ABA Journal:  The ABA has filed an amicus brief urging the U.S. Supreme Court to overturn part of a controversial Arizona law that requires immigration status checks for some people who are stopped or arrested.

The ABA brief urges the court to rule that four enjoined provisions are pre-empted by federal immigration law, according to a press release. The four provisions:

• Require police officers to check the immigration status of a person legally stopped, detained or arrested, if they have a reasonable suspicion the person is in the United States illegally. If the person is arrested, police would be required to hold the person pending federal verification.

• Authorize warrantless arrests when there is probable cause to believe a person has committed a public offense warranting deportation.
