Intent—1987 c 185: "In 1977, in two separate pieces of legislation relating to industrial insurance, the Washington legislature changed certain references from "workmen's" or "workman's" compensation to "workers'" compensation. The purpose of this act is to correct remaining obsolete references to "workmen's compensation" and "workmen."" [ 1987 c 185 s 1.]

Severability—1987 c 185: "If any provision of this act or its application to any person or circumstance is held invalid, the remainder of the act or the application of the provision to other persons or circumstances is not affected." [ 1987 c 185 s 41.]
