E. Ray Cory v. Stafford King and Another

Highway -- appropriation of highway funds -- "highway purposes." L. 1941, c. 548, §§ 13, 14, 19, and 22, appropriating moneys from the trunk highway fund to the offices of auditor, treasurer,
civil service commission (department of civil service), and commissioner of administration respectively to defray expenses
reasonably attributable to highway matters, held not violative of Minn. Const. art. 16. The test whether an appropriation
is toward a highway purpose within the meaning of art. 16 is not whether each dollar appropriated is earmarked for each particular
item of highway expense, but rather whether the charge upon the highway fund accurately reflects highway expenses, as borne
by the four offices and departments, and does not exceed the amount of expense properly attributable to highway matters.
