  • Supreme Court deals near-fatal blow to Arizona SB 1070; states’ immigration efforts now in question

    In a major victory for the Obama administration, the U.S. Supreme Court yesterday struck down three of the four main provisions in Arizona’s tough SB 1070 immigration law, saying these provisions were pre-empted by federal law; the Court left in place the fourth provision – the one requiring Arizona local law enforcement during routine stops to check the immigration status of anyone they suspect is in the country illegally – but in reading the provision very narrowly, the Court left its implementation open to legal challenges on grounds that it violates racial profiling prohibition and other laws; in any event, the administration moved quickly to make that remaining provision meaningless by pulling back on a program known as 287(g), which allows the federal government to deputize local officials to make immigration-based arrests; the move means that even if local police step up immigration checks, they will have to rely on federal officials to make the arrests
