The purpose of the Statute Law Committee and the Code Reviser, who serves as its secretary, is to function as the official bill drafting arm of the Legislature and its various committees; prepare for the Legislature all bills, memorials, resolutions, amendments, and conference reports; periodically codify, index, and publish the Revised Code of Washington; and revise, correct, and reconcile the statutes by means of administrative or suggested legislative action. The Code Reviser reviews all initiative proposals. The Code Reviser also compiles, indexes, publishes, and distributes the official session laws, the Washington Administrative Code (WAC), and the Washington State Register (WSR). All Code Reviser publications are available on line. The Order Typing Services (OTS) provides a typing and editorial service to state agencies drafting administrative rules. The Digest/Index staff compiles, indexes, and publishes the Legislative Digest and History of Bills. The Uniform Legislation Commission is Washington State's delegation to the National Conference of Commissioners on Uniform State Laws. Washington has been a member since 1905 and ranks fifth in adoption of uniform legislation.

The primary responsibilities of the Statute Law Committee and the Code Reviser are to provide a nonpartisan and confidential bill drafting service for legislators, legislators elect, legislative committees, joint committees, the governor, state elected officials, and agencies; and periodically codify, index, and publish the Revised Code of Washington and to revise, correct, and harmonize the statutes by means of administrative or suggested legislative action as may be appropriate.
