Arizona Republic:  “Gov. Jan Brewer, flanked by key state legislators, reacted with shock Tuesday to a lawsuit by cities and towns and accused the local officials of coddling illegal immigrants at state expense.   But the lawsuit disputes how state officials enacted the wide-ranging law, not the substance of the law itself.  At issue is a lawsuit filed with the state Supreme Court Monday by the League of Arizona Cities and Towns.  It argues that the Legislature unconstitutionally approved policy changes that affect local development practices as well as how cities enforce requirements that people show proof of citizenship to receive government benefits.”
