Dot Foods, Inc. v. Dep't of Revenue

Summary

The Washington Supreme Court considered whether retroactive application of a legislative amendment narrowing a business and occupation tax exemption violated due process, collateral estoppel, or separation of powers principles. The court held that the amendment's retroactive application was rationally related to legitimate legislative purposes and did not violate due process. It further held that collateral estoppel did not apply to tax periods not adjudicated in the prior case and affirmed in part and reversed in part.

Holdings

1. Retroactive application of the 2010 amendment to the May 2006 through December 2007 tax periods did not violate due process because it served legitimate legislative purposes and was rationally related to those purposes.
2. Collateral estoppel did not apply because the May 2006 through December 2007 tax periods were not actually litigated or necessarily and finally determined in Dot Foods I, and the intervening statutory amendment changed the applicable legal context.
3. Retroactive application of the amendment did not violate separation of powers because the legislature preserved final judgments in Dot Foods I and applied the amendment only to tax periods not encompassed by that judgment.

Questions Presented

1. Whether retroactive application of the 2010 amendment narrowing the B&O tax direct seller's exemption violated the Due Process Clause of the Fourteenth Amendment.
2. Whether collateral estoppel based on Dot Foods I barred application of the amendment to the May 2006 through December 2007 tax periods.
3. Whether retroactive application of the amendment violated separation of powers principles by rejecting or curtailing the judicial interpretation in Dot Foods I.
