Emmaus Borough Council has decided to take its three-and-a-half-year legal battle with organized firefighters to the state's court of last resort. Borough Council voted unanimously Monday to authorize its solicitor to appeal to the Supreme Court of Pennsylvania a lower court ruling that Emmaus firefighters have an unusual employment relationship with the borough allowing them to form a union and negotiate contracts. It could take the state Supreme Court months to decide whether to hear the appeal. And if the court does take the case, the borough and the Emmaus Fire Department could remain in limbo for another few years.
