A new law in Arkansas bans grocery stores from calling veggie burgers “veggie burgers” and calling soy milk “soy milk.”

The justification? That consumers might get confused about whether veggie burgers are made of beef and whether soy milk comes from cows.

That does not impress opponents of the law, who sued last month, arguing that the vague, expansive restrictions Arkansas put in place are an unconstitutional burden on free speech. Many legal experts say that they’re likely to win their case — but such cases can take a long time to wind their way through the courts.

For that reason, on Wednesday, the American Civil Liberties Union, the Good Food Institute, and the Animal Legal Defense Fund asked the court to stop enforcement of the law while the constitutional questions are still being considered. In an 18-page brief, they argue that the “veggie burger” law is almost definitely going to be found unconstitutional once the court reviews the full case, and that its enforcement in the meantime poses confusing, expansive, unworkable requirements on sellers of veggie products in Arkansas.

So, they argue, the court should halt the new law in its tracks — letting Tofurky and other companies keep their products on the shelves while the full case is considered.

Plant-based products are getting big. Now meat companies are fighting back.

It’s been a big year for plant-based foods. Products from plant-based meat companies like Impossible Foods and Beyond Meat have become available at restaurants around the country, and they’ve been a hit with customers. Plant-based meat producers have released new, improved products that taste even meatier, and have raised eye-popping sums of money. It used to be the case that plant-based foods were primarily marketed just to vegans and vegetarians, but they’re increasingly being consumed by meat eaters — who might prefer plant alternatives for health, animal welfare, or environmental reasons.

“Plant-based eating trends are really blowing up now, with exponential growth,” Tofurky CEO Jaime Athos told me. “We have this great moment of innovation in our industry where these products are better than ever. They’re more widely available too. And suddenly people are worried consumers might be confused. The reality is that this is a proactive decision on the parts of consumers — they understand that plant-based products are healthier for them and healthier for the environment.”

That, of course, has made some livestock producers nervous — even though sales of animal-based meat haven’t fallen at all. Animal agriculture industry representatives have called plant-based foods one of the “major challenges” the industry faces.

So meat producers are pushing back. The legislator who introduced the bill, David Hillman, said that his aim was to “protect the agricultural producers in this state”. Meat and dairy farmers argue that their competition shouldn’t be allowed to use words like “milk” or “sausage” — even with qualifiers like “almond” or “veggie.”

(Of course, not all meat companies are fighting the rise of plant-based meats — many have invested in plant-based options themselves.)

The Arkansas law prohibits companies from “utilizing a term that is the same as or similar to a term that has been used or defined historically in reference to a specific agricultural product.” That is, since the word “burger” has historically been used to refer to a product made out of meat, it’s illegal to use the word “burger” to refer to a product that isn’t. The same principle rules out labels like “plant-based deli slices” or “plant-based jumbo hot dogs.”

The law is so broad that as written, it might even ban peanut butter, though no one intended that, Jessica Almy, a lawyer on the Missouri case, told me: “While this was not the intent of the legislation, it is written so broadly that it is conceivable that peanut butter might fall under its purview.”

But is that constitutional? Would such a law run afoul of the First Amendment? The ACLU, which is suing Arkansas on behalf of the Tofurky company, argues, “The Act is a restriction on commercial speech that prevents companies from sharing truthful and non-misleading information about their products. It does nothing to protect the public from potentially misleading information. Instead, it creates consumer confusion where none existed before in order to impede competition.”

Past court decisions may lend support to the ACLU.

Federal laws prohibit labeling food in ways that are deceptive to consumers. You can’t call a product gluten-free if it isn’t, of course, or call it “olive oil” if it’s not made from olives. When laws have tried to push beyond that, they’ve generally met a skeptical audience in the courts.

In a California case, the courts ruled that a claim that terms like “soy milk” and “almond milk” would confuse consumers was nonsense. “The crux of the claims is that a reasonable consumer might confuse plant-based beverages such as soymilk or almond milk for dairy milk, because of the use of the word ‘milk,’” the US District Court for the Northern District of California wrote, dismissing the case. “The claim stretches the bounds of credulity. Under Plaintiffs’ logic, a reasonable consumer might also believe that veggie bacon contains pork, that flourless chocolate cake contains flour, or that e-books are made out of paper.”

A Florida case directly examined free speech rights as they apply to food labels. Skim milk is routinely fortified with vitamin A (which prevents blindness, and which is removed in the skimming process). A law in Florida prohibited producers of milk and milk products from selling their products if the vitamin A was left out, demanding that milk without added vitamin A be called “imitation skim milk.” A small Florida milk producer sued, arguing that their product was skim milk and that they should have the right to label it that way. The courts sided with the milk producer.

The free speech question

Does it even make sense to say that a creamery or Tofurky manufacturer has a right to free speech? The answer is yes.

The First Amendment can be applied to commercial speech — though the law is a bit complicated. In the 1940s, the Supreme Court ruled unanimously that there were no First Amendment protections for purely commercial speech. By the 1970s, the Court had reconsidered that, and overturned it in 1976.

In 1980, the Court supplied the rules for First Amendment protections on commercial speech that are still applied today. Those rules are called the “Central Hudson” test, because they were laid out in Central Hudson Gas & Electric Company v. Public Service Commission of New York.

Here are the rules: First, commercial speech “must concern lawful activity and not be misleading.” Supporters of Arkansas’s law might argue that the term “almond milk” is misleading, while opponents argue that consumers know perfectly well what almond milk is — that, as Utah Sen. Mike Lee put it, “No one buys almond milk under the false illusion that it came from a cow. They buy almond milk because it didn’t come from a cow.”

“There’s nothing misleading about the name of a veggie burger, or vegan hot dog, or seitan bacon,” Almy told me. “The packages clearly disclose that this is plant-based food that has the taste or texture of this familiar food.”

Even if the speech concerns lawful activity and is not misleading, the government can still regulate it. But it has to meet the following standards: The government must have a “substantial interest” at stake, the regulation must “directly and materially advance the government’s substantial interest,” and “the regulation must be narrowly tailored.”

There’s a strong case that bans on “veggie burger” and “tofu sausage” labels don’t meet this standard. “Tofurky Co.’s packaging and marketing materials clearly indicate that their products are plant based and accurately convey the products’ ingredients,” the ACLU wrote in the Arkansas lawsuit. “Consumers are not likely to be confused by the appropriate use of the word ‘meat’ or related terms on vegetarian or vegan products. A consumer who is looking for food that has the flavor, texture, and appearance of bacon but was not derived from a live pig would find the label ‘veggie bacon’ more useful than a label that says only ‘plant-based protein.’”

If Arkansas’s law is found unconstitutional, that’ll be good news for consumers. There is no sign they’re being tricked by the increasing prominence of plant-based burgers — if anything, they often seem to be seeking them out.
