Why lawsuits against COVID-19 vaccine mandates will likely fail: Experts

As some employers face lawsuits against their vaccine mandates, legal experts contend those organizations have strong legal ground.

From teachers to airlines workers, some employees who have faced termination for not complying with their company's COVID-19 vaccine mandates have gone to court to fight the decisions.

Some of the plaintiffs, such as New York City Department of Education employees, a handful of Los Angeles county public employees and United Airlines workers, have argued that the mandates should be removed, questioning the rules' constitutionality and some contending their religious rights weren't observed.

So far, these arguments have not swayed judges who have almost all ruled in favor of the employer, or not issued long injunctions while they hear the case. And legal experts tell ABC News they don't expect different outcomes in courtrooms anytime soon.

Glenn Cohen, a health law and bioethics professor at Harvard Law School, told ABC News that strong legal precedent dating back to the early 20th century gives businesses and governments the legal backing to enforce the mandates.
