AGO 1967 NO. 35 >
A county treasurer is required to collect the one dollar charge prescribed by RCW 87.03.270, as amended by § 2, chapter 169, Laws of 1967, on irrigation district assessments which became delinquent prior to the effective date of the amendment where collection of the assessment occurs after that date; such a construction of the amendment does not render the act an ex post facto law.
