“It is alarming that a parent would be sued for defamation for expressing opinions and making truthful statements about his son’s high school math curriculum,” Hunt said in a statement. “The lawsuit appears to be an attempt to silence Mr. Dillard and other critics of MVP, and to chill their First Amendment rights to speak about MVP’s services."
“This case is about a company attempting to use the judicial process to punish a parent who dared to voice reasonable concerns that the company’s educational program was not beneficial to his child and other similarly situated children,” Hunt said in his legal brief. “Instead of addressing such concerns in a productive dialogue, the company is seeking to silence them outright.”
"A win by MVP “would certainly cast a shadow on the idea that parents have a right to participate in their own children’s education, to criticize schools for buying particular textbooks, to voice their concerns about instruction and curriculum,” Loveless said, according to Education Week."
