A lobbyist who ceases lobbying activity may terminate his or her registration at any time by filing with the commission a signed statement, consistent with RCW 42.17A.600(3), indicating that he or she is not lobbying or being compensated to lobby. This notice of termination may be provided on an L-2 report for the month in which termination has taken place. A lobbyist who terminates his or her registration shall file all reports required by chapter 42.17A RCW for the period during which he or she was registered as a lobbyist. The employer of a lobbyist who terminates his or her registration shall not be relieved of any duty to file the reports otherwise required by chapter 42.17A RCW.
