What it's about

The Supreme Court rejected that rule, overruled Quill and Bellas Hess as controlling precedents, wiped out the South Dakota Supreme Court’s judgment, and sent the case back to that court (remanded).

The case concerned the dormant Commerce Clause, an implied constitutional limit on state laws that burden interstate commerce.

Question presented

Should this Court abrogate Quill's sales-tax-only, physical-presence requirement?

What the Court decided

Holding

Because the physical presence rule of Quill is unsound and incorrect, Quill Corp. v. North Dakota , 504 U. S. 298, and National Bellas Hess, Inc. v. Department of Revenue of Ill. , 386 U. S. 753, are overruled. 2017 S.D. 56, 901 N. W. 2d 754, vacated and remanded.
