Judge rules U.S. could "suffer irreparable harm" if the immigration law is allowed to stand.

District Judge Susan Bolton wrote in her ruling that the “United States is likely to suffer irreparable harm if the Court does not preliminarily enjoin enforcement of these Sections of S.B. 1070 and that the balance of equities tips in the United States’ favor considering the public interest.”

Her preliminary injunction means key parts of SB1070 will not go into effect, until courts can rule on their legality. Here are the parts of the law that will not go into effect:

• The portion of the law requiring law enforcement officials to make a reasonable attempt to determine the immigration status of a person stopped, detained or arrested if there's reasonable suspicion they're in the country illegally.

• The portion that creates a crime of failure to apply for or carry "alien-registration papers."

• The portion that makes it a crime for illegal immigrants to solicit, apply for or perform work.

• The portion that allows for a warrantless arrest of a person where there is probable cause to believe they have committed a public offense that makes them removable from the United States.

The judge did uphold parts of the law. State & local law enforcement still must enforce federal immigration laws to the fullest extent of the law. Individuals will still be able to sue an agency if that agency adopts any policy that restricts such enforcement of immigration laws. Bolton also let stand the part of the law that creates misdemeanors crimes for harboring and transporting illegal immigrants.
