More than four years after Navy Lt. Rebekah Daniel bled to death within hours of childbirth at a Washington state military hospital, her husband still doesn’t know exactly how — or why — it happened.

Walter Daniel, a former Coast Guard officer, demanded explanations from officials at the Naval Hospital Bremerton, where his wife, known as Moani, died on March 9, 2014.

He says he got none. No results from a formal review of the incident, no details about how the low-risk pregnancy of a healthy 33-year-old woman — a labor and delivery nurse herself — ended in heartbreak, leaving their newborn daughter, Victoria, now 4, without a mom.

“There was no timeline, no records of what steps were taken,” recalled Daniel, 39, sitting in his Seattle lawyer’s office last month. “I’ve had no answers.”

Daniel, who now lives in Dublin, Calif., filed a wrongful-death lawsuit in 2015, but it was dismissed, as were subsequent appeals.

The dismissals were based not on the facts of the case but on what’s known as the Feres doctrine, a 68-year-old federal ruling that bars active-duty military members from suing the federal government for injuries.

This week, Daniel is taking his quest for answers to the U.S. Supreme Court.

Through his lawyer, he petitioned the high court on Thursday to amend the 1950 ruling, creating an exception that would allow service members to sue for medical malpractice the same way civilians can.

The military health system, with 54 hospitals and 377 medical clinics, serves about 9.4 million beneficiaries, including nearly 1.4 million active-duty members.

“I don’t want this to happen to any other family,” Daniel said.

The Supreme Court hasn’t considered the Feres doctrine in more than 30 years, since the 1987 case U.S. v. Johnson, where the justices ruled 5-4 to uphold the ruling. That decision drew a scathing dissent from Justice Antonin Scalia, who declared that the rule should be scrapped.

“Feres was wrongly decided and heartily deserves the widespread, almost universal criticism it has received,” Scalia famously wrote.

Since then, however, the court has refused to accept at least two petitions that would have allowed reconsideration of Feres. And chances are slim now. Of the 7,000 to 8,000 cases submitted to the Supreme Court each term, only about 80 are accepted.

But Daniel and his lawyer, Andrew Hoyal of the Luvera law firm in Seattle, insist that the circumstances of Moani Daniel’s death warrant new scrutiny.

“We thought if we’re ever going to take a shot at the Feres doctrine, this is the case to do it,” Hoyal said. “It was clear negligence. It was an awful situation. And every civilian in the country would be able to bring a lawsuit to get accountability, except for members of the service.

Daniel disputes the findings of a Navy autopsy concluding that Rebekah Daniel died of “natural” causes possibly linked to an amniotic fluid embolism, a rare, hard-to-prove complication of childbirth.

Daniel claims that his wife — who worked in the maternity unit where she delivered her baby — died from botched medical care that failed to stop her from hemorrhaging nearly a third of the blood in her body.

“It was utter chaos,” he recalled. “I remember multiple towels and sponges like they were trying to soak up the blood … but it kept coming.”

Doctors failed to perform vital tests, to employ an obstetrical balloon — a standard device used to halt postpartum hemorrhage — and to start massive blood transfusions until too late, court documents claim.

Just four hours after the birth of her 8-pound, 7-ounce daughter, Moani was dead.

“I was in shock,” recalled Daniel.

Capt. Jeffrey Bitterman, commanding officer of Naval Hospital Bremerton, said in an email that the circumstances of Moani’s death were “thoroughly examined in a quality review process.” The results of the review cannot be publicly released, he said, declining to comment further because of pending litigation.

However, in a press release promoting the Aloha Moani 5K run organized in Daniel’s honor, Navy officials publicly said she died “due to a rare complication of childbirth.”

Walter and Moani Daniel, who met in Hawaii, had been married nearly a decade when she became pregnant in 2013. Moani had a son, Damien, now 19, from a previous marriage.

Moani loved her job, but she had submitted her resignation to the Navy months earlier and was set to leave the service in April 2014. Walter had accepted a job in Northern California, where he had moved with Damien to get him settled in school.

The day after his wife’s death, Walter returned to her empty apartment.

“She had all this stuff for the baby set up,” he recalled. “I’m like, ‘What the hell just happened?’ It was like a nightmare.’”

The Feres doctrine holds that active-duty members of the military cannot sue under the Federal Tort Claims Act for harm “incident to service.” The justices wanted to ensure that Congress would not be “burdened with private bills on behalf of military and naval personnel.”

They reasoned then that the military provides comprehensive relief for injuries or death of service members and their families — and that there’s no parallel with private liability because the relationship between the government and its armed forces is distinct. Later, the court insisted that a primary reason for barring such lawsuits is to maintain military discipline.

But the decision, particularly the definition of “incident to service,” has been debated fiercely for years by scholars and, at least twice, in bills before Congress.

The rule has been interpreted to include not just military duty, but virtually any activity of an active-duty service member, said Richard Custin, a clinical professor of business law and ethics at the University of San Diego.

“It’s just grossly unfair,” he said. “Childbirth is not a military activity. It’s clearly not ‘incident to service.’ ”

Custin and other critics claim that the Feres doctrine strips military members of a constitutional right to seek redress for grievances, while also allowing military hospitals and doctors to escape scrutiny for negligent care.

Military hospitals reported 545 so-called sentinel events — medical omissions or errors — from 2014 to 2017, according to Defense Health Agency data. In 2014, Naval Hospital Bremerton reported at least one case of postpartum hemorrhage or hysterectomy.

But such reports aren’t public, so Daniel doesn’t know whether his wife’s case was included in those records. A 2014 review of military health care found that the rate of postpartum hemorrhage was consistently higher in military hospitals than the national average, Hoyal noted.

“What they do in the medical arena is no different than what civilian hospitals do, and they should be held to the same standards as civilian hospitals and civilian doctors,” Hoyal said.

Officials with the Department of Defense declined interview requests regarding the Feres ruling.

In an email, however, an agency spokeswoman said overturning the rule would “destroy the premise” of no-fault workers’ compensation available in the military and elsewhere. It would also “create an unsustainable inequity” between military members allowed to sue and others, such as those injured in combat, who couldn’t.
