Opinion of the Court
foregoing, we adopt the Special Master’s conclusion that the Act manifests fatal defects under the Commerce Clause. IV Finally, we address a question of severability raised in the exceptions filed by Wyoming to the Special Master’s Report. The GRDA is an agency of the State of Oklahoma, and, as such, Oklahoma acts as a market participant in directing its purchases of coal. We have recognized that the Commerce Clause does not restrict the State’s action as a free market participant. Reeves, Inc. v. Stake, 447 U. S. 429, 436–437 (1980); Hughes v.

In the alternative, the Special Master looked to Oklahoma law and found the Act severable as to the GRDA, a conclusion with which we disagree. It is true that Oklahoma courts have held that valid portions of a statute are severable “ ‘unless it is evident that the Legislature would not
