The recent headline reporting the Supreme Court's decision involving Arizona, "High court repeals most of Ariz. Immigration law" (July 26) is factually incorrect. No court can "repeal" a law.
A court can interpret a law, hold it unconstitutional and therefore void (judicial review), or issue an injunction to temporarily or permanently block its enforcement (for a variety of reasons). Only a legislature can "repeal" a law that it passed. Only the Arizona legislature (or perhaps its voters by referendum) can "repeal" SB1270!
