Parties in a federal-court lawsuit over Arizona’s new Legal Arizona Workers Act disagreed about its constitutionality, enforcement and economic impact on businesses and consumers during a panel discussion on Tuesday, Jan. 29, in the Great Hall. “People are very frustrated in Arizona and this country that Congress has not acted – everyone wants border security, everyone wants people to have legal status when they work here,” said Julie Pace, a Phoenix attorney who represents business groups and others in the lawsuit filed in July, shortly after the Arizona Legislature approved a law punishing employers who knowingly hire undocumented workers. “We all stand at the same ground level with these beliefs. The problem is the implementation.”
