Emboldened by signals that the U.S. Supreme Court may uphold parts of Arizona's immigration law, legislators and activists across the country say they are gearing up to push for similar get-tough measures in their states.

"We're getting our national network ready to run with the ball, and saturate state legislatures with versions of the law," said William Gheen, president of Americans for Legal Immigration. "We believe we can pass it in most states."

That goal may be a stretch, but lawmakers in about a dozen states told The Associated Press they were interested in proposing Arizona-style laws if its key components are upheld by the Supreme Court. A ruling is expected in June on the Department of Justice's appeal that the law conflicts with federal immigration policy.

Dan Stein, president of the Federation for American Immigration Reform, said he was encouraged that several justices suggested during Wednesday's oral arguments that they are ready to let Arizona enforce the most controversial part of its law — a requirement that police officers check the immigration status of people they suspect are in the country illegally.

The Supreme Court will decide whether to apply retroactively its 2010 decision that immigrants have a right to be told that a guilty plea could lead to their deportation.

The high court on Monday agreed to hear an appeal from Roselva Chaidez, who was in the process of being deported when the court made that March 2010 decision.

Chaidez pleaded guilty to fraud in 2004 after falsely claiming to be a passenger in a car wreck. Authorities started deportation procedures while she was applying for U.S. citizenship in 2007.

Her lawyer never told her that her fraud conviction may lead to her deportation. Chaidez says she should be able to take advantage of the Supreme Court decision that cemented that principle.

Italian confectionery group Ferrero has agreed to set aside $3 million to settle a class-action lawsuit championed by a Californian mother after she discovered the group's Nutella chocolate spread packed more calories than jam or syrup.

Notices of class action settlements said that Ferrero USA Inc., the group's U.S. division, would pay up to $4 for every jar of Nutella bought in California since August 2009, or bought anywhere else in the United States since January 2008.

The notices posted on nutellaclassactionsettlement.com said the settlement was for $3,050,000 in total.

Ferrero USA also agreed to "modify certain marketing statements about Nutella" and to give more prominence to nutrition labels on Nutella jars, the notices said.

"Ferrero USA continues to stand by its product," a spokeswoman for Ferrero said on Sunday. "We believe that it is in the best interest of the company to resolve these matters, and have reached an agreement with the parties involved."
