In Port of Whitman County v. State, No. 00-2-01097-4 (filed Jan. 12, 2000), the Ports of Whitman County, Tacoma, Skagit County, Seattle, Longview, Kennewick, Friday Harbor, and Bellingham (Port Districts) sought a declaratory judgment that I-695 does not apply to rates, tariffs, fees, rents, assessments, local improvement district and industrial development district assessments, and other charges imposed by port districts in carrying out their functions, including, but not limited to, the operation of harbor and marina improvements, rail and motor vehicle transfer facilities, water transfer and terminal facilities, airports and terminal facilities, industrial development facilities, trade centers, and related commercial facilities. They asserted that these charges do not fall within the meaning of the term "tax" in section 2 of I-695. These parties did not challenge the constitutionality of I-695.
