Nishihara says the hurdle for Arai's class-action lawsuit will be high, because the teachers are not suing the school for unjust punishment. They're questioning the constitutionality of the order itself.
Bunya Kato, a lawyer representing the teachers, strikes a more optimistic tone. He points to U.S. Supreme Court case West Virginia State Board of Education v. Barnette as reason for hope. In that case, the highest court ruled in favor of a Jehovah's Witness student who argued that his religion prevented him from swearing allegiance to the flag.
Arai knows the odds are stacked against her and fellow teachers, but she's not ready to give up yet.
"Once you begin the fight, you must continue fighting until the end," she said.
