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

Manischewitz Co. Sued: A consumers’ class action filed Tuesday in Los Angeles Superior Court accuses the B. Manischewitz Co. of fixing prices of its kosher matzo products. The suit claims that Manischewitz and unidentified “co-conspirators” prevented competition by limiting production and agreeing to increase prices of “Kosher for Passover” matzo products. The case was filed on behalf of all Californians who bought Manischewitz “Kosher for Passover” matzo products from January, 1981, until at least April 30, 1986. It seeks a court order barring the defendants from following any price-fixing plan. (Filed July 24, 1990. Case No. BC006462)
