[JURIST] Two immigration reform groups filed suit in an Arizona state court Thursday seeking to expand the effect of Proposition 200 [PDF], a state ballot initiative approved by voters earlier this month that would deny certain government benefits to undocumented immigrants. The Proposition requires proof of citizenship before someone in Arizona can vote or receive public benefits. The suit, filed by the Yes on Proposition 200 Committee and the Federation for American Immigration Reform, takes issue with the state Attorney General's narrow definition of "public benefits" offered in a recent opinion that confined the provision to certain welfare benefits only. The reform groups would like the definition of "public benefits" to include public housing, food assistance, college education and employment benefits. The Arizona Republic has more.
