Justice Neil Gorsuch published a book over the summer in which he critiqued perceived government overreach, including in the nation’s enforcement of an expansive criminal code. Yet he just passed up a chance to address a federal criminal law that he previously called out when he was an appeals court judge.
That law is known as the Analogue Act. It bans selling substances that are “substantially similar” to ones that have already been deemed illegal. The 1986 law was an attempt to combat so-called designer drugs that enter the underground market faster than the government can ban them. The law gives the authorities a wide net, one whose ambiguous shape raises the question of whether it’s too wide for the Constitution, which is supposed to guarantee notice of what’s illegal.
The vague and unscientific nature of the term “substantially similar” has prompted multiple federal judges to question its legality over the years; even chemists within the Drug Enforcement Administration have disagreed about its meaning.

Gorsuch himself wrote critically of the Analogue Act when he was on the Denver-based 10th U.S. Circuit Court of Appeals, before Donald Trump elevated him to the high court in 2017. In a 10th Circuit ruling, Gorsuch called the law “a curious animal” and said it was “an open question, after all, what exactly it means for chemicals to have a ‘substantially similar’ chemical structure — or effect.” He wondered “whether terms like those will admit of fair application and afford citizens fair notice.”
So it was reasonable to think that, even if the Supreme Court declined to review a recent case challenging the law, Gorsuch might have offered a word in passing. After all, on top of performing legal criticism on his book tour, the justice has also spoken out in actual criminal case opinions when the high court has rejected appeals that he believed raised important issues.
