PHOENIX (AP) -- A federal judge has ruled that the office of America's self-proclaimed toughest sheriff systematically singled out Latinos in its trademark immigration patrols, marking the first finding by a court that the agency racially profiles people.
The decision by U.S. District Judge Murray Snow in Phoenix backs up years of allegations from Maricopa County Sheriff Joe Arpaio's critics who say his officers violate the constitutional rights of Latinos in relying on race in their immigration enforcement.
Snow, whose ruling Friday came more than eight months after a seven-day, non-jury trial, also ruled Arpaio's deputies unreasonably prolonged the detentions of people who were pulled over.
The ruling marks a thorough repudiation of the immigration patrols that made Arpaio a national political figure, and it represents a victory for those who pushed the lawsuit.
"For too long the sheriff has been victimizing the people he's meant to serve with his discriminatory policy," said Cecillia D. Wang, director of the ACLU Immigrants' Right Project. "Today we're seeing justice for everyone in the county."
Monetary damages weren't sought in the lawsuit but rather a declaration that Arpaio's office engages in racial profiling and an order that requires it to make policy changes.
Stanley Young, the lead lawyer who argued the case against Arpaio, said Snow set a hearing for June 14 where he will hear from the two sides on how to make sure the orders in the ruling are carried out.
The sheriff, who has repeatedly denied the allegations, won't face jail time as a result of Friday's ruling.
Tim Casey, Arapio's lead attorney in the case, said an appeal was planned in the next 30 days.
"In the meantime, we will meet with the court and comply with the letter and spirit of the order," he said.
A small group of Latinos alleged in their lawsuit that Arpaio's deputies pulled over some vehicles only to make immigration status checks. The group asked Snow to issue injunctions barring the sheriff's office from discriminatory policing and the judge ruled that more remedies could be ordered in the future.
The group also accused the sheriff of ordering some immigration patrols not based on reports of crime but rather on letters and emails from Arizonans who complained about people with dark skin congregating in an area or speaking Spanish. The group's attorneys noted Arpaio sent thank-you notes to some who wrote the complaints.
The sheriff said his deputies only stop people when they think a crime has been committed and that he wasn't the person who picked the location of the patrols. His lawyers said there was nothing wrong with the thank-you notes.
Young, the group's lawyer, said he was still reading the decision Friday but noted it contained "very detailed findings of discriminatory intent and effect."
Casey said that MCSO's position "is that it has never used race and will never use race in its law-enforcement decisions." He added the sheriff's office relied on "bad training" from the U.S. Immigration and Customs Enforcement.
A call to ICE officials in Phoenix for comment wasn't immediately returned Friday evening.
Arpaio, who turns 81 next month, was elected in November to his sixth consecutive term as sheriff in Arizona's most populous county.
Known for jailing inmates in tents and making prisoners wear pink underwear, Arpaio started doing immigration enforcement in 2006 amid Arizona voter frustration with the state's role as the nation's busiest illegal entryway.
Snow wrote that "in the absence of further facts that would give rise to reasonable suspicion or probable cause that a violation of either federal criminal law or applicable state law is occurring," Arpaio's office now is enjoined from enforcing its policy "on checking the immigration status of people detained without state charges, using Hispanic ancestry or race as any factor in making law enforcement decisions pertaining to whether a person is authorized to be in the country, and unconstitutionally lengthening stops."
Snow added "the evidence introduced at trial establishes that, in the past, the MCSO has aggressively protected its right to engage in immigration and immigration-related enforcement operations even when it had no accurate legal basis for doing so."
The trial that ended Aug. 2 focused on Latinos who were stopped during both routine traffic patrols and special immigration patrols known as "sweeps."
During the sweeps, deputies flood an area of a city -- in some cases, heavily Latino areas -- over several days to seek out traffic violators and arrest other offenders. Immigrants who were in the country illegally accounted for 57 percent of the 1,500 people arrested in the 20 sweeps conducted by his office since January 2008, according to figures provided by Arpaio's office.
