The decision stemmed from a false-advertising claim against one of Coca-Cola's Minute Maid products, which was advertised as a Pomegranate Blueberry drink even though just .3 percent of it was pomegranate juice, according to the L.A. Times.

The claim, which had previously been thrown out by a federal judge in Los Angeles, was made by the makers of POM Wonderful juice drinks. POM Wonderful is fighting its own battle against the Federal Trade Commission for allegedly overstating the health benefits of its products.

The lawsuit was originally rejected in part because of one rule that protects food and drink makers as long as their product labels list the true ingredients in fine print. But Justice Anthony M. Kennedy, who wrote the court's opinion, said another federal law allows for lawsuits for "unfair competition through misleading advertising or labeling."

So if your kid is opening up a lemonade stand this summer, be sure to explain the risks of false advertising.
