed the union claim with prejudice, and remanded the state claim against Matson.

Who this affects

Daniel B. Martin’s claim against Masters, Mates, & Pilots was dismissed without leave to amend and with prejudice as time-barred. His remaining state-law claim against Matson Navigation Company Inc. was remanded to California state court, while Matson’s motion to dismiss was denied as moot.

What happened

Daniel B. Martin v. Masters, Mates, & Pilots concerns Martin’s challenge to a COVID-19 vaccination requirement that Masters, Mates, & Pilots and Matson Navigation Company Inc. applied to work on Matson vessels. Martin alleged that the union and Matson tried to coerce him into vaccination and that the union mishandled his grievance.

The court kept the case in federal court because Martin’s claim against the union was really a federal claim about the union’s duty to represent him. The court then ruled that the claim was filed too late: Martin knew of the alleged violation when the union denied his grievance on February 14, 2022, but he waited more than six months to sue.

Judge Lin denied Martin’s request to send the case back to state court and granted the union’s motion to dismiss without leave to amend and with prejudice. The court declined to hear Martin’s remaining state-law claim against Matson and remanded that claim; Matson’s motion to dismiss, its request for judicial notice, and Martin’s motion to stay were denied as moot.

Background

Daniel B. Martin sued Masters, Mates, & Pilots (MM&P) and Matson Navigation Company Inc. over a requirement that union members be vaccinated against COVID-19 to work on Matson’s vessels. Martin alleged that he objected on religious grounds, that Matson rejected his exemption request, and that MM&P denied his grievance. He brought one state-law claim described as “Assault / Attempted Battery / Medical Battery.”

Martin had previously filed a related lawsuit involving the same alleged conduct. In that earlier round, the court dismissed his federal claim and declined to hear his remaining medical-battery claim, allowing him to refile that claim in state court. Martin then filed this case in California state court, and the defendants removed it to federal court. He amended his complaint and moved to remand. MM&P and Matson separately moved to dismiss; Matson also requested judicial notice, and Martin moved to stay the case.

Why the Court Kept the Case in Federal Court

The court applied the “artful pleading” doctrine, which prevents a plaintiff from avoiding federal jurisdiction by labeling a federal claim as a state-law claim. It concluded that Martin’s claim against MM&P was based on the union’s alleged failure to represent him: the allegations concerned MM&P’s agreement with Matson, its failure to consult union members, and its denial of Martin’s grievance.

The court therefore recharacterized the claim against MM&P as a federal claim under Section 9 of the National Labor Relations Act concerning the union’s duty of fair representation. Because that federal issue created federal-question jurisdiction, the court denied Martin’s motion to remand.

MM&P’s Motion to Dismiss

The court held that a claim alleging a breach of the duty of fair representation generally must be filed within six months after the worker knows or should know of the alleged breach. Martin alleged that MM&P denied his grievance on February 14, 2022. The court found that Martin knew the facts underlying his claim at that time, so the six-month period began then.

Martin did not file his first related lawsuit until September 22, 2023, more than 19 months later. He did not argue that the deadline should be extended or paused, and he did not identify additional facts that could avoid the time bar. The court held that the claim was barred by the statute of limitations and granted MM&P’s motion to dismiss without leave to amend and with prejudice because further amendment would be futile.

Matson’s Claim and Final Disposition

After dismissing the only federal claim, the court declined to exercise supplemental jurisdiction—the federal court’s authority to hear related state-law claims—over Martin’s remaining state-law claim against Matson. The court remanded that remaining claim to the Superior Court of California for the County of Monterey.

The court denied Matson’s motion to dismiss as moot, denied Matson’s request for judicial notice as moot, and denied Martin’s motion to stay as moot. The court also denied Martin’s motion to remand. The Clerk was directed to remand the action to the state court.
