The Public Company Accounting Oversight Board has censured the Spokane, Wash.-based accounting firm of Williams & Webster, barring partner Kevin Williams from auditing financial reports of public companies and suspending another partner, John Webster, from such audits for one year.

The PCAOB said the accounting firm raised concerns about departures from Generally Accepted Accounting Principles during its audit of the 2003 financial statements for insecticide maker Diatect International Corp. But, the Board said, the firm ignored unresolved issues and provided a clean audit report.
