Two entities advocating for religious and medical freedom have filed a lawsuit aimed at Connecticut’s new law repealing the state’s religious exemption for mandatory school vaccinations, promising to make the matter a test case potentially worthy of U.S. Supreme Court review.

Brian Festa, general counsel for Connecticut Freedom Alliance, who, along with We The Patriots USA, filed suit in Connecticut federal court April 28, told the Connecticut Law Tribune on Tuesday he believes the new law, which went into effect April 28, infringes on citizens’ rights.
