After years of legal wrangling that culminated in a landmark Supreme Court decision, a federal judge ruled today that Arizona police can start enforcing the state’s immigration law.

U.S. District Judge Susan Bolton formally lifted the injunction that she originally placed on the law in 2010, just a day before it was scheduled to go into effect. Now, all the state’s police officers can carry out the parts of the law that survived.

The most scrutinized will be a portion that requires police to determine the immigration status of a person stopped, detained or arrested if there’s a “reasonable suspicion” that they’re in the country illegally.

Tuesday’s ruling may not end the legal wrangling over the law -â?? several civil rights groups, including the National Immigration Law Center, have vowed to continue monitoring the law and will bring lawsuits if Arizonans are subjected to racial profiling.
