EVERETT — Tim Eyman cannot use “B.S.” in a voters guide statement opposing a Mukilteo ballot measure, Snohomish County Prosecutor Mark Roe ruled Monday.

“Mr. Eyman is free to write letters to the editor of local papers, send mailings to registered voters, or speak to the media using whatever manner of language he sees fit,” Roe wrote in his decision. “However, the local voters pamphlet still remains a limited public forum where decorum and discourse are respected and valued.”

The statement submitted by Eyman used the term to describe arguments of backers of Proposition 1, a proposed sales tax hike measure.

Snohomish County Auditor Carolyn Weikel rejected the statement, saying B.S. is a profane term and inappropriate for inclusion in the guide.

Eyman appealed Weikel’s decision Sept. 7.

Roe’s action is final under county rules. Weikel is expected to give Eyman an opportunity to submit a new statement that does not contain any objectionable term.
