The commerce power is broad — and so is the responsibility that attends it

According to CNBC, the Trump administration is defending its latest round of global tariffs on the ground that trading partners have failed to effectively prohibit goods produced by forced labor. That is not a trivial justification. A nation that opens its markets to goods wrested from captive hands does not merely suffer an economic disadvantage — it ratifies the condition of those workers with every transaction. I find that argument compelling, and I find the federal commerce power more than adequate to answer it.

I argued, in my time, that the power to regulate commerce among the nations must be construed broadly enough to give the republic genuine tools in its hand. A narrow reading leaves the government able to watch injury unfold but powerless to arrest it. The modern courts have generally agreed. That the administration is now defending this position before a trade tribunal is exactly the kind of institutional contest a republic ought to have — not a scandal, but the system functioning as designed.

And yet a tariff is an instrument, not a policy. An instrument must be fitted to its purpose. If the declared purpose is to punish trade built on forced labor, then the tariff schedule must be constructed with precision — targeting the offending goods and their points of origin — rather than cast over the whole of global commerce like a net drawn without discernment. A broad tariff applied to nations that have, in fact, moved against forced labor practices is not a moral statement; it is a tax on American consumers and a disruption to the supply chains of domestic manufactures who depend on imported inputs. (I mark this as inference from general principle, not from specifics of the schedule I have not reviewed.)

There is also the matter of public credibility. The administration's stated rationale — forced labor — is serious and defensible. But if the same tariffs also serve, quietly, as a wall against competition that has nothing to do with labor conditions, the stated rationale becomes a pretext, and pretexts are detected. Foreign governments detect them. Markets detect them. And once detected, the authority to act on genuinely moral grounds is cheapened. I spent considerable energy in my own day arguing that the public credit depends on the government saying exactly what it means and meaning what it says. That principle is no less vital in trade policy.

The trade court challenge reported by CNBC is, in this light, a useful discipline. Let the administration defend its instrument on its stated grounds, with precision and evidence. If the record shows that specific nations are channeling forced-labor goods into American markets and declining to act, the case is strong and should prevail. If the record shows something more opportunistic, the court will say so, and the policy will be the better for the correction.

My recommendation: Maintain the authority; sharpen the instrument. Publish a clear, public accounting of which nations are found delinquent on forced-labor enforcement and why — country by country, sector by sector. A tariff defended by a transparent factual record is a tariff that survives legal challenge and commands public confidence. A tariff hidden behind vague assertions invites exactly the judicial scrutiny it is now receiving, and deserves it.
