Parents of a former Cheshire Academy student, who claim the private boarding school expelled their son over his conservative political views, engaged in hard-fought litigation before withdrawing their lawsuit against the school and two officials.

Theodore and Sonia Mancini filed a withdrawal in the case that had pitted their counsel against Carlton Fields, one of the largest firms in the country, according to ALM’s Am Law 200 ranking. Their May 3 lawsuit had alleged Cheshire Academy was intolerant of their son’s political viewpoints, and had expelled him as a result.
