The Minnesota Supreme Court on Tuesday agreed to hear a lawsuit contending that state laws make it too difficult to boot "chronically ineffective" teachers from classrooms.
The state's highest court revives a case that was dismissed by lower courts.
A state Court of Appeals ruling said it was up to the Legislature, not the courts, to make the rules on teacher tenure.
In its order, the Supreme Court granted just one issue for review: whether the court can judge the parents' claims about tenure laws harming students' rights.
Parents brought the suit, Forslund v. Minnesota, last April.
It claims the state's tenure laws violate students' rights to an adequate education. The parents said they think the seniority laws are unconstitutional.
The Court of Appeals dismissed the suit in September, in part because the court was not in a position to judge a standard for education, the appeals opinion said. Ramsey County District Court had dismissed the case previously.
Attorneys for the state have argued that changes to tenure laws should be considered by the Legislature and that the plaintiffs in the case had failed to show how the tenure laws hurt their children.
