Action: The Supreme Court issued its decision, invalidating several provisions of SB 1070 while upholding the 'show me your papers' provision.

When the Supreme Court heard the case, the lower court's decision had granted a preliminary injunction against several provisions of Arizona's SB 1070, asserting they were likely preempted by federal immigration law. The issue before the Supreme Court was whether those provisions were consistent with the federal immigration framework established by Congress.
The standard of review applied by the Supreme Court was based on constitutional interpretation and federal preemption principles.
The Supreme Court ruled on June 25, 2012, striking down most provisions of Arizona's SB 1070, reaffirming the supremacy of federal immigration law over state laws.
