Does your state have Choose Life license plates?  States often charge an extra fee for the specialty plates, and profits go to fund abortion alternatives like pregnancy care centers or adoption programs.

The plates have been challenged in the courts, amassing a patchwork of rulings across the country.  The nation's highest court has declined to rule on this issue in the past, but the continuous compilation of varied rulings by lower courts has convinced many legal scholars that the Supreme Court needs to step in and establish a standard.

The case they have chosen to take up involves the denial of a Choose Life license plate in Illinois.  The New York Times reports,

Illinois, on the other hand, has refused to issue a “Choose Life” plate, a decision that was challenged by a group called Choose Life Illinois, which promotes adoption. The federal appeals court in Chicago upheld Illinois’ refusal in November, and this month the losing side asked the Supreme Court to return to the question of what the constitution has to say about speech on license plates.

Though Illinois refused to approve a “Choose Life” plate, it does have some 60 other specialty plates, including ones for the alumni of 18 different colleges, for people who support youth golf and for those who wish to assure you that they are “pet friendly.” Five different plates put hunters to the choice of declaring whether they like to shoot deer, ducks, geese, pheasants or turkeys.

The state also recently sold a “special event” license plate, good for only two months, saying “Illinois Salutes President Barack Obama.”

The issue for the court to decide is whether license plates constitute the "speech" of a private individual (covered under the First Amendment) or "government speech," which is not regulated in the same manner:

Illinois says that it should be allowed to decide what goes on its license plates because they convey government rather than private speech. If that is right, the First Amendment drops out of the equation, as the government is free to say what it likes.

But most of the appeals courts to consider “Choose Life” license plates have ruled that specialty plates convey the positions of the motorists involved. The appeals court in Chicago, the United States Court of Appeals for the Seventh Circuit, ruled against Illinois on this point. Specialty plates, the court said, are “mobile billboards” for “organizations and like-minded vehicle owners.”

Different courts around the country have ruled differently, so the Supreme Court ruling will in fact affect more than just the state of Illinois.  Oral arguments will likely be scheduled in the court's next term, so a decision won't arrive until next year.
