A coalition of police and firefighters are suing Gov. Kate Brown over her mandate requiring COVID-19 vaccination for state workers.

The lawsuit, filed in Jefferson County Circuit Court, says the plaintiffs are the Oregon Fraternal Order of Police along with troopers from around the state and firefighters at the Kingsley Field Air National Guard Base in Klamath County, KOIN-TV reported.

It names the governor and the state of Oregon as defendants.

VIDEO POSTED BY OREGON TROOPER ON VACCINES MAY LEAVE HIM OUT OF A JOB

The group is asking a judge to declare Brown’s executive order "unenforceable," claiming it allegedly works against existing Oregon statutes and would result in wrongful termination of employees, according to the lawsuit.

The lawsuit comes after an Oregon trooper was placed on paid leave for posting an Instagram video declaring his intent to defy the state's vaccine mandate.

"I swore an oath to uphold the Constitution of the United States, to protect the freedom of the people who pay my salary," Zachary Kowing, 29, said in the video posted to Instagram last week. "I do not work for my governor but for them."

The order, which was announced in August as Brown reinstated an indoor mask mandate amid a surge of COVID-19 cases, requires all executive branch employees with the state of Oregon to be fully vaccinated on or before Oct. 18 or six weeks after a vaccine receives full approval from the U.S. Food and Drug Administration.

But the Kowing said the order does not account for his religious beliefs.

"I have personal and religious reasons as to why I will not take the vaccine, as well as the freedom to choose not to," he said in the video which was filmed in his patrol car, adding that he has "fallen in line" for more than a year "with these useless, ineffective mask mandates and I will no more."

The Pfizer vaccine was fully approved by the FDA on Aug. 23.

Gov. Brown’s office declined to comment to KOIN on the pending litigation.

Brown spokesperson Liz Merah said in a statement that the governor is responding to a public health crisis.

"Given the seriousness of the situation, employer vaccine requirements have become an important tool, and state government plays a part. It’s critical to protect state workers, workplaces, and facilities, as well as members of the public who use state services."
