For hundreds of thousands of minimum-wage workers around the country, the new year brings a raise. Musicians worried about copycats get some protection in Illinois. And California takes steps to reduce the power-plant pollution that is believed to contribute to global warming.

Jan. 1 brings new laws in many states, offering both a glimpse of what is on the voters’ minds and a preview of some of the issues Washington might take up. Many states take action long before Congress does.

Seven states – Arizona, California, Delaware, Massachusetts, New York, North Carolina and Pennsylvania – are raising their minimum wage. The federal minimum is $5.15 an hour. The new wages go as high as $7.50 an hour.

In Illinois, copycat musical groups who misrepresent themselves as the original artists will face fines of up to $50,000. The new law requires live acts to make it clear in their advertising that they are a salute or a tribute to the real thing.

“From now on when the public goes to a rock ‘n’ roll show in the area, they can be sure the artist is the original, and not some rip-off band,” said Mary Wilson of The Supremes. Supporters are pushing for similar laws in every state.

Frustrated by what some see as inaction in Washington, California passed a law that seeks to force coal-burning plants in the western U.S. to install cleaner technology if they want to sell power in the nation’s most populous state.

States also dealt with immigration, eminent domain and campaign finance.

Alaska will provide school systems with training to help prevent bullying, while South Carolina will require districts to adopt policies barring harassment, intimidation or bullying.

“We were getting too many complaints from parents that their children were being bullied and intimidated,” said state Rep. Robert Walker. They were “fearing to go to school.”

Crime and punishment, as always, were high on the agenda. Wisconsin took steps to guard against wrongful convictions by requiring law enforcement agencies to record all interrogations of felony suspects, with either video or audio.

Alabama and West Virginia cut taxes on the poorest, and North Carolina lowered taxes on the highest earners. New York and Oklahoma dropped the so-called marriage penalty that imposed higher taxes on married couples than on single people. South Dakota and Texas raised taxes on cigarettes.

Georgia increased from 13 to 29 the number of screening tests performed on newborns to detect life-threatening metabolic and genetic disorders. Massachusetts’ new health care law hits a new milestone, allowing those earning up to 300 percent of the federal poverty level to buy into subsidized plans.

In Indiana, a new license plate featuring the American flag and the words “In God We Trust” will be available at no extra charge.
