A summary of Southern California-related business litigation developments during the past week.

Two Indicted on Defense Fraud Charges: Two defense industry employees were charged with federal tax fraud counts involving their work with defense subcontractors who allegedly paid them kickbacks that went unreported to the IRS. Federal authorities said the separate criminal actions against the men represent the latest in more than 20 prosecutions to arise out of a long-term government investigation of improprieties in the defense industry. Raymond Fisher, 67, who was employed by Eaton Corp., is accused of failing to report to the Internal Revenue Service more than $40,000 in income in 1984 and 1985. The unreported income allegedly came from kickbacks Fisher collected for directing Eaton to particular defense subcontractors. Another man, Frank Brown, 56, is charged with failing to disclose on his 1986 tax return more than $7,000 he allegedly received in kickbacks for directing the business of The Hamilton-Avnet and Cetec corporations to other defense subcontractors. (Case No. 90-668, 90-669. Cases filed Sept. 5).
