On July 31st, the Great Lakes Legal Foundation filed an amicus brief in Tetra Tech EC, Inc. v. DNR. The case involves proper interpretation of a Wisconsin retail sales tax statue. Beyond that, the Wisconsin Supreme Court has requested parties brief the deference standards given to agency interpretation of law.
GLLF’s amicus brief on behalf of 11 business associations urges the Court to reject the current practice of deferring to an agency’s interpretation of the law. We assert that beyond an abdication of the courts’ constitutional duty to interpret the law, such systematic bias that benefits the state as a party deprives those being regulated of due process.
