The Federal Working Animal Protection Act is constitutional. It operates squarely within Congress's plenary power over immigration and naturalization under Article I, Section 8, Clause 4. The bill does not restrict any right protected by the Bill of Rights, does not infringe individual sovereignty of U.S. nationals, respects decentralization by leaving state and local animal cruelty laws untouched, and provides full due process through criminal conviction or admission as a prerequisite for immigration consequences.

✓ Passes · Decentralization
The bill passes all four questions of the decentralization test. (1) An individual or family cannot handle immigration policy unilaterally; this is a federal function. (2) A local community or county cannot set national immigration rules. (3) A state cannot set federal immigration policy. (4) The bill does not consolidate decision-making upward beyond the minimum necessary; immigration is inherent… -
✓ Passes · Due process and takings
The bill provides full procedural due process. It requires a criminal conviction or an admission by the non-U.S. national before immigration consequences attach. This ensures fair notice, a fair hearing, and the presumption of innocence. No property is taken without just compensation; the bill does not involve any taking of property. The immigration consequences are civil, not criminal, and are ba…
