Wisconsin’s right-to-work law was reinstated Tuesday after an appeals court ruled that a lower court had erred in striking it down. The law’s fate remains uncertain as the state Supreme Court is expected to eventually rule on its constitutionality.

“We feel confident the law will ultimately be found constitutional, as it has been in more than half the states across the country,” said Johnny Koremenos, spokesman for state Attorney General Brad Schimel, according to the Milwaukee Journal Sentinel.
